This occurred to me because, like most gun geeks with a carry permit, I am amassing a box o'holsters. Some of 'em work. Most of 'em don't, or not well enough for your purposes, or they're just not comfortable for you, or something like that. I just found myself quietly chuckling over the guys trying different holsters, and Dean mocking Sam for using the goofy-looking (but remarkably effective and comfortable) Thunderwear. ("Sam, you got a J-frame Smith & Wesson over your crotch, or are you just happy to see me?")
For the record, I use a BladeTech inside-the-pants Kydex holster for my Glock. Not as comfortable as leather, but there's no break-in, it's great on draw and replacement, and the hold is very secure.
