First off, I need to get out there, I'm not particularly impressed with CHPWS. I've now owned a few of their plates and while functional (for the most part) the customer service of the company is beyond lacking. Products shipped with the wrong screws, blaming the customer for not applying VC3 properly when the product was actually flawed with QC issue, proprietary secret screw sizes that they charge $8+shipping for two of, and internal e-mails trash talking their customers inadvertently sent to the customer...not a fan of #boomsquad .
Bearing that in mind, I went looking for an alternate solution for the Glock's MOS plates to recommend to our officers and for use myself. Someone I trust recommended Forward Control Design (FCD) and oh man, am I glad they did.
I bought their plate for the RMR/SRO. The retail cost of the plate was $68 (they offer and LE/Mil discount as well). I had a few questions and spoke to Roger Wang with FCD before placing my order. He was extremely prompt and straight forward. None of the shenanigans I've experienced or witnessed co-workers experience through the other company.
This is what arrived:
The plate itself is made of steel, not aluminum. As you can see, it comes with screws to mount the plate to the slide and screws to mount the optic to the plate. It also came with a Torx wrench and VC3 (which I don't use). The instructions were very clear. What I was particularly impressed by was the fact the screws were marked with what they actually are and with the torque values (well done).
The plate is very well machined and very well finished. It fit perfectly with a tad bit of friction into the MOS cut. I used Loctite 248 as the thread locker and torqued the plate to spec.
Next, I mounted the RMR. This was not just a snug drop in. It actually had some friction when placing it on the plate similar to when installing an RMR into a custom milled slide. The front of the plate actually wraps the front of the RMR a tad. Once pressed into place the RMR didn't budge. I turned the slide upside down prior to installing the screws and shook it. The optic was on the plate solid. Next, using Loctite 248 I installed the provided screws and torqued them to spec. I'm going to let it cure for a couple days before I take it to the range.
I have to say so far I'm really impressed. They make plates for the Glock MOS and for P320 and sell their products on their own and through TangoDown.
High quality and straightforward.
