Several months ago I bought a CAA MCK kit for my Glock 19x (pictured below). My God is it fun!
I’ve had zero issues with it out of the box. Just a great way to make one gun feel like two.
So I grabbed a MCK kit for my Glock 34 and 41 (the same kit fits both). I took it to the range today with my Glock 41 and immediately noticed it was much more difficult to install and click in to place. Once it was in and cycling ok, I started to sight in my red dot. I set it up the exact same as my Glock 19x, with a Vortex red dot on a riser.
It shoots so low I ran out of turns on the optic and was still crazy low at 7 yards! I took off the riser and even with the optic completely cranked it brought it up to maybe 6” low.
Anyone have experience with the MCK for Glock 41’s? I want to figure out what I’ve done wrong, it has to be user error.
