[QUOTE="cmeilahn, post: 3685284, member: 49725"] I agree about the pins and the jig. The jig is (1) a pain, and (2) not very precise, and the result is the pins don't always line up well. My next 19-ish build is going to be a Lone Wolf. On this build, I used a hand drill per the build instructions. On my subcompact build I used a dremel & press. The pin holes in this one are rougher, but still line up fairly well... though not 100%, for sure. The rear trigger housing pin & rail assembly setup were a bit off. I tried replacing the P80 plastic recoil spring assembly with a stainless one from Rockey Brass with the standard OEM spring strength. It didn't make much impact, but did identify another issue... I had a bit of a nik in the recoil spring channel. After I smoothed that out, it stopped catching. I may get a higher strength recoil spring, but I'm not convinced that's the problem. However, it is a bit smoother with the original and the replacement seems a bit off. I tried a few different extractors, including the P80 one that came with the slide, an OEM gen3 extractor, and a Rockey Brass failure resistant extractor. All have the same result. I upgraded the ejector from a gen3 to a gen4, again with no change... but I did that before the first real shots and I wouldn't expect a change to slide closure from the ejector, just the extractor. My suspicion is with the springs. Specifically the firing pin safety spring or the extractor depressor plunger spring... possibly the extractor depressor plunger & bearing too. In the case of this build, I only have about 60 rounds through it so far. And the issue seems to be getting "worse". I want to get it figured out without spending too much more, but maybe a full set of new springs would help. [/QUOTE]
