Great but not perfect - Comp-Tac International Outside The Waistband Holster - Glock

Excellent fit with a Gen 4 G34, but cannot get the last screw out to change the belt holster to a dropped configuration (which is why I bought it). I’ve stripped the screw, it’s too tight & hard to reach. The washers spin freely and have to be supported on both sides. Shouldn’t be this difficult. I usually buy blade-tech, wanted to try something different. Might have to drill the screw out, or send it back and wait again...too bad as the G34 fits so well, even with a threaded barrel. Took photos but no option to upload to this review.
