    Love this plate, and it’s WAY better than the Glock version. The only thing I wish was better was the instructions. It was difficult to tell which screws to use where when putting it together, even with the video, so I damaged the threads on the Glock slide putting it on. Some of that is user error. I certainly could have tried the screws before using the driver!

  2. Christopher Hull (verified owner)

    Purchased on 12/28/21. The plate is roughly the thickness as the MOS plate but the 2 bosses on the front of this plate are visually shorter (no use of micrometers or calipers) and than the bosses on the MOS plate. This maybe negated by the fact that the tnuts are essentially 2 extra bosses to help take the force of recoil off of the threads. I followed their prep instructions to the last detail and when any torque was applied to the first screw that engages with the tnut, the tnut sheared. I contacted CHPWS and haven’t heard anything back. With that being said they have a tnut upgrade program that is free minus the $10 shipping. This is the why I am giving this 1 star:
    1) CHPWS knew they had an issue as far back as 11/21 with their tnuts, and are either still sending out the outsourced tnuts or the quality of the in house production is lacking, allegedly.
    2) Their customer service sucks, based on the fact I have not heard anything back from them as of this review and for the fact they are charging shipping in their tnut upgrade program even though they should bear all responsibility for having a defective product essential to the whole system working.
