My pistol has a slide stop that will work itself out from time to time and jam the gun. I can get it back into action by gently tapping on the slide stop with a rubber mallet but it is disconcerting.
Has anyone else had this problem?
Is there a way to fix it?
I did notice on the slide some rough spots on the inside near the slide stop notch, should I polish/remove those?
Thanks in advance.

Also does anyone have the link to the proper method for polishing the feed ramp?
Looks like mine got a small nick in it last time I went shooting.

I'm no expert, but I wonder if you put a new spring and detent in the plunger tube, if it would put more tension on the slide stop and help it stay in.

Did your slide stop stay in before and now this problem has suddenly developed?



One real safe way to polish your feedramp, without worrying about messing up the geometry, is to use some Flitz on a soft rag, and your finger.
It might need to be re-done from time to time, but after you polish it real good the first time, it's real easy to touch it up.

Another way, is to use wet-dry sandpaper. Start with like 400-500-600 grit and work your way down in grit a couple steps. (up in number)
Like start with 600, then use 1000, then use 1500. Then use the Flitz. But you have to be very careful not to change the shape of the feedramp.
Your not really trying to remove material, just trying to polish it.

I think I found some tutorials once by searching 1911 feedramp polishing, on dogpile.com

Nope it was always that way, before I shot 1 round out of it I was showing it to a friend. I thought he accidentally pushed on the pin side of the slide stop because he has very large hands, but then it happened to me and another friend while out shooting.

Is there any way the slide stop pin could be undersize? (loose in the barrel link)

the slide stop is held in by the plunger in the plunger tube. either the spring or plunger is weak/off spec or the slide stop does not engage it properly due to off spec slide stop.

Now that I look at my first post again, if you use the wet-dry sandpaper to polish your feedramp, you might want to start with like 800, or 1000 grit and work your way down in grit about 3 steps. (up in number) I think 600 might be too coarse to start with (depends on how bad of a ding you've got in it).


Too, I was wondering what brand pistol you have, and if it has a warranty. Or if it was made by a company known for helping out customers.

If you really just want to fix it yourself so you don't have to send it out and wait (I don't blame you) I would start with the spring and detents in the plunger tube. (make sure they're facing the right direction via an exploded view, because both detents are different) That's the cheapest and easiest fix that it could be. If that doesn't fix it I would then try replacing the slide stop. They're not too expensive either, probably like between $25 and $40.

Once again I'm no expert, but that's what I would try first.

Hope you get 'er up and running soon.
