Top Break 44 Russian DA won't remain cocked

[klambo]

Hi All,

I was giving a 44 top break (not the prettiest) with a problem remaining cock, a slight bump on the hammer and it releases.

DA seems to work ok. Not the smoothest action, but functions.

I can't find any illustrations or pics of the assembly, so I'm not sure if it's correct.

Any thoughts or pics of a top break with the side plate and trigger sear would be appreciated.

Thanks

I would start by removing the grips, and giving the gun a good flushing with some break parts cleaner through every opening while working the action then a good oiling through the same. This may solve the push off problem you describe. If this doesn't cure your problem the next step would be to investigate the trigger, sear, hammer engagement.

Flushing out the mechanism is a good start. Please resist the temptation to file the sear contact areas. Filing will mess up the whole geometry and timing of the revolver. A very light stoning of the hammer sear and its partner, the rear sear may improve the hold. Light stoning, proper stone and proper angle can't be stressed enough.

And I would start by looking at Chocoine's Antique Firearms-Assembly/ Disassembly book which is replete with schematics of a whole bunch of old guns, including yours. So much for getting it apart and back together----fixing it is another matter altogether. For that you'll want Chicoine's Gunsmithing Guns Of The Old West. As an alternative, you may wish to send it off to Chris Hirsch----a gunsmith who works ONLY on antiques, and who, I dare say, can fix ANYTHING. [email protected]

If you are not familiar with firearms mechanical functions please resist to go no further than a good solid cleaning as was mentioned by Mike. A can of brake cleaner should suffice, give it a good solid spray, take a toothbrush and try to get into any crevices, spray again and repeat until the can is finished.
While working the cleaner around its OK to work the mechanism to get any schmutz caught between parts. Spray everything out with air pressure and lube with something light, like Breakfree. If it still does not function properly and you want to have something more than a curiousity send it off to a compentent old Smith mechanic as mentioned above.

I should have added when I received the gun it was already disassembled, so when I reassembled I did a deep clean prior.

I will look into the assembly/disassembly book, maybe I got something wrong?

I don't want to touch the hammer or sear with files etc. Just don't know enough to do any metal removal.
