Here are my thoughts about a good carry gun system.
-G19 strongside IWB
-9mm snubbie (to standardize ammo) as backup which would be worn in a weakside pocket, or in strongside coat pocket when wearing a heavy coat would slow down the presentation of the Glock.
-Mini revolver in .22LR in back pocket as hideout gun.
Any thoughts on this? Also, where might I find a 9mm snubbie?
