This might be a little late, but.....
I have been carrying my Glock 26 daily now for about a year in a Galco Ultimate Second Amendment. This is the first IWB holster that I have ever owned, but it seems to work great. It doesn't shift, or move, and with a little practice, drawing is just fine. I stand 5'10", about 220, and wear an untucked button down shirt over jeans. The pistol sits on my hip and hides very well.
