Keeping a gun hidden with pocket carry
I bought my first gun this week (S&W 640, J frame) and plan to carry concealed. I was originally planning on pocket carry (with a holster) but I've noticed that the back end of the grip is visible from behind or above. It's hard to see in the picture but the black thing is my gun. Click the image for a larger version.
The pockets of those pants are about 7 inches deep. If I take the gun out of the holster, it slides down farther into my pockets so that you can't see it anymore, but then it prints and besides, I want to use a holster.
How should I deal with this? I've thought about deepening my pockets, getting a different pocket holster, or carrying inside my waistband instead. The reason I wanted to pocket carry is that I sometimes have my shirt tucked in and still want ready access to my gun. I ride my bike to church (with my shirt tucked in) through a part of town that isn't entirely safe. I'm not sure which would be faster when I'm on my bike: to draw my gun from my pocket or to untuck my shirt and draw my gun from an IWB holster.
Also, I think the bulge of an IWB holster might be too noticeable on me because I'm 6'3", 145 lbs. If I pocket carry, I suppose most people won't be paying enough attention to look inside my pockets and recognize that I have a gun, but I don't want to take any chances. Any thoughts?
