Newbie to forum, but here's my two cents
Been carrying 20+ years....started with Smith K frames, and from then to now, 1911, Beretta M9 (92F), Sig M11 (M228), Glock 19/23.
Have settled on J frame 37 in pocket and Glock36 in Hume JIT as my cc guns, (based on worldwide availability of ammo) and adjust based on the situation from there.
