    Default PM9 and accurate caliper request!

    The slide stop on my latest PM9 - the one that replaced the stolen one - is giving me fits of angst.

    Whilst firing, it performs splendidly .

    However, during the act of hand racking... I've found the nub that projects forth from the right side of the receiver appears to be subject to inadvertant pressing. The result being that the slide stop walks leftward, and the slide then locks, as the engaging surface on the slide stop interacts with the corresponding cut in the slide.

    I've already thinned mine.

    I cannot say how long the pin was to begin with.

    Currently, its 1.086 inches and seems to stick out more than I remember the slide stop on my old PM9j or on either of my PM45's.

    I think I may have removed a good .015 or so already!

    Can someone please, have mercy, and use an accurate caliper to meaure the total length of the pin from face of slide stop lever to its opposite side?

    Many thanks in advance!

    I believe the PM9 and CM9 slide stops are interchangeable.

    My CM9 slide stop pin is 1.1205, using my reloading calipers. (Center of the pin to the flat side)

    Yikes... that seems wide. I was thinking about taking another .020ish off mine, so it sticks out just barely past the edge of the slide on the right side.

    A long time ago someone who had excellent writing skills said to me: "Ask yourself 'what is it that I want to say?' Then, when you know what it is that you want to say, you are more likely to write it accurately and without ambiguity".

    Let me ask again then...

    Just how long is the PM9's slide stop pin supposed to be?

    In decimal inches please, to the nearest .002 is fine...!~

    My CM9 is-

    1.114" OAL (outside of lever to tip of pin) ( I believe the CM lever is a little thicker then the PM's)

    So maybe these will help more.

    .975" Pin only length (from inside surface of lever to tip of pin)
    .075" Amount of pin protrusion from frame on right side, assembled

    I had to increase the spring pressure on my CM9 slide stop when it was new to stop the pin from walking out.

    The slide stop spring also serves to hold the slide stop in place. The spring wire fits into the groove in the slide stop. The O.A.L. of the slide stop shouldn't have any bearing on pin retention. I'd look into adjusting the slide stop spring. Caution the screw that retains the slide stop spring threads into polymer. Do not over tighten.

    Yah Muggs... I know. I'm getting a good positive click when the slide stop goes home, its just that somehow, when racking, if I'm not careful, my fingers hit the other side of the pin, and it's just enough to get the slight caught up.

    If I'm careful... then I avoid the pin and it racks ok. And it stays put during shooting.
