Extended slide stop creation for P85 MkII

I dropped hammer on an original style slide stop off of Numrich last night:
849300 Slide Stop, Early Model, Blued http://www.gunpartscorp.com/Products/849300.htm

Roylt did a heckuva job on his P89, installing an early extended stop. http://www.rugerforum.com/phpBB3/viewtopic.php?f=2&t=213631&p=2138319&hilit=P89+mod#p2138319

The MkII stop is thin, the serrations are on the top, and the stop is short... My right thumb cannot sweep down on the current stop without rotating the pistol in my grasp -or- using my left hand... Sorta defeats the potential...

The idea came up of adding more metal stock to a current slide stop so as to enable the creation of a fuller and longer stop akin to those on a 1911. I undestand that such a stop, being larger, may snag on a holster. Got it. That is supposedly why Ruger redesigned the original stop.

The extra metal might be added via TIG, brazing, or adhesive. TIG and brazing have lots of heat, the stop is thin, gotta be careful. Adhesives just do not fill me with confidence... Let me run the slide forward... snap... ting! (as the extra metal hits the floor)...

A last possibility is machining... use screws to attach the extra metal....

As of right now, the early stop is as far as I am going to go. But for you all looking for the next thing for the P85, have at it!

Keep the P-guns alive!!

So... how does the slide stop come out of the P85? Got it, just gently pried up on the end of the retention spring and it slides out, easy-peasy.

Trigger will not sit down far enough to allow the stop cross pin to ride over it. When I try to mate the slide, it will not go past the end of the frame - think of racking the slide back to chamber a round... Breech will not even begin to open.

Hmm, no trigger in P85, slide stop cross pin clicks into place, no suprise there. Fits over top of trugger bar, fits the milled cutout in the top edge of the frame perfectly.

Got the trigger bar plunger aginst the trigger bar

It appears like the trigger bar position may be the crux of the matter. With the bar foreward, the trigger rotates on the angle and the slide stop pin can go home.

I'm not sure I follow. Are you asking for help?

The trigger spring has to be pushed in to get the trigger and trigger bar to seat. If that is what you need help on.

Berettapistols did a complete tear down on a P89 which is the same. Search here and you should be able to find it. I learned a lot from that way back.

Not good, having your lone pistol refusing to be re-assembled... Got r done...

First, the parts involved don't exactly do what their name implies.

I assume you have safed the pistol, removed the slide, and the trigger needs to be mounted back onto the pivot sticking out of the trigger bar. The trigger bar spring is not under compression IF the trigger is not installed...

In short, I drove out the Slide Stop Spring Retainer. That is the little 1/16th inch pin abut 1/2 inch in front of the slide stop. Drive it fom outside, inward. It is not spring loaded, it just lays there in the link channel of the frame. Take it and put it in a container. Now take a heavy needle, and get under the front "hump" of the slide stop spring.

This is what actually retains the Trigger Bar Spring Retainer, that little pin end you see peeking out of the front of the frame, just above where the forward end of the trigger guard melds into the frame.

Now the trigger bar spring retainer will stick out of the frame about 3/16ths of an inch, and it holds onto the trigger bar spring... Carefully pull the retainer, spring, and trigger bar plunger out the front of the frame, set into container.

Now mount the trigger on the pivot, place in the trigger cut-out. Stick the slide stop into the cross hole. Take the Trigger Bar plunger assembly out and re-insert into frame. Now the trigger bar is not maddeningly riding above it...

While holding the trigger bar sprinng retainer in with your thumb, take the slide stop spring out and re-insert the 90 degree bend und down into the vertical hole. Jiggle things around until the spring tip fits into the groove around the trigger bar spring retainer. When fully seated, the top of the "hump" is below the top edge of the frame.

Now this goes better with the P85 in a vise... Take a thin bladed screwdriver, press down on the slide stop spring until it is below the hole for the slide stop spring retainer, then tap the retainer in.

Now pull the slide stop out until it catches the wire spring. Put the slide back on. While holding slide back, put slide stop in all the way. It should work, now. Before doing a function check with a snap cap, remember to rotate the ejector up inside the magazine well.

Works for me.

Re-read my post detailing the successful re-assembly. I tried pushing that plunger in (many times...) with a small flat bladed screwdriver, I got the trigger on the pivot down into the frame , but it was incorrectly positioned. That is why I pulled the TBS assembly, then everything worked.

Be nice if someone had a P85 shop manual... Unobtanium...

If I could post images, I'd show the orientation of the trigger bar retainer, the spring, and the plunger. The one post I think you mention with disassembly images comes up as HUGE images...

Whatever.

Not real sure why you had so much trouble getting the trigger back in the right place.

This is the post I mentioned.

Sounds like you got you 85 running again though.
