.460 Rowland conversion??

Big Shrek · Jan 30, 2016

Just found out about this nifty round...
folks have stuck it in 1911's, Glock 21's, and Springy XD's...

According to what I've seen so far, its simple...
new recoil spring, new or rechambered barrel,
and the .460 barrel allows use of .45acp,
one just has to clean the barrel before using .460 again...

Given the ballistics and the vids of ball-gel/water jug testing,
it's basically .45acp on steroids

It uses a slightly longer case so one doesn't mix up between .45acp

After some contemplation, finding one of the smaller 45xx's to use for conversion

But it needs to be a steel frame...

What do y'all think??

Haha, a Chief's Special. That'd be a handful of pure seething hate.

I played with .460 Rowland for a little while in a Rem R1 1911 with a Clark compensated barrel. It was controllable but definitely energetic.

Beating up an already well-used 4506, I could see that. But a CS-45? Well, maybe it would survive a bit longer than your hands would.

Definitely report back

If you were talking about conversion to 45 Super (28K psi) that would be more realistic, but not 460 Rowland. Way too much pressure (& slide speed) at 40K CUP.

A conversion to 45 Super would be fairly simple but that short slide (& spring) would still be the issue.

Most (all?) of the 1911 conversions I see have a special ported barrel to slow the slide down. I've never shot one but a local dealer converts them & tests them at the local indoor range & they're pretty impressive! The brass fly wildly!

While the case is longer the max COAL" is the same as the 45ACP at 1.275" so you're just packing more powder in the same space, given the same bullet in each.

The reason for the CS45, is that putting a standard length 45xx series
barrel on it would allow for threading...for a dual-port compensator

Probably one of the smaller 45xx series would work slightly better...
Which one would be the best SMALL 45xx pistol to do it with??

And yeah, it'd be a handful of mean, nasty KAPOW!!
Saw a Glock 30 conversion to .460R, and it was Evil, but Nice...
kind of like the redheaded female Marine I married...

It would probably be less expensive/far easier to use a G30,
but not near as much fun as a S&W 45xx would be

Please don't do it.

Big Shrek,

The other posters have raised valid issues.

I have a 4506-1 (aka the tank) with the 45 Super Ace conversion. Using VV3N38 it will launch a 230 bullet at almost 1300 FPS. Recoil is ...... amusing.

The OAL of the Rowland is the same as the Super, but the pressure level is 38,000 CUP for the Rowland vs. 28,000 CUP for the Super.

The CS45 was NOT designed for these pressure levels.

S/F,

Ah, I don't think I'd do it

Boy I don't think I'd do it for a couple of reasons, none of which have to do with the "probably not strong enough issue" which is the real biggy.

I love conversions but isn't the CS45 an alloy frame? That would be my first concern. My CS40 has an alloy frame and I was going to do a 10MM on it but haven't found the right recoil spring and with some of the hotter .40 S & W ammo out there, I may not do it at all.

The second issue would be the recoil spring. I don't even want to think about what weight that puppy would be! With my 4013 10mm conversion the 23 lb. spring is a handful, and even with the buffer I'm still concerned with the alloy frame cracking; even though BM1 says not a problem. My concession to the 4013 alloy frame is to put the slide on a 4516, it fits perfectly. Of course now that nice light concealed carry unit is a whole lot heavier.

Wonder if the CS45 slide would fit on a 4516, maybe that is the way to go but then again it becomes bigger and heavier. A conundrum to be sure! Good luck! You just can't beat the laws of physics!

This^^^^!
Well actually, this would be the reason I would not do it on my alloy frame but I wouldn't mind doing to someone else's pistol, although it seems almost cruel.

.460 Rowland conversion??

Should one convert a CS45 to .460 Rowland??

Yes

No

Are you crazy?

John Wayne would do it!
