I have for a while now liked the idea of the S&W 610 revolver in 10mm / 40 S&W but they are a rare revolver.
I was looking on the internet and I spotted that a guy in the US is converting Ruger GP100's to 10mm / 40 S&W (http:// www.clementscustomguns.com/rugerdarevolvers.html)
Has anyone heard of someone up here in Canada that can do the same or would be capable of doing this?
I think that one of the Ruger GP100 revolvers in 10mm / 40 S&W with the 4.2 inch barrel would be a nice gun.
 
Still Alive had a 5 inch 610 for awhile and sold it on the EE last year. It was nice to shoot. That said, the conversion you cite is pretty expensive, and I've not seen anyone doing similar up here.
 
Thanks for the reply. What you have stated is what I was thinking but thought I would just put it out there and maybe get lucky.
Oh well maybe I will get lucky and one day come across one of the 610's.
 
I thought I saw that charter arms made a revolver in 40 S&W but I may be mistaken. It wouldn't be the first time I didn't know what I was talking about.

The only downside to the 610 is having to download your ammo somewhat compared to most autos. The cylinder is a tad thin and makes extraction of hotter loads a bit sticky. Just my experience, since we can only shoot paper anyway it's not a huge deal.
 
I think he means that you can't load the 10mm stuff to full power without it deforming the brass enough to make extraction difficult.

That still seems a bit odd. It suggests that the chambers are not correctly shaped or perhaps has too coarse a surface finish if the brass is locking into the chambers. I've certainly never had any issue with my .357Mag brass which is running around the same peak pressure. Or my .44Mag brass for that matter.
 
I'm thinking B is referring to top level 10mm loads that only a few here in Canada understand.

Happens in my Ruger Super Redhawk chambered in 454 Casull as well.

Due to the cylinder metal stretching when top pressure loads are fired the cylinder/brass expands then the cylinder metals contract but the brass doesn't.

357's and 44's are normally loaded to lower pressures.
 
Ah, I hadn't thought of that possibility. I'm not sure I'd feel warm and fuzzy if the chamber walls are stretching that much. But I don't read about these things blowing up so I guess they've nailed it.
 
I have fired some pretty hot loads out of mine and never had a problem with ejection.

I am on the Smith & Wesson forum in the USA all the time and I have never heard of anything like this happening but of course that doesn't mean it hasn't.

Why convert a revolver? IIRC 10mm was an attempt to close the gap between weak pistol rounds and powerful revolver rounds. Because pistol rounds are more limited in size because they need to fit in the grip.

I looooove the idea of 10mm pistols. for a revolver ill stick with .357 or .44 mags.
