    I have 4 1911's and on my Springfield TRP I have noticeable drag as soon as the slide comes into contact with the disconnector. I have never had a malfunction in this gun (with over 1500 rounds down range). I know Springfield uses MIM parts but my other two Springfield's do not exhibit this "sticky spot"... one is another TRP full rail that is smooth as glass, and a Champion Operator also smooth through the entire slide cycling.

    I am quick to understand the "if it ain't broke don't fix it" argument. However, I also am curious if there is a remedy to smooth it out. Again, its not a function thing as the gun runs 100% but if there is a way to smooth it out... I am all ears.

    Google Marvel/Disco cut, that is the answer you seek.

    You can first try polishing the bottom of the stripper rail on the slide. If that doesn’t work then a disconnector ramp on this part will fix this. Just had this done to a Dan Wesson and really like it!

    Thanks for the replies. The Marvel cut should be easy enough to do. I do think stoning the numbered engraving will help a bit but I would imagine most burrs have been eliminated by now with break in, but I'll check.

    Check the sear spring to disconnector contact.
    My sear spring tip was rough and sharp enough to gouge the MIM disconnector bevel.

    Even new Dan Wessons do this the first thousand rounds.
    Just shoot it.

    I mentioned I am already north of 1500 rounds in the first post, but thanks for the suggestion.

    My apology if that sounded snarky. Not intended. I actually sold that DW because of other issues with it not running right. The drag on the disco however did finally stop.

    Can you feel it when the gun is being fired? Or only when hand cycling.

    If the gun is running well, and it’s not noticeable while firing it, I’d personally leave it alone. The next thing you know the friction to move the slide rearward will be reduced and the timing / speed of the slide cycle may change. Then you might be chasing another thing to fix.

    I thought I wanted a short radius FPS once. It slowed the slide down enough to change the ejection pattern significantly . It wasn’t a big deal to troubleshoot . Just saying a lot of times a minor change somewhere makes a difference somewhere else. Ain’t no big deal if you can get it right, but taking metal off is permanent. Shoot the hell out of it, she’ll smooth out on her own and settle into her own equilibrium.

    Oh fwiw, I have doubts as to if mim parts has anything to do with this at all. I wouldn’t worry about it.

    On an unloaded gun, pull the hammer back, dry fire, keep the trigger pulled back, cycle the slide, then reset the trigger. See if you feel disconnector drag under these circumstances.

    Since the zip ties are already removed you can commence slide rackering.

    Shoot the bejeebus out of it and it will smooth out on its own.

    This is another one of those over-thought internet worries that people get. If you're really worried about it:
    1.) Stone the disconnector rail to a mirror polish
    2.) Polish the head of the disconnector
    3.) Polish the spade of the disconnector (both where it contacts the sear spring and where it rubs the back of the trigger bow) Don't forget to stone a tiny radius on the bottom edge of the disconnector.
    4.) Radius and polish the center leaf of the sear spring.

    Rob, do you also recommend to radius the bottom of the breech face? I noticed a pretty good radius on my NH and it’s smooth as butta!
