New at CCW - still experimenting.
S&W 6906 in an Uncle Mike's belly band w/body armor holster (velcro), arranged two ways:
1) Belly band around midriff, just under pecs, arranged for crossdraw under my left arm. Nice and concealed in that location, under an XL T-shirt or button-down untucked. A smaller gun would give me more options - the pinky rest on the mag does protrude a bit, but I like it to shoot with.
2) Just the body armor holster, tucked under my belt so the gun is upside down with the slide parallel to the ground and the grip to my right, in reach of my strong hand. Grip protrudes about 2-3" above my belt, but the rest is totally concealed in my jeans. Move it around a little to find a comfortable fit, and then I just forget about it. I really like this setup, but I've never seen a holster designed for it. I may have to invent one...
