As CHPWS puts it, “…OEM mounting plates are the weakest link in the Red Dot System”. That’s why they offer the V4 and V4 Defender Glock red dot mount plates. Both plates increase the strength of the mounting system of your Glock 19 MOS by addressing two specific issues: the mounting hardware and optic/lens protection. If you’re looking for a way to upgrade your existing MOS plate, check these out.
First, let’s talk about the CHPWS V4 red dot mount plate.
The V4 features patent-pending replaceable stainless steel T-nuts and stainless steel Torx head screws. This is completed so if the individual strips the threads, they can replace both the T-nuts and Screws and not the plate itself. This is a great option over any other mounting plate out currently in production.
Here is what you get in the V4 plate package:
•6061 Aluminum Plate.
•Type III Mil-Spec Hard Anodize Coating.
•416 Stainless steel T-posts X2.
•Torx Head Screws X2.
•M3 screws X2.
•The package also comes with a vial of single-use Vibra-Tite VC-3.
The CHPWS V4 Defender
The V4 Defender red dot mount is different from other plates you have seen due to the protective window that sits over the front of the optic. The V4 Defender is constructed of Propriety Impact Resistant Polymer instead of the normal metal mounting plates.
It’s a very interesting concept I, was looking forward to using it and seeing how it worked with my normal equipment. The Defenders window is designed to protect the font of the optic from being struck by the shooter’s hand while cycling the slide, spent casings during live fire, or even items used to cycle the slide when completing injured shooter drills.
Here are the items included in the package:
•Polymer Plate with front Defender Window Frame which matches the front contour of the RDS (in this case a Trijicon RMR)
•416 Stainless steel T-posts X2
•Torx Head Screws X2
•M3 screws X2
•The package also comes with a vial of single-use Vibra-Tite VC-3.
Another advantage of the CHPWS system is the fact it gives you an increased thread engagement depth between the screws and T posts. This intern gives you a more robust mounted optic!
V4 and V4 Defender Installation
Installing the V4 and V4 Defender to the Glock MOS is similar to using the Glock 19 MOS plates.
The first thing is to take the included T posts and place them into the bottom of each plate. There are two T posts per plate. Once those are installed, place the plate in the opening milled into the slide where the Glock MOS plate would normally go. When the plate is placed onto the Slide, secure the plate to the slide using the silver screws. Make sure to use the supplied screws as well as the Vibra-Tite.
Once the plate is secured to the slide, place the optic on top of the slide, in the open area left between the slide and mounting plate. Using the two black screws, mount the optic to the plate. Each set of screws requires the proper torque settings, given in the instructions.
After I completed the installation of the optic, I left the pistol to sit overnight to allow the Vibra-Tite to set, properly securing the three parts together.
While at home waiting to hit the range, I start the zeroing process using the iron sights. To do this I look through the optic and align the optic dot to the suppressor height sights. This will get the dot close to my desired zero. I want to make sure I am clear this is nowhere near a zero!
This is just a starting point to allow me to waste less ammo while achieving a zero. To achieve a proper zero, you need to shoot the specific firearm, adjust, shoot, adjust, shoot, adjust, shoot, adjust. Hopefully, you don’t have to do the above to achieve your zero. You just need to have rounds hit the target, in the desired area, at the desired distance.
First Range Session with V4 and V4 Defender
Going to the range the first time, I completed a zero on two RDS pistols, each utilizing a CHPWS plate. I like to start the zeroing process at closer distances starting at the 3-yard line. I shoot 1 to 3 rounds from an unsupported standing position. At closer distances, my goal is to have all my rounds touching.
Once I am satisfied with the results, I move to the 10-yard line, repeat, 25-yard line, and repeat. At the 25 yard line, it sometimes helps to use a supported position to get a more precise zero! I finish the zero process at the 25-yard line. While zeroing, I use an NRA slow fire 25-yard Bullseye repair center target. I, as well as many others, find this to be the most precise target for this type of shooting.
What are the benefits of these red dot mount plates?
After using the CHPWS V4 and V4 defender plates for a little over 6 months, I feel there are many positives over the Glock 19 MOS plates which are included with the Glock pistol.
As a dude who has destroyed Glock plates in the past, I like the ability to replace the T post and the screw as opposed to the complete plate. With this option, you don’t have to replace the expensive part of the mounting system. All you need to do is remove the plate, swap out the T post and screw, re-install the plate and re-install the optic. It’s an amazing option, I wish it was a common feature on every new MOS pistol.
With the plate’s T post and screws, you get a better mounting interface for the unexpected use and abuse on the RDS pistol it is installed on. This added strength will bode well for the dudes out there using their pistol when it all matters. If I had to strike my RDS pistol on of a car due to an injury, I would feel more comfortable knowing it had the added strength of the CHPWS mounting plate and technology.
The look of the CHPWS mounting plates is very appealing. The V4 itself has awesome lines and it covers the underside of the optic. This increases the longevity of the optic due to the increased sealing abilities of the included surface area.
Is there anything negative about them?
The only negatives I can think about is the fact I will have to buy more plates because I know for sure they are a better widget. This is not to say you can’t use the Glock plate, I just know you get a better mount from CHPWS.
Due to the fact I need to buy more let’s include the cost for the two types of plates. The V4 is currently $69.95 and the V4 Defender is $79.95, both are on the CHPWS website as in stock.
What is my overall opinion about the CHPWS V4 Series?
If you are looking for an option to replace your existing Glock 19 MOS plate, take a look at the products from CHPWS, they are currently making products for the following pistol platforms, Glock, Sig Sauer, Smith and Wesson, Staccato, Walther, H and K, FNH, Springfield Armory, and CZ. So if you have one of these pistols they have a red dot mount option for you!
