Red Dot Sight Revolver Project: Leupold DeltaPoint Pro

Welcome to the first red dot sight evaluation of the Red Dot Sight Revolver Project! To view previous entries in this series please visit the Red Dot Sight Revolver Project pageThe Leupold DeltaPoint Pro is a popular miniature red dot sight. Several features have made it a popular choice for competition and self-defense roles. My primary use for this optics lies on the competition side of the fence. This is a very popular optic on the market, so I wanted to put it through my testing procedure. Here are some of my thoughts on this red dot sight!


DeltaPoint Pro



The DeltaPoint Pro is one of the largest red dots on the market. Perhaps the most notable feature is the optic's large window and shroud to protect the lens. This offers a very wide viewing range. I've heard many complaints regarding the size of red dot windows. This lens allows for very quick target acquisition and tracking. Leupold's lens treatment does not have the bluish tint present in other optics. While I really appreciate the more accurate colors, I did notice a bit of glare in bright sunlight. There are two different reticles available for the DPP: a 2.5 MOA dot and a 7.5 MOA triangle. I wasn't sure I would like the large triangle, so the model I selected featured the smaller dot.

The optic body is very tall to accommodate the top mounted battery compartment. Several optics require removal from the mount to swap the battery, but the DPP's design does not. Changing the CR 1632 battery is quick and easy with the hinged door. The latch requires a deliberate action to open, so I can't imagine the gate popping open of it's own accord. The adjustment button is located on top of the battery door. Pressing the button turns the optic on and adjusts brightness in a linear fashion: all the way up then all the way down. I would have preferred two smaller buttons, but I understand why a single button was used. Before proceeding to my test results, I would like to discuss some of the ways the optic can be mounted to a handgun.


Mounting Options


Allchin Gun Parts


Allchin Gun Parts Mini STS Scope Mounts are available for  several optics for both Smith & Wesson and Ruger revolvers. This model is compatible with both the Leupold DeltaPoint Pro and Sig Romeo 3. Each mount ships with two alignment pins, two optics screws, and three frame screws to securely mount the optic to the pre-drill S&W frames. These are available in clear and black anodized finishes for $45.00 - $55.00. These mounts have not officially launched, but should be available soon and if you are a Ruger fan, a compatible mount is also in the development!

Outerimpact M.R.A


While milling slides for optics is preferred by many shooters, the Outerimpact M.R.A offers a non-permanent solution to mounting several optics on an OEM slide via the rear sight dovetail. The M.R.A ships with a plethora of screws to mount the plate to the slide and various optics to the plate. The M.R.A. is a great way to test optics before committing to slide milling. The DeltaPoint Pro may seem to sit very high on the slide, but this did not hamper shooting in any way. These are available for $50.00 and are a great way to try an optic on your automatic!
  
Raptor Engineering

  
Raptor Engineering offers several mounts for Smith & Wesson, Ruger, and Freedom Arms revolvers. Raptor mounts are very low profile and include three screws to mount to pre-drilled S&W K/L/N frames. Due to the low profile nature of the mount, alternative screw may also be include if the optic's factory screws are too long. These are available in a clear anodized finish for $40.oo. 

Glock M.O.S

  
The Glock M.O.S system is available on several Gen 4 and Gen 5 Glock models. The slide is milled wide to allow for several optics to be mounted. Four plates are included to fit the most popular optics on the market. The DeltaPoint Pro requires installation of Plate 04. This is a great way to see if a slide mounted optic is for you! If you decided you don't want an optic anymore, you can simply install the slide cap that replicates the normal slide profile.

Iron Sights vs. DeltaPoint Pro


The third goal of the RDSR Project is to compare optic equipped and iron sighted handguns. After comparing the optic data averages with the iron sight averages, it appears there is a slight performance increase with the DeltaPoint Pro over iron sighted handguns in several drills. 
 
  
The Bill Drill is only shot once rather than three times. The data suggests that the Red Dot Sight Automatics (RDSAs) performed better than their iron sighted counterparts. On the other hand, the Red Dot Sight Revolvers (RDSRs) performed worse than the iron sighted revolvers. The S&W 929 and S&W 66 times certainly are comparable, but the penalty time doesn't help.
  

