Most of the time, 637 in a Tagua Leather IWB dual clip holster (at 4 o clock), that i had to soften up a lot with conditioner, and I swapped the metal clips out for plastic ones, since I was wearing finish off all the wooden chairs in my house with the clips rubbing the rungs on my chairs... I also have an older blackhawk black leather speed classic holster which I use from time to time, I have a Bianchi IWB leather holster that I don't wear often because it isn't as comfortable (being it doesn't distribute the bulk of the gun as well as a dual clip holster does), and I have a Barsony OWB pancake cloth holster that is a generic size, and is very comfortable, and minimalistic.
I do want to get a 638 or classic blued Bodyguard at somepoint, just haven't found one when I had money in my pocket, or I found something cooler when I saw one (like my Simth 617 .22LR 4" revolver) I want to find a snubby .22lr as well, but they almost never show up near me, and ones I have seen online that were affordable, are usually beat up pretty badly.
I love revolvers... Love Snubbies... Love j-frames...
