1917 Cylinder Swap

Excellent as usual, Thanks

Mark thanks again for the great presentation and insights in doing things correctly. I believe that I know my limitations and you are the man in proper gunsmithing. Great job.

You can smell the sizzle...J frame not withstanding, he does succeed in getting you into the S&W frame of mind, me thinks

Had to laugh when I saw the book cover. I finally sprang for Kuhnhausen's book a couple months ago. Disappointed in how little specific J-frame material it contains, but if you want to fry your mind with how to fit a trigger, cylinder bolt and hand, this is the book that'll do it.

I had one of those, Colombian contract. The trigger was heavy, especially for a long action Smith. I read somewhere the ACP guns were designed that way to insure reliable primer hits with springy steel half moon clips. Compared to the 1917 Colt, it was stagy, uneven and much harder to run double action with acceptable accuracy.

Wow Mark. That was a great one. Thanks

As someone who who hasn’t gotten into the guts of a revolver, I found this VERY informative. I really appreciate how you let things happen and share your thought processes facing those things. Critical thinking is the take away here, not just showing us “the answer”. Thanks, Mark.

Tefloned' to cover the heavy buffing it received. It is still super tight, so much so that it will go into 'stacking' sometimes in double action. Love your work.

Many years ago I bought an 'almost' 1917 Smith. It is one that was built from parts by S&W on South American Contract's in the 1920s. It has seen a hard life and was

I buy the modification theory. Long colt runs in this cylinder, however I didn't mention that because it would have fogged the issue

I think that original cylinder has been modified. From what I remember reading if it had been one of the originals that had been straight bored through, then it would be just that and there would be no lib anywhere in it so .45 ACP carriage would fall completely through the cylinder and fall out. If there is a lip in there I believe that indicates it had been modified by reaming out the original lip a bit at some point so you one could feed .45 LC in it. I have one that's the same that was sold as being chambered for .45 ACP or .45 LC. which it does though the rim of .45 LC isn't really thick enough so the primer winds up with some really deep hits.

One of my dream gats. Thanks Mark.

As someone who carried a S&W model 10 as a rookie, this was fascinating. Thanks