Excusing my performance with the S&W 929, the Box Drill results show a significant advantage to the DPP equipped platforms compared to iron sights. The other test subjects showed a thirteen (13) to sixteen (16) percent increase in speed over traditional sights. This performance increase may justify a red dot sight to those unsure of the benefits of optic equipped handgun.
  
  
The Bullseye Drill results really highlight the advantages of a red dot sight over iron sights. Excluding the Glock 19 performance, both optics equipped revolvers saw a five (5) and percent increase in speed. The Glock 17 saw a seventeen (17) percent increase over the iron sight model. These are significant improvements in speed. I am impressed with these results!
     
  
The Reload Drill is included to determine if the presence of the large DeltaPoint Pro would hinder reload speed. After reviewing the data, I would say that the optic does impact the reload. With the exception of the Glock 17 M.R.A., all of the optic equipped platforms saw increased reload times. These results have me considering how the other, slightly smaller, optics will fair?


Revolvers vs. Automatics


The fourth goal of the RDSR Project is to compare and contrast Red Dot Sight Revolvers (RDSR) with Red Dot Sight Automatics (RDSA). After the first optic and iron sight comparisonthe data gathered suggests that RDSAs have the advantage over RDSRs. This is especially true if a timed reload is included. The lighter trigger pull and simpler reloads will always be an advantage for automatics, but in just the opening shots of a stage, I believe the RDSRs can hold their own. I am looking forward to more data and further comparisons among the platforms.

Conclusions

  


The Leupold DeltaPoint Pro is a big optic, but the features gained from the large size are well worth it. I was a bit worried that the size of the optic would translate to addition recoil on the automatics. Luckily, the felt recoil did not noticeably change when compared to iron sights. The top mounted battery compartment is a great design that does not require the optic to be removed and re-zeroed when a battery change is needed. 

Most of my dot experience thus far has been with larger 6 MOA options, but I decided to try the smaller dot rather than the larger triangle. The 2.5 MOA dot is significantly smaller than other optics I have used in the past. While acclimating to the small dot required a little trigger time, I found myself just as happy with the smaller dot by the end of my testing process. The smaller dot was actually helpful in making accurate head shots in two matches I was able to shoot with the DPP. I even managed to place top 10 for the first time! I really enjoyed this optic and would definitely recommend for revolvers and automatics alike! 

As always, if you have any suggestions for future posts or would like to share your experience on the current topic please post below!

Red Dot Sight Revolver Project: Iron Sight Results

Can't seem to find the S&W 66 picture.


In the overview of the Red Dot Sight Revolver Project, several goals were established. Today's post will be the first step in answering the following question that was raised in the project overview.

What are the advantages and disadvantages to optic equipped revolvers over iron sighted models?

Data from both iron sighted and optic equipped handguns is required to make any real comparisons. Like most shooters, I have significantly more time behind iron sights, and thought this was a great place to start. The iron sight results will also serve as benchmark data for the project and will be featured in every red dot sight review.

A bit further down the page are the data tables showing the results of iron sight testing in four drills. My job requires staring at spreadsheets off and on all day, so I don't want to punish the readers with that. Instead, I've selected three categories to compare, but the complete data tables are also included. The categories are:

Performance - Fastest to complete each drill. 

Draw - Fastest from the holster to first shot on target. 

Splits - Fastest average split time excluding the draw time.


Platforms


Before moving on to the data tables and interpretation of the results, I've included the stats for each of the handguns in the iron sight test. With the exception of the 929, all front sights feature a fiber optic rod. Both revolvers are equipped with rubber Hogue grips without finger grooves. The Glock 17 sports the factory Gen 4 texture, but the Glock 19 features a stipple job with the finger grooves removed. Here are the specifications for each platform used in this test:

Smith & Wesson 929
Caliber: 9mm
Barrel Length: 6.5 inches
Weight: 44 ounces
Grips Frame: Rubber/Full
Trigger Pull: 7.5 pounds
Sights: Black Front and Black Rear

Glock 17
Caliber: 9mm
Barrel Length: 4.49 inches
Weight: 22 ounces
Grip/Frame Length: Texture/Full
Trigger Pull: 6.5 pounds
Sights: Red Fiber Optic Front and Black Rear

Smith & Wesson 66
Caliber: 9mm
Barrel Length: 3.25 inches
Weight: 33 ounces
Grips Frame: Rubber/Full
Trigger Pull: 8.5 pounds
Sights: Green Fiber Optic Front and Black Rear

