Yes. Fits perfectly.Exellent...Galco .357 GP100 rig there?
will the GP100 cylinder's length handle the length of a spec'ed .44mag chamber?
.357 Mag max OAL is 1.590". .44 Mag max OAL is only .02" longer, at 1.610". I can't imagine that tiny amount would be enough to cause any issues due only to cartridge length.
But don't hold your breath waiting for it to happen. Ruger's reputation is making revolvers that hold up for two lifetimes. .44 Mag out of a GP100, safely, might be possible, but I expect it'd be pushing things to the point that the guns wouldn't hold up nearly as well. I just don't see them doing it.
I would like to agree with you but since they produced the new light frame Vaquero I don't know if they are going to stick with building guns as strong as they used to. Companies change over time and I'm not sure of Ruger any more.
Loads in the 20,000 psi range
will prove useful for U.S. Fire
Arms revolvers that are 100 percent
American made (after the
year 2000), Colt New Service,
Ruger New Vaquero and Smith &
Wesson post-World War II N Frames,
including Models 25 and
625 Mountain Guns. Loads in
the 32,000 CUP range should be
limited to Ruger Blackhawk, Vaquero,
Colt Anaconda or other
modern revolvers designed to
stand up to this pressure level.
The Freedom Arms Model 83,
Ruger Redhawk and Super Redhawk
are capable of handling
much greater pressure than will
be presented here but are safe
with all loads listed.
