Hello, like you I am a fan of the 45 acp for SD. Sorry to hear about your problems, my G36 has been 100% since new. My round count is close to 1k now. Do you think the +1 mags could have a negative impact on reliability? Not sure, I have never used them. Hope it gets better. For me, the G36 is great for ccw.
