I currently have a Glock 22 Gen 4 and recently bought a BLACKHAWK SERPA CONCEALMENT HOLSTER RIGHT HAND MATTE FINISH GLOCK 17/22/31 (sorry for caps that's the title of the holster), but I've found that it's a littler harder to conceal than I anticipated. I'm 5'11" and about 190lb medium build. I only have a select few shirts that are even long enough to cover the weapon, let alone keep it from printing. I want to know if this is because of 1) my clothing, 2) the gun, 3) the holster, or possibly a combination of any one of them. I would like some input on those who carry G22 daily, or those who have carried quite a few glocks and found their preference. I really appreciate any and all input.
