Rufus The Bum Posted March 10, 2003 Share Posted March 10, 2003 I have a S&W 629 "N-Frame" in 44Mag Which I'd like to convert to a 625 in 45acp. Aside from needing a new cylider assembly and barrel, it should work, right? What are your thoughts? Link to comment Share on other sites More sharing options...
Chriss Grube Posted March 10, 2003 Share Posted March 10, 2003 sell it and buy a 625 if that is what you want. The cost would be a lot cheaper. Link to comment Share on other sites More sharing options...
Patrick Sweeney Posted March 21, 2003 Share Posted March 21, 2003 You'll also need a new cylinder stop thingie, the one that sits on the frame, left side, lower rear of the cylinder cutout. The process goes something like this; Remove the cylinder, barrel and punch out the thingie. (I can't remember the S&W name for it.) Fit the cylinder to the frame and crane, adjusting for minimum headspace and no endshake. Then, fit the barrel for correct timing and cylinder gap. Finally, install and file the thingie to fit so the cylinder stays on the gun when you eject, but the brass and moon clip clear it. Then, do all the customising you'd do to turn it into a match gun. Unless you're doing the work yourself, or get the parts real cheap, a new gun is a better path. Especially if you just sell the 629 to finance it.

2alpha Posted March 21, 2003 Share Posted March 21, 2003 The cheapest way would be to rebarrel and have the 44 cyl reamed to 45 but I still think sell it and buy a 625 is the way to go. Link to comment Share on other sites More sharing options...
Jeffro Posted March 21, 2003 Share Posted March 21, 2003 Rufus, Have to throw my hat in with the others....... I've been there and done that. By the time your are done, you will have way too much invested in the piece. And as an added negative (check this out with a gunsmith), I was informed that the .45 Smith and Wesson cylinder shouldn't be used with heavy loads, as the outer chamber wall is too thin. I am NOT a gunsmith, but I was told that by more than one source. Just sharing the info that I received. HOWEVER, do check out the strength factor on the cylinder............ don't want any accidents here!!!! Best, Jeff Link to comment Share on other sites More sharing options...
Patrick Sweeney Posted March 26, 2003 Share Posted March 26, 2003 The .45 ACP cylinder is shorter than the .44 Mag cylinder, so if you have the cylinder reamed and rechambered, you'll have to go with a .45 Colt barrel, from a 25-5. As for the thin walls, if by power you mean magnum level loads, yes, it is thin. However, the gun is plenty strong enough to stand up to a steady diet of Pin loads, 195PF-220PF.

kaiserb Posted April 2, 2003 Share Posted April 2, 2003 My vote is for sell it and buy a new 625. The 625 is very finiky for head space etc. making a 625 from a 629 would be a huge challenge Link to comment Share on other sites More sharing options...
