View Full Version : Non-ported compensator for S&W 500 Mag?

November 6, 2007, 10:34 AM
Smith & Wesson offers a non-ported 'end cap' for the 460 magnum. I have often wondered why something similar is not offered for their 500 magnum. A brave (crazy?) soul on another forum modified a 460 blank to fit his 500 magnum (see below - edited).

This is how I did it:
Face the back of the compensator . . . a little bigger at .550 inch. It locks up snug in my revolver and it looks factory but it’s not!

He seems to be happy with the results, is still alive, and has all his fingers. Any thoughts from you Smiths?

Enlighten me - how are the 500 Smith bbls secured - are they "tensioned" like the Dan Wessons were - or?

I was not very clear . . . here are some picts that should help explain. He purchased the blank compensator made for the .460 Magnum (made by S&W), and had a gunsmith or machinist make a few changes to fit his 500 mag. He only machined the insert, no barrel modifications were made. The blank 'end-cap' (as S&W calls them) is attached via the allen screw like the original.

Would you shoot this thing?

Thanks! Evidently the 500 bbl. screws to the frame in a normal threaded way and the end configuration is fastened another way. That's a pleasant suprise. I had thought it was a tensioned bbl. like Dan Wessons were.

I was wondering about this exact thing and found this thread googling.

I want to try firing my S&W 500 8 1/2" without the compensator but I think the muzzle blast may wear the protruding portion of the barrel shroud. This 'end cap' is exactly what I need. Any news on whether S&W ever offered one for the 500? I don't know why they would make this for the 460 and not the 500.

In case anyone's wondering, the reason I want to see if I can handle this cartridge without the compensator is mainly out of concern for my hearing. I read somewhere that even with foam plugs and ear muffs, you can still sustain permanent hearing loss with a round that blasts as much as this one does. I also read from numerous sources that a compensator increases decibels around the muzzle. Additionally, if I ever have to use it to defend against a charging bear, I probably won't have time to put ear muffs on.

I went to S&W's website and could not find an end cap for either the 460 or the 500.

I am aware that this thread is rather old but I still want to make a reply.

I would still like to get a blank compensator or "blank endcap" for my 500 S&W. My reason differs from the original poster as I'd like to handload some shotshells for the occasional Grouse/Ptarmigan while backpacking. I just got off the phone with S&W, they actually carried them for a very short time but they were a flop as far as sales go so they are no longer available.:mad: Does anybody know where to get one of these without having a custome job done at a machine shop?

I just heard back from S&W too, via email. I found this posting via googling.

They no longer sell the blank end-cap.

Hopefully someone is sitting on a pile of new old-stock 460 end caps who would be interested in selling them...hopefully

A word of caution. My friend tried shooting his 500 S&W without the brake with some of the ammunition I loaded for him.

No problem with the 300 grain loads loaded to 50 AE specs.

Shooting the mid-range 400 grain loads was, according to him, "A very bad idea." That muzzle brake is there for a very good reason.

I intend on shooting this revolver (assuming I can obtain a blank end-cap) in 45-colt.

If I were hunting, I'd be loaded with 460, ported end-cap configuration.
