According to the Kimber website, the grip on the Compact Stainless II is slightly shorter than the full sized frames.
Could be, I get all their names confused with the "line extension" they have. Does it take a 5" full size mag?
My Series I and my gunsmith's Pro Carry II "look" the same, mine is all steel, his is naturally steel and alloy. They use the same mags, grip is same, his bbl is shorter.
He took this gun, directly out of box, fired ~ 980 before a FTF. Cleaned it and we ran another 1500 rds before we ran out of ammo. We shot weak-handed, sidewise, upside down , holding with only 2 finger and the like.
See we run the guns in every imaginable way. Our CCW has to run everytime, in any position. We train to shoot on back shooting the gun "upside down" , sidewise with both ejection port up or down ( so your downed and only shot is under vehicle) Weakhanded, On purpose limpwristing.... We run min of 500 rds of any ammo considered for CCW.
Then he adjusted the trigger, cleaned,lubed, and smoothed one little place on safety . I then ran 2k the next day with 3 choices of carry ammo, while he was teaching a class. NO failures.
IME and his we test our CCWs this way. We ask ourselves will the gun run if I'm hurt/bloody/weak/ have to shoot weak-handed/ limpwristing any at all/ in any position. NOT all guns will, NOR do most even check their guns and loads to see. The 5" guns do this better-period. The second best is the Commander/Pro Carry size.
My guns will, will yours?
