RASOB what model holster is that?
I was wondering the same thing. Here in Phoenix just about everyday is "shorts and Tee-shirt" weather so my carry piece is also a pocket pistol. I went with the Beretta "Tomcat" which is a .32. I know a .32 is not much but as the saying goes better the .32 you are carrying than the .45 you left at home.
I will have to try that back pocket carry. Any issues with sitting other than "Ruger" getting tattooed in to your ass cheek?
