Cylinder stop on K-22 Combat Masterpiece - I need some advice!

[THREEDFLYER]

Hello all,

I picked up a super clean K-22 Combat Masterpiece in 98% condition and i have one issue that needs to be addressed.

The gun has seen little use, but a previous owner had gotten a littel carried away polishing the cylinder stop.

I am able to physical rotate the cylinder out of the stop with not too much effort.

My solution would be either to have it replaced with a new one OR attempt to correct the problem with the existing part.

The stop is just a touch short and the edges have been rounded a bit more than it needed.

Suggestions?

Tom

If it is that goofed up, I'd get a new part.

You can always resort to a new cylinder stop but it's unusual not to be able to re-fit the existing cylinder stop a lot easier than a new one. Because a new cyl stop may need some fitting where it contacts your trigger as well for proper timing.

The cylinder stop spring may be weakened or the screw in front of the trigger guard that holds the spring in may not be tight or may be too short.

Then I would determine if the stop is engaging full depth in the notches. Coat the bottom of the cylinder notches with a black felt pen, then cycle the cylinder around two or three times in SA, lowering the hammer manually each time you cock it.

Now look in the bottoms of the notches for contact marks. If none:
1. Remove a little metal from the stop where it contacts the frame at the bottom of the opening so the stop will rise higher in the frame window.

2. If there's contact in the bottom of the notches, square up the edges slightly and see if you can still turn the cylinder when locked.
If you can, do step 1.

You've got nothing to lose by trying a little fitting because you can always resort to installing a new stop.

Similar situation

I just replaced one on an old 38-44. It was challenging to get the timing back in order with the new piece. I broke the first replacement, they don't bend AT ALL, cast metal I guess, very hard.

There seems to be quite a few working surfaces with relationships to the timing on one of those little buggers. I think I was lucky in that it turned out OK on my second piece. I might opt to have a pro do it next time or get some more instruction before I attempt it again.

Hondo, what is this "bolt" you speak of and why didn't I install one? Is that the pin that fits into the rebound spring block. If so why do you need to replace it when you replace the cylinder stop?

Thanks, Pete

Pete, the word 'bolt' for cyl stop accidently slipped in there. Thank you for the heads-up, I have edited it for clarity. I shouldn't be posting that late at night!

I'm with Jim (hondo) as to just "normally" refitting the cylinder stop, to the gun, ( don't quite understand his "bolt", trigger relationship???)
anyway, not that hard to redo/fit the 'stop' and at worst have to replace its 'spring'.............
hard to know/tell exactly without "seeing" it and how it fits and what was removed/polished, let alone what exactly did they do "inside" (out of sight), to the 'stop'..............

This is the part of the post that is of concern. Assuming this is true, he is better off with a new part. If the stop is rising all the way up and it is too short, it needs to be replaced. If the stop's edges are too rounded off, it won't bear properly in the cylinder notches and needs to be replaced.

Stop

Thanks all,

I removed the stop last night and honed the top of it very slightly to see if I could get it to rise a bit. But I did not take enough off to make a difference.

I believe the stop has been taken down too far to be salvaged.

Now to decide if I should order a couple of them and try the repair or send it out to be done by a competent smith.

Where does a guy find these parts?? I also need some S&W side plate screws for a K-Frame.

Hi Tom,

I suggest taking it to a gunsmith. He may have parts or can get parts if needed. Google Poppert's Parts of Chicoine for screws

If the stop is not contacting the frame below its slot when fully in the up position, the trigger-to-stop fit may not be allowing it to rise fully. It's all about observing the geometry of the moving parts.

Good luck and let us know how it comes out,
