Anyone here have any long-term experience carrying their Glock in a Sidearmor IWB holster? Just wondering how they stack up in terms of quality and fit. I am a little hesitant to purchase a gun holster made in kydex - I have had many knife sheaths in this material and some were very good while others were crap. Does the holster keep the gun snug while still allowing for a quick and solid grip/draw? I am especially interested in the concealability of the holster (i.e. how it rides behind the hip, close to the body, etc.) and the comfort. I live in a climate where I will often only have a loose t-shirt out over my pants/shorts and the gun will be directly against my skin. Wouldn't want scratchy kydex and rough plastic edges tearing into my side all day. Any experiences with these holsters would be much appreciated. Thank you.
