I shot a few stages with an AXG/Lok brass grips 320 last week and liked it a lot, everything felt a little more communicative with really good ergonomics. I did not like the recoil impulse though, and this is one of the major reasons I shoot my 320s over my Shadow2 at times for Carry Optics. I’m not recoil sensitive at all, but the way the polymer or TXG chassis flexes allows the gun to absorb a lot of recoil and tracks a red dot better than most by keeping the dot in the glass during quick double taps, whereas the AXG has a sharp recoil impulse that made me loose the dot during a good part of every shot (which is something I don’t do even on most full metal guns). I’m sure with more practice, this is something I could get used to, but I think there you’re removing one of the major advantages of the P320 over other competition platforms by swapping to a more expensive metal chassis. I still think a slightly modified TXG chassis is the way to go with the 320s for competition.
