here is the LCP in the wallet style holster.
I have been patted down twice by "top flight security of the world" and never had to pull it out.
ETA: I usually have a flush fitting mag in there. that pinky extension was just for pics when I got it.
as to shooting with the wallet holster...it is a little different. I find myself position the weapon so it is always toward the front part of my pocket, muzzle down and usually position my wallet in the same pocket so everything stays in place nicely.
for something cheap with kick look into a snub nose revolver. i had a eaa in .357 that fit in my back pocket
I carry G27 (.40 for the non-Glock people) in a crossbreed, a full frame Colt 1911 in a cross breed, or a .38 air-weight in a pocket holster. Pants or shorts.
Sorry, no pics right now.
