Thread: Question about slide stop spring...

  1. #11

    Default

    Hi,

    I put the screw back in just to where I see it not touching the slide stop (a little light can be seen). In this spot it also doesn't seem to impede the spring from moving either. I noticed a little wear on the end of the screw where it has been rubbing the slide stop, so maybe this was part of the issue. I greased the screw head to smooth it as well as the slide stop pin and the barrel center, all greased with flitz grease. It does seem to have a stronger downward push now than it did before. If you push it up and let it sit it will try to move down slowly on its own and it you retract the slide (removing pressure on it) it will jump down with a small snap, so hopefully this will solve the issue. An empty mag does indeed push up on it properly as well.

    Thanks,

    Alan

    Here are some pictures and the discussion about my PM45 slide lock spring. I got my P380 back with the random slide lock backs before the magazine was empty.
    Kahr replaced the slide stop spring and polished the slide stop. I don't have pix for those but try these from my post on 07-19-2010, 09:20 PM :

    Look at the springs... old vs. new and how the spring should rest on the "ledge" on the inner side of the slide release.

    Wynn, you da man. That was the exact thread I was trying to find. Your darn good at hunting this stuff up. If it was up to me I'd give ya a promotion but since I'm low man on the totem pole you already outrank me.
    Perhaps a gold star would suffice, thought that counts and all that?

    Hi wyntrout,

    I read that whole thread - are you guys saying that the screw should be tightened until the washer flattens against the spring? I found that when I did this that the entire spring did not want to move, just the end of it. I figured it should be loosened just enough to allow the whole spring to move under the washer - is that right?

    Thanks,

    Alan

    Your precisely correct Alan, the spring needs to move. I also recall a fella that had that washer intefering with things and he just flattened one side a bit to clear. Your on the right track if that lever is pulling down and moves freely.

    Hi,

    It certainly seems a bit more positive now, we'll see how it does the next time I get it to the range then. Thanks for the help everyone!

    Thanks,

    Hi,

    Well, I took it out for another 50 rounds today and it failed once! I guess I'll call Kahr tomorrow and get them to send me a new spring and see how that does.

    Thanks,

    Alan

    Ask for a spring, washer, and screw to make sure you have a good fit. I was told to just tighten until I felt resistance. You don't want to strip the plastic screw hole. That screw spring needs to move a bit... the little part that rests on the slide lock.

    Hi,

    Well, so far, they have been reluctant to send me a new spring to try. I've gone back and forth a few times in email exchange and they said they wanted me to send it in which I really don't want to do unless I have to. I'll try to get them on the phone tomorrow. What else besides this spring could cause an issue like this?

    Thanks,

    Alan

    Hi,

    They are sending me a new spring to try. I also called tech support to get the proper way of setting the screw and they said:

    The spring looks somewhat like a G and that the screw should be tight enough that the top and left part of it do NOT move. If I understood him correctly, the bottom perhaps from 6 o'clock and going counter clockwise should move and that the rest should be clamped down.

    My question is - for any of you who have one that is working great. The next time you safely unload and field strip it, would you try pushing down on the little part that contacts the slide lock and see if only the 6 o'clock through 3 o'clock part of the spring moves, or does more of the spring move? This would confirm what the tech said.

    Thanks,

    Alan
