So I took my new build to the range yesterday. Good news was that it fired. Bad news is that it will only fire one round at a time. Sometimes it wouldn’t extract the spent case sometimes it wouldn’t. When it would extract the spent case, it was having an issue going back into battery. The lip of the case would get caught on the feed ramp. I have an aftermarket slide with tons of lightening cuts, 3 windows, and an RMR cutout (didn’t run with an RMR). I have an aftermarket stainless non captured guide rod from primary machine with an OEM equivalent spring. The issue IMO is that the spring my new too heavy and there is not enough weight - keeping it from going back far enough. My question is, should I go with a lighter spring, or is that not my issue?
