I'v got a question for someone who knows revolver gunsmithing

Here the facts, I have a S&W Mod 10-7 revolver in .38 Special with a 4" prohibited barrel in slim contour & I wish to put a longer barrel to make it restricted only.

I found a barrel that I can have for a very reasonable price, Finish is correct so as the threads, force cone & the bore but plunger is missing & there is a obvious damage where the plunger is supposed to be. I mean by plunger is the spring loaded part under the barrel that latch with the ejector rod of the cylinder when you closed it. The damage is enough important that there is not cheap way to repair it to install a new plunger.

So my question is: Can I have this barrel installed & safely use my S&W revolver WITHOUT this specific plunger? & what it's exact purpose?

Any help appreciated
Thanks

It centers the plunger rod, and the shroud is to protect the rod. As long as you remove the guts, I believe you can use this barrel with few problems. You may have to relieve the opening in the shroud a tad at the plunger end, but seeing as how it's already damaged, that shouldn't be a problem. - dan
 
It's a S&W slim countour barrel for Military & police revolver so there is no shroud or rib only a kinda bump where the plunger was, the actual damage look like if someone oversize the hole of the plunger & try to install a larger diameter plunger, the hole is badly damage but nothing rip out that may interfer with the ejector rod

It's only avoid to install a new plunger & I wanna know if it dangerous to shoot a S&W revolver without this aligment plunger.

The barrel is cheap but not cheap enought if it scrap the gun!!!!

Many S & W model 10 revolvers were modified to a PPC style and many of these guns had a larger heavier barrel fitted. Usually the front lock you have mentioned was not used after that.
These guns fired thousands of rounds in heavy match use and show no problems.
We have one at the shop. I will examine it tomorrow and see how the front of the cylinder is secured!
Remember, Colt revolvers never locked up the front of the cylinder...ever, but they do turn in the oposite direction.....

What m39a2 says is correct - the cyl. is then locked by installing a detent(s) ball into the top of the crane to meet up with a detent placed in the appropriate location in the frame. I have one with 2 detent balls installed that is a VERY stong lockup. It is important that the cyl. alligns properly. It can be a fussy job to do this and requires someone who is experienced with the process. Having said that it should be about a 25.00 job from a knowledgable smith.
 
Caporal - if you want to give this a try yourself you will need a drill press, a 1/8 SHARP bit, prick punch, center punch, magnifying glass, detent ball, detent spring and staking tool. I would be happy to provide a spring, ball and staking tool (as well as printed directions). Let me know and I'll get them into the mail for you.

Best regards - Gus
 
jaydeee[/b], Hi, I see that you are a retired S&W gunsmith and have a question for you. I bought a 1905 Smith & Wesson Hand Ejector in .38 S&W and want to know if I can get a cylinder chambered in .38 Special for it. I don,t know until I get the paperwork what model ( 1st,2nd,3rd or 4th ) but I realized that .38 S&W cases and diameter are slightly larger but I do know that a lot of Victory Mdel .38 S&W,s were rechambered for .38 Special and sold after the 2nd World War. Can you enlighten me? Thanks, Alex.

You can re-cylinder these revolvers you should not rechamber them!!!!
A lot were rechambered, it is not a good idea due to the case differences.
.38 S & W is a neat old cartridge and these revolvers are getting rarer and rarer all the time, especially in issue condition. I would suggest leaving it as it is and buying another .38 Special. Seem to be lots around. Do you have prohib status?
