I recently purchased a brand new G 36. Shot 300 rounds through it, no malfunctions. Did notice the rear housing pin would creep to left side pretty bad after 100 rounds. Called glock and they sent me a new pin (think the problems solved). Took it out again had two fte and one failure to feed.Also noticing that empty mags aren't releasing without me manually pulling them. All of these problems seem to be common with the 36. I really love the ease of carry but is it worth dealing with glock to fix or should I just take it back?? Wanna kill these ads? We can help!
