I'm looking for an IWB holster for my P-01. I currently have a Galco M5X Matrix OWB. It works well for the range a stuff, but being skinny, the bulge is noticable, and I don't like that the barrel can stick out under my shirt when I lift my arms. I noticed when I stick the holster inside my waistband the bulge of the gun dissapears, and is really touch to notice even when you're looking for it. So I think and IWB would be good in addition to my Galco. My budget is around 40$. I won't be carrying it that often.
