several questions re the slide stop
I am having trouble getting the slide stop to go in in that the spring loaded pin will not go in , on its own ,to butt against the slideplate assembly. If I am able to push the spring loaded pin in with my fingernail while reinserting the stop, it butts against the slideplate and goes into place like it should.
I removed the slide stop from my 4567 and it butts against the slideplate when inserted on the 4506 w/o having to push the pin in.
In looking at the 2 stops, it appears that the spring loaded pin on the stop for the 4506 is a fraction is a fraction longer.I put a couple drops of oil on the pin on the 4506 but the pin will not retract enough for the stop to "snap"into place against the slideplate w/o pushing the pin.
the 4506 has been shot >3500 times
Does anyone have an opinion as to why this is happening?
Also, what is the slidestop pin on the slidestop. It goes through the stop.
Am I correct in thinking that the slidestops on the 59xx, 45xx, &10xx series are the same?

Not uncommon.

Minor variations in tolerance and fit in the different combinations of assembled guns (frame, side plate, slide stop assembly, guide rod, etc) can be involved in how/whether the little plunger clears the outer edge of the side plate during assembly.

Personally, having owned a couple of my own 3rd gen .45's, and having carried a couple issued ones, and having supported a fair number of them (including new production 4566/4513TSW's), I've experienced that more often than not, the lever's plunger has to be lightly depressed with a thumb nail to clear the edge of the sideplate during reassembly.

My own original 4513TSW & CS45 usually require the plunger being slightly depressed to complete installation of the slide stop assemblies. I'm surprised when the levers go in without having to do it.

Not sure what part you mean. The "pin" is the round pin that is inserted into the frame, against which the guide rod plunger rests.

The "roll" pin in the rear of the lever body is what holds the plunger & plunger spring inside the end of the lever body.

There are different slide stop lever assemblies designed to fit the various single & double stack frames (the body pin being appropriate for the frame width is one important factor), and there have been revisions throughout the years involving finish, plungers, lever shape, etc.

Shorten the plunger pin slightly and your problem will be fixed.

Thanks for your reply Fastbolt-Only recently have I had to depress the plunger to get the slide stop to go into place against the slideplate assembly on the 4506.
I think what I was calling slidestop pin, you are calling the roll pin. I was thinking that it held the plunger and plunger spring in place. I went to numrich to get the name of the 3 parts that go into the slidestop since it is easier than going to S&W website.
As I was saying, my 4567 and 1006 "snap" into place against the slideplate assembly w/o any manuliplation of the plunger. I am not going to be concerned that something is going wrong.
Thanks again
