So I tried a uncle mike's...adds too much thickness for my liking...as any on the market "pocket holster" that isn't made of kydex would. I settled on my own concoction.
I took one of these
I cut all the threads down both sides so that if unfolded in two. I then cut it in half. I'll post a pic when I get home.
It hides the gun in my pocket and isn't too thick. Has better stickiness than a cloth holster and covers the trigger.
Covering the trigger is the most important part. Others have a lot of good reasons, but safety needs to be first. Bumping or brushing against something in just the right way, and things could get real ugly. I rarely pocket carry, but one thing that bothers me most, is sitting in a chair and realizing my pistol, "In my pocket" is pointing directly at someone else. HOLSTER ALWAYS!!! NO EXCEPTIONS!!!
