Ive been carrying full size pistols for a long time, a Glock 17, 92FS and CZ85B, but sometimes especially during the summer days I find it difficult to carry concealed a full sized pistol so I leave it at home and take only my folding knife with me. But as I always wear some kind of vest Id like to get some new smaller pistol that I could carry in a pocket. Those are my choices: G26, M&P340 (Id use a .357 ammo) and Beretta 84FS Cheetah? So based on your experience what would you advise me to get and why? Thank you very much.
