(And, it did indeed leave a very obvious 'track' on my slide.)įor what it's worth: To evaluate the areas of contact, field strip the pistol and remove the trigger and trigger housing assembly from the frame. This 'gotcha' also wears as the slide cycles, allowing improved operation and reliability over time as well. but not quite enough to prevent reliable operation. such that the adjacent frame rail was (very slightly) binding the slide. Brass to the faceĪlso, in one of my Glocks, I found that the connector reset tab was not bent at a true right angle and was pushing the slide 'up'. The above also seems to 'fit' with this recent post. With use, as the slide is operated, the 'offending' edges are worn away and the pistol functions more and more reliably. To me, that also explains why the ‘problem’ is intermittent, as I’m confident that the slide moves very slightly differently with each recoil. To make a long explanation short, it has to do with how sharp and/or ragged the edges of the stamped frame rails are and how much they drag on the slide. After further study and 'thought', I evaluated some of my pistols and believe I now understand why some polymer pistols may, in fact, benefit from a break-in period.
and it implies that at least some pistols do indeed need to be broken-in. However, I've discovered that your post represents a common observation presented in numerous forums. That being said, in my experience, the most common 'fix' is technique.įor years, I’ve supported the position that polymer pistols don’t require a ‘break in’ period. However, to your point, it's indeed possible that the extractor, extractor spring assembly, and/or ejector need to be replaced. Historically, many have complained about firearms that are actually in good working order. and they had to master good technique to shoot well. And, while easy on the hands and arms, the low PF 9s required absolutely perfect technique for the pistol to function properly. When teaching my grandkids, I developed some very low power factor (low recoil) 9mm Luger 'training cartridges' for them to shoot. (To me, a 'soft cycle' occurs when the case 'wimps' out of the ejection port, generally in the direction of the shooter.) It's just easier to 'short cycle' or (what I call) 'soft cycle' lower power factor cartridges. But, it's not really the cartridge's fault. In my opinion, that's why 'weaker' 9mm 115 gr cartridges tend to get a 'bad rap'. Hotter cartridges tend to 'compensate' for some marginal techniques. Your observation that 10s are 'hotter' than 9s is precisely my point. Click to expand.My apologies if my posts seemed 'snarky'.
