I finished my Polymer 80 Glock 17 build over the weekend and took it to the range today. I brought with me a set of cast loads to test and a handful of factory fmj's to start it out with a function test.
Problem arose first time I pulled the trigger, failure to eject and the slide did not go into full battery with the empty still in the chamber. I clear it, and the next one ejects fine, but the slide hung up defore going into battery again. Push the slide forward with my thumb, and same thing again, and again, and again for all 10 factory rounds. There was 1 stovepipe and 1 failure to feed.
Any ideas as to the cause? Any time I rack the slide it closes up tight, but under recoil it has stopped a smidge short 10 out of 10 times. Thanks in advance.
