m28 conversion to 45 colt with 45 colt cylinder and barrel

I am thinking of converting one of my old beater M28s to 45 colt using a 45 colt cylinder and a 4 inch 45 colt barrel. Anyone had any problems with this conversion?

Why use a Colt cylinder when you can purchase un-chambered M28 cylinders with the correct ejector plate cut for a Smith, the cylinder stops are cut for the Smith...just chamber, barrel and shoot. See the Classified section and save your Colt cylinder.
BTW: These cylinders are unfluted, making them much stronger than the standard fluted S&W cylinders...you can work up some pretty potent loads for the venerable old .45 Colt cartridge...even triplex loads.

Silhouette, you may have read Thomas's post incorrectly--but it's easy to see why, it's almost like the Abbott and Costello 'Who's On First?' skit. Let me see if I can maybe straighten this out...

Kinda thinking Thomas was planning on using a Smith and Wesson-made barrel and cylinder that are chambered for the .45 Colt cartridge. That is this caliber's proper name, even though some makers still call it ".45 Long Colt". And maybe because of the mixups, they still should. Can't tell you how many times I've had to explain myself when referring to a .45 Colt versus say a .45 acp.

Let's see....I understood Thomas to mean he was going to take a M-28 S&W and put a Colt cylinder and barrel on it. Which didn't sound quite right because of barrel threads and reverse cylinder rotation...so I suggested using an S&W cylinder and chamber it for the .45 Colt. The word "conversion" and reference to a Colt cylinder and barrel threw me. (I agree on the naming convention...there is no such cartridge as a .45 Long Colt) LOL!

Thomas...what do you mean!!!!!!!!!!!!! LOL!

Now I understand the comments.

You two had me really going. I didn't follow the comments at all until Sillouette answered again. "Who's on first". Both the 45 colt cylinder and the 45 colt barrel are off an N frame Smith. I got them many years back when you could buy stuff like that on ebay and bought them right. I have done a similar change "not conversion" to some M28s making them into 45 acp and this worked out ok for me with a little tweaking of the tuning. I was just asking around to start some conversation to see if there was something I might have missed in the thought process. Thanks to both of you for responding.

Thomas, I apologize...I'm a bit slow on the uptake sometimes! LOL! So, you have an S&W barrel bored for the .45 Cold cartridge and an S&W cylinder chambered for .45 Colt. If this is the case, it should be a breeze. The only pitfall for a weekend pistol smith is if the barrel, when screwed in, does not allow the front sight (or rib) to line up with the rear sight line. If this happens, put the frame in a wood padded vise and use a 2 foot section of 2x2 to slip into the cylinder gap and add force...stop if you see it won't line up...you don't want to warp the frame. The barrel will have to be turned on a lathe just enough to remove some of the barrel from in front of the threads so it will screw in far enough when pressure is added. JUST A HAIR! You may need to take the same amount off the butt of the barrel (forcing cone area) so it doesn't rub against the cylinder face. Pin the barrel and your done with that. If the cylinder came from a model 28, the timing should be good...of course the cylinder advance arm may need shortening a hair....or you may need a longer one (new). Of course you could replace the extractor star...but that takes more fitting. I hope this helps.

Thanks for the vote of confidence Sillouette. I had to take a bunch off an S&W 45 colt barrel that I used on one of my 45 acp guns from the M28. Had to do that to get the cylinder barrel gap into specs.

Conversion

That will work. I had Travis Strahan do one on my M28 back in the 70s...You will have to buy a M-25 cylinder stop but it i fairly simple them to convert and time up a .45Colt cylinder.

This 45 Colt was originally a beater old M29 that I had rechambered and an 8 3/8" 45 Colt barrel I had cut to 5" and fitted with Stroh's interchangeable front sight. Jim Stroh did the work including narrowing the hammer thumbpiece and trigger and having them re-CCH, polish and blue. I went the rechamber route as I had him chamber it with a minimum spec reamer.
