good point... again, my not carrying a Glock is completely due to me not taking the time to properly train myself to where motions are committed to muscle memory. some of this is due constantly changing weapons.
a major reason is my chosen CCW of a revolver. so recently what brain cycles, dry firing, range time, reloading, etc is committed to revolvers. recently purchased a S&W 66-2 .357 specifically to spend more time with a revolver.
just loaded up another 200 rounds for the next trip to Sand Springs Gun Club. If Glock was on my brain the same way...
I've got the same gun but a -4 I believe. Get a hogue grip and you'll love that thing.
