I just broke my second one on my Kahr PM9 I've had since 2013. The first time was two years ago and I figured it was just normal wear and tear, but now I am not so sure.
I do dry fire a good bit (about 150-250 dry fires per week by my very rough estimate), but always with snap caps. I am going to have Kahr take a look at it, but in the meantime I was wondering if anyone else has had this issue and if anyone knows of robust aftermarket 9mm strikers. Thanks.
