I bought 2 m213, 2 comps and 2 grips.
I put the parts on one and keep the other like I bought it..
I'd say 500 though 1 and 200 though the original looking one. I've polished feed ramps, etc and after ~500 rounds the gun has smartened up real nice. It's slick and reliable with all pointed 9mm ammo. Doesn't like the truncated cone stuff as much but still not bad.
I might give the slick one to my old man for christmas as he's just started coming around to pistols and I just bought a Dan Wesson 15 in .357.... yay for nice revolvers.
