IWB Holster?

I would highly recommend raven concealment or JM custom kydex. I would also recommend giving some serious consideration to appendix carry, it works well for a lot of people.

 

I'm carrying a Springfield armory xd subcompact .40s&w.
I'm really not a small guy I'm 5'10 and about 190. Just don't wanna be uncomfortable while driving and walking around. The belt holster is easy to conceal I'm just worried about in just a t shirt. My shirts would only cover half the gun that's why I'm looking for an iwb holster

 

Not if it is made out of horsehide. Horsehide wicks the moister away.

 

Yeah I've read that a lot lately and I can see it working well for standing and walking, but for prolonged sitting or in situation s where you need to kneel or squat????
I'd think it would dig in to the abdomen and thigh

 

A lot of weather it digs into your abdomen or thigh is a function of holstered and gun. It will to an extent with any gun but then again, if you carry at 4 o'clock it will dig in when you sit down too. Appendix carry is also the fastest position when it comes to draw times.

 

I'm with this guy, I have uncle Mikes in-the-pants holster for both my Springfield XD 45 and my sig 9mm, love them both. Not terribly expensive either, maybe 20-25 bux? Had a friend turn me on to them a year or two ago and I haven't looked back.
