This has been on my mind lately. Not so much proficiency of the two, but really choosing between the two. I unfortunately became enomored with the PCC and plopped down more money then I wanted on a GMR 15 with the intention to to start compteting quite a bit with it. However I got bitten bad with the pistol bug with regards to completion and am fully in 100% with USPSA pistol matches. I spend every day dry firing and working on getting better so the PCC (an expensive one) sits in my safe. I just don’t want to take away practice or match time at this point away from my pistol.
I actually wish with they would run 2 gun matches, that way could run my PCC but still work most by time with my pistol.
