I read the thread, every post. There are some nice holsters listed. As you are new to this, you are going to look at the prices and think, WOW, those are high dollar, and some of them are.
BUT. when you think about it a nice holster makes toting around a gun a lot more comfortable. I would recommend a holster, but I'm not. I will say, don't cheap out, and don't get all but hurt,(with yourself) when that $120.00 holster just doesn't feel right. That's the breaks, its going to happen, get ready for it. Because what works for me, or anybody else might not work for you, actually probably wont.
A holster is, in my opinion, and most people from what I can tell, more personal than the gun. So just get used to the idea right now that you will end up with a drawer full of holsters, leather, kydex, leather and kydex, nylon and kydex, customs, and at some point just shoved inside your waist band or in your coat pocket.
I will say this, pick a spot, right hip, small of the back, left hip, appendix, IWB, OWB somewhere, and stick to it. More than 1/one person has grabbed for their pistol and realized it was in a different place.
Mines right hip, OWB. always. I just dress around it, for the last 12 years, before that small of the back, for 14 years or so. Went with a 10 to 11 o'clock cross draw for a few months, mostly because I thought it was cool, no other real reason.
Good luck on the choice, and what ever you get, spend a few hours a week for a while drawing and dry firing with what ever you wear the most, and in a couple of years you wont even think about it.
Good luck and enjoy the holster collection.
