Default Brazilian Contract 45

Have a Brazilian Contract (1937) 45 acp revolver. While the screw is tight on the cylinder release button the part where the screw screws in is still sloppy. have had some thoughts about slightly shortening the screw a few threads to see if this makes a difference. It tight as I can make it but still sloppy. Works ok when you want to release the cylinder. I have an assortment of fine files take a little off each time and see if it made any difference. I'm thinking that the screw itself due to the maybe overly long threaded shank as it stands right bottoms out in it's hole. So any comments and or suggestions are greatly appreciated. Thank,Frank

The "screw" you are referring to is actually a slotted nut that screws on to a threaded post (hope this makes sense it's late or early lol) It is more likely the thumb piece itself is worn.

It is not unusual for a thumb piece to seem a little loose. It is movement of the entire bolt within the frame. Don't worry about it.

I agree. Don't screw with it.

First you must determine where the 'slop' is:

With the screw cap tight, pull up on the thumb piece and check for in and out movement. If that's the case, remove the nut. Frequently when the screw slot is cut in the screw cap, it leaves 'roll over burrs' inside the cap.
This is not uncommon.

Check for those burrs with good light and magnification. If there are burrs, it prevents the cap from seating the thumb piece tightly on the bolt underneath and makes it appear that the screw is too long. Chip off the burrs with a dental tool or small tipped screwdriver and replace the cap.

If no burrs in the cap, you're on the right track to shorten the stud. You can't over shorten the stud, the cap will still seat the thumb piece tightly. But the thumb piece may rub on the frame when tight. In that case you'll need to relieve the underside of the thumb piece.


Less common:
If the sloppiness is not the above and the thumb piece is tight to the bolt, it's a sloppy fitting bolt. Swing out the cyl, look at the front end of the bolt where it protrudes thru the hole in the recoil shield; is the hole oval shaped instead of round like the bolt tip? That indicates extreme wear.

Replacing the bolt with a new one may help a little. But when the cyl is closed you'll still have side to side play when the cyl center pin locks the cyl in the hole. This is not an easy fix. You can can have the hole sleeved or spot tig weld the worn side of the hole and clean up with a small, fine rat tail file. But not a real serious issue, because S&W has the front locking bolt and you can just ignore it.

Thank you all very much for all your comments and information. Ill dig the old girl out and double check. Thought the screw or nut was rusted in place because it was that tight. Put some kroil on it and let sit for a few days just to play it safe. Came out easier than expected. Again thank you all very much. Frank

I have 4 S&W revolvers in front of me. The thumbpiece on all 4 has a bit of play. Quit worrying -- it's normal.

You could try a small thin washer just as a test prior to shaving off the screw. It would be just a test and not meant for the small washer to remain there.
