EMP 1911 slide sticks, won't return to battery.

    Hello, wondering if I can get some help with my Springfield Armory EMP 9mm. About 25-30 percent of the time, when I release the slide SLOWLY forward, it will stick and not slide all the way forward. I have to tap on the back of the slide, or the bottom of the magazine well to get it to unstick and go into battery. Now, I know what you are thinking "Just don't release it forward slowly". The thing is, every so often my EMP will fail to return to battery when shooting normally. I suspect that this phenomenon is the reason why. Can anyone give me an idea as to what causes this and how I can fix it? Here is a pic of what it looks like.


    Here is a video of the problem as well.

    If you can get it to continue into battery by tapping the magazine that may be your problem. I have had problems with after market magazines and even manufacturer mags, sometimes they just get bent or have a burr on them.

    The manual says, "Pull slideback and release slide smartly to allow slide to move forward and load a shell from the magazine into the chamber." (That's the instructions I found for the ESP on the internet... page 18.)

    Releasing it slowly, except when you're closing on an empty mag, is clearly NOT the way to do it. If the mag's empty you probably should release it slowly and nudge it closed at the end -- as that minimizes any possible damage to the extractor. (But empty, without a cartridge to chamber, it probably won't need a "nudge.")

    I don't think that is it, because if you look at the video the pistol does not have a magazine in and it still does this.

    Walt, thank you for the reply. Yes, I understand that releasing it slowly is not the way to go when normally loading the weapon. However the reason I found out that it does this is because I was having problems returning to battery when shooting normally. Ultimately, releasing the slide slowly is not what I want to be able to accomplish. I want to prevent failures to return to battery, which I think this is causing.

    When shooting, is the failure to return to battery accompanied by the nose of a bullet hanging up on the feed ramp? If so, I'd bet what you're doing here has no relation.

    You know, that's a good question. I can tell you this, the feed ramp is looking a little rough. Maybe polishing that up will solve it.

    Some EMPs, mainly early production ones I believe, have issues with the feed ramp that can normally be solved by either polishing or worst case scenario recutting the ramp. Springfield will take care of you either way.

    Awesome, I'll give it a try. I just so happen to have a can of Mother's Mag right here.

    Have you tried cleaning & oiling it?

    Put a dab of grease on the slide rails, barrel locking notched in the slide, disconnector notch in the bottom of the slide, and on the hammer cocking surface.

    Then shoot it some more till all the rough spots wear off.

    Yup, tried all that, to no avail. It already has about a thousand rounds through it.

    Is the slide sticky on the frame with the barrel out of it?

  13. OneSevenDeuce

    OneSevenDeuce Well-Known Member

    No, for most of the cycle it's smooth as can be, with or without the barrel. It's just that last little quarter inch or so.

    Sounds like a barrel link fitting issue then.

    The link may be too short, causing the barrel cam lugs to bind hard on the slide stop pin as it tries to lock up.

    Try putting the slide & barrel back on Without the recoil spring and slide stop pin in place.

    Then feel for the 'catch' as you ease it shut.
    If the catch is gone, the barrel link is too short.

    If it's still there, the locking cams on the barrel lugs are fitted too tight to the slide stop pin.

    Two fixes for that.
    1. Send it back for proper fitting.
    2. Or open up the bottom of the hole in the barrel link slightly with a round needle file if it's that?
    3. Or if it is the barrel locking cams, polish them slightly with a rubber Cratex tip on a Dremel tool.

    Thanks, will check that out.

    I just noticed that there are tiny burrs on the forward edge of the locking lugs on the barrel, like they have been rubbing against the slide just a bit too much.

    Well, that might indicate the barrel link is too long already and not pulling the barrel down away from the slide far enough!

    This might be a good cantidate for a trip back to the mothership and let them sort it out!

  18. OneSevenDeuce

    OneSevenDeuce Well-Known Member

    I think you are right.

    Update: I filed down the burrs on the locking lugs just to the point that my fingernail no longer catches on them. The problem is becoming harder and harder to replicate, so I think I'm on the right track. Thanks guys.

    Just to be sure that you understand - Filing them down will not eliminate the problem if the link is indeed too long or there is insufficient link down clearance for some other reason. It will only get worse until the source of the problem is corrected or it destroys the barrel and/or slide.

    The burrs are the result of the problem, not the cause. They are damage from the lack of clearance, not the cause of the clearance issue.
