I just got this holster for my Glock 26. To those of you that have a Comp-Tac Spartan or similar, is it normal for the gun to have a really tight fit? Even with the tension adjustment screws backed way off, it is really tight, and makes the leather bulge in the back. I thought the back was supposed to remain relatively flat for comfort, but it is so tight that the back of the leather is bulging from the gun. Is this normal for a new holster like this?
