I carry a S&W 340PD in an Uncle Mike's size 3 pocket holster. Never had a problem of any kind with that holster. It stays in the pocket when I draw the revolver.
And yeah, like many of you, I've been asked, "What should I conceal carry now that I've gotten my CCW permit?" The ultimate answer is based on the experience of the individual. We've seen people who buy a handgun and a 50 round box of ammo and are set for life. Others may be life-long shooters, but never considered concealed carry until now.
There no magical formula that quickly leads to the perfect CCW handgun. It's a matter of trying various handgun platforms and see what works. What works is putting holes where you want them....on a paper target of course. Practice and hone one's skills. Be confident in yourself, handgun/ammo, and related equipment for concealed carry. Hits on the target is what we are after. I'll take hits with a .22 anytime over misses with any other caliber. While a .22 is not ideal, I certainly don't want one of those bouncing around in me!
