hammy517 The plastic rails are not there for slide function but to help put it to gether. After they break in ,they stop wearing . Kahrs runs on metal to metal. Maybe the bullet you are useing causes your slide not to sling shot?? Maybe your not pulling it completely to the rear and releasing it cleanly. It is a short stroke slide. I use a gold dot bullet and both of mine from round one would operate how ever you work the slide.
All companies do make some problem pistols, all of them. But some of us have also bought those pistols that caused one person problems and they had zero issues with the same handgun.
Comfortable holster. I have a Comp-Tac that is very comfortable . I bought the monotaur neutral and carry at the 2:15 position . Soft tanned with a glove leather backing to cover the hardware. You can change the plastic holster also for different brand or size handguns and not have to buy a new rig. They offer to many designs to make it easy.