Glock 19 (23 with Conversion Barrel)
Caliber: 9mm
Barrel Length: 4.02 inches
Weight: 22 ounces
Grips Frame: Texture/Compact
Trigger Pull: 6.5 pounds
Sights: Red Fiber Optic Front and Black Rear


Bill Drill



Performance
S&W 929: 2.94 
S&W 66: 3.23
Glock 19: 3.31
Glock 17: 4.44
Draw
Glock 19: 1.78
S&W 929: 1.82
S&W 66: 1.99
Glock 17: 2.25
Splits
S&W 929: 0.22
Glock 17: 0.24
S&W 66: 0.25
Glock 19: 0.31

In the Bill Drill, the S&W 929 scored the highest in two of the three categories: Performance and Splits. The 929 was .03 seconds behind the Glock 19 on the Draw. The S&W 66 was second in Performance but third in both Draw and Splits. The Glock 19 had the fastest Draw during this drill but was third in Performance and the slowest Split times. The Glock 17 was the slowest in both Performance (even without the penalty time) and the Draw. The Split times weren't terrible, but this was not stellar performance for a full sized automatic. 


Box Drill



Performance
Glock 17: 6.26
S&W 929: 6.69
S&W 66: 8.02
Glock 19: 8.27
Draw
Glock 17: 2.18
S&W 929: 2.28
S&W 66: 2.38
Glock 19: 2.42
Splits
Glock 17: 0.75
S&W 929: 0.81
S&W 66: 0.83
Glock 19: 0.84


In the Box Drill, the Glock 17 was the best platform in all three categories by a significant margin. The S&W 929 followed closely in second place in all three categories. The S&W 66 and Glock 19 Performance were significantly slower, perhaps due to the compact size. The Glock 19 did not perform well in this drill, finishing in the bottom of each category. 


Reload Drill



Performance
Glock 17: 3.81
Glock 19: 4.45
S&W 929: 4.78
S&W 66: 6.00
Draw
Glock 17: 1.36
S&W 929: 1.53
S&W 66: 1.58
Glock 19: 1.64
Splits
Glock 17: 2.45
Glock 19: 2.81
S&W 929: 3.25
S&W 66: 4.42

While the Performance and Draw are both still important data sets, the Reload Drill is focused on comparing the reload speed of each platform. Let's be honest, unless you are as skilled as Jerry Miculek, a magazine fed automatic is going to reload faster than a revolver loading with moon clips or speed loaders. What I was interested in was exactly how much faster. At my skill level, it appears that my magazine reloads are only 0.80 to 0.44 seconds faster than my moon clip reloads. My speed loader reloads are significantly slower, but again, many shooters already understand that speed loaders are not as fast as the name implies.


Bullseye Drill



Performance
S&W 929: 5.85
S&W 66: 5.98
Glock 17: 6.41
Glock 19: 6.91
Draw
Glock 17: 2.50
S&W 929: 2.63
S&W 66: 2.78
Glock 19: 2.91
Splits
S&W 929: 0.94
Glock 17: 1.12
S&W 66: 1.27
Glock 19: 1.33

In the Bullseye Drill, the S&W 929 was the fastest in both Performance and Splits. The Draw was slightly slower than the full size Glock 17. The S&W 66 earned the second place in Performance, but both the Draw and Splits were near the bottom. The performance of the Glock 19 places it at the bottom of each category. It is interesting that both revolvers results show faster times in Performance than both automatics. 


Conclusions


Some of the red dot sights in scheduled for testing.
  
This round of testing shows the two full size handguns in direct competition for the top position. I can't say that this is particularly surprising. Larger frame handguns are typically easier to shoot more accurately and faster. The results certainly reflect that concept. Gun shop wisdom suggests that "revolvers are more accurate that automatics" but I've never tested this before now.

I've considered the possibility that the non-reciprocating sights on revolvers may result in slightly better accuracy at distance when compared to tracking the sights on a reciprocating slide. After looking at the data from the Bullseye Drill, this might be a reasonable conclusion. I look forward to seeing how the additional data from red dot sight testing will support or contradict my thoughts. 

Many of the conclusions drawn from this testing reinforced my understandings of both the limitations of revolvers and advantages automatics. The results of the iron sight testing will be used to compare irons to optics in future posts. Testing of the first red dot sight is now also complete. Please keep an eye out for this post soon!
