I have been using 40 minor in production for a while now. Practice with 165s, use 200 for matches. Of course with Blue Bullets. With the 200s I get that "Are you sure you are making power factor"? 640 fps = 128 PF
I checked, it's for Glock lowers. I have a Colt.
The Colt ramp helps but it's far from perfect. The AR in 223/556 is near perfect!
Every PCC shooter get the nose up jamb every now and then.
LOL, I'm just surprised a long-gun can beat a handgun in a handgun COF.

I wouldn't cut any. David O set up one of my Beretta's. What he did was polished the heck out of the block but the spring seems to be stock. With all the crud that can build up you don't want the block hanging up in there. My 2 cents
