Widder, SASS #59054 Posted March 15, 2022 Share Posted March 15, 2022 I've got a 1911 that the slide hold open lever is prematurely locking back the slide while firing. What causes this and how can I fix it? ..........Widder Link to comment Share on other sites More sharing options...
Rip Snorter Posted March 15, 2022 Share Posted March 15, 2022 Kuhnhausen, The Colt .45 Automatic Shop Manual, has a short list - Magazine follower issue (use a round top follower), or plunger & spring (replace). Haven't experienced the issue personally. Link to comment Share on other sites More sharing options...
Hendo Posted March 15, 2022 Share Posted March 15, 2022 Does it do it with every magazine? Does it happen randomly or with a couple of rounds left? Link to comment Share on other sites More sharing options...
Pat Riot Posted March 15, 2022 Share Posted March 15, 2022 Is it an extended slide stop? I found my thumb knuckle was bumping my extended slide stop when shooting and locking my slide open. That was after testing, cleaning, lubing everything, trying new magazines and cussing at it profusely. It turned out I was the cause. Link to comment Share on other sites More sharing options...
Widder, SASS #59054 Posted March 15, 2022 Author Share Posted March 15, 2022 Thanks for all the replies. But I think I found the gremlin. The inside section of the slide stop appeared to be a tad larger than necessary..... and the bullets in the magazine were slightly rubbing against it, causing some minor upward pressure. After about 4-5 rounds of minimal upward pressure from the bullets rising in the magazine, it became enough to cause it to lock open. CURE: I slightly polished the area which rubbed on the bullets and eliminated those close tolerances. I'll probably head out on the farm tomorrow and test the results. Thanks for the input. I also found some good information on YouTube. ..........Widder Link to comment Share on other sites More sharing options...

I've owned and shot MANY 1911's. This particular one is new with less than 50 rounds. Some full mags would run great. Then trying some other bullets, I experienced the slide lock popping up. I didn't have a clue till after I posted this thread. Then I started checking out some YouTube videos and a couple of them spoke of this situation. Sooooooo, I checked it out on mine and sure enough, that seem to be the issue. ..........Widder Link to comment Share on other sites More sharing options...
