GP100-44

I received a reply from Ruger customer service today...addressing my concerns of the GP100-44 special being able to accept 44mags. Ruger CS stated that the GP44 is only chambered in 44 special and will NOT accept 44mag rounds. Apparently CS is not on top of the issue. And the front sight not fitting...it falls into acceptable specs...according to Ruger CS. Sounds like ruger is starting the spiral down the waste stool...

As far as I know if a cylinder is chambered for a nonmag round (shorter) round. The longer mag rounds will not go in due to the length

During a 30-minute phone call with a Ruger product manager on Sunday, among other things I brought up that .44 Mag issue.
He acknowledged it.

He was not surprised & did not deny it.
Specs between chambers (he also said that the same situation has existed with Smiths) and SOME .44 Mag factory loads WILL allow a .44 Mag load to seat fully & function in the new Ruger GP44.

As I've mentioned, one Black Hills load I have here will.

Whether Ruger's Service people are aware of that or not is unknown, but it's certainly known elsewhere inside the company.

Re the front sight, again the CS guy or gal was not up on current events.
It was acknowledged during my phone call Sunday & I was told it's being corrected on new production guns.

I was also given the usual "Send it back for corrections" suggestion if the sight, or anything else isn't right.

CS needs to be updated, apparently.

Other issues are being addressed, but the ability to accept SOME .44 Mags is probably not going to be one of those.

Basically- just don't do it.

loose chamber throats will allow this. I had a smith 25-5 in the late 1970s that would easily chamber 454 and the cylinder would close no problem. 25-5s were notorious at he time for very large chamber throats

i posted the following on another forum earlier today and thought i would cut and paste it here for reference as the post states i think we all know this by now just thought i would add my example.

"been watching all this and finally got around to checking my gp44 example and thought i would post the info for reference sake
gp.44, 4 throats at .434 and 1 at .433 using pin gages ( M2 minus with claimed accuracy of +.0000", -.0002" and checking with caliper seem correct)
for comparison i have two flat top bisleys and both wheels are at .431 for all twelve holes

i think all this has been found out already but thought i would add my example for comparison

by the way i have not yet been able to fire the gp but hope to soon"

The load I have here that seats fully in my sample gun also does so in the tightest chamber throat, measured at .427.

I'm not sure it's a loose throat issue.

I have read a few posts on the GP100. 44 Special, being able to chamber .44 Magnum loads. One forum member was using his .44 Magnum reloads as a example. Due to his heavy roll crimps was the factor why his gun would accept.44 Magnum loading. He then as was suggested to go to a LGS and try a new factory .44 Magnum loading which didn't fit into his gun! So yes there are some differences in certain Ruger GP100. .44 Special's. Myself I looked very carefully for over 2 years before I bought my Ruger GP100 WCII .357 Magnum. I am very satisfied with my Ruger GP100, but I haven't had any problems because I checked over my revolver carefully.

Just hauled out my old 25-5 in .45 Colt.
Mine has the oversized throats of the early 1980s (I got it used in '82).

Only tried two loads, both Buffalo Bore .454s.
One won't allow the cylinder to close, the 360-grainer will.

I COULD load up & fire that .454 stuff in the gun.
At least once, anyway.
But I won't.

I dunno if that's a function of the oversized throats, or the length of the chamber cuts.

The Ruger .44 GP's ability to fully chamber one or more .44 Mag loads is not a phenomenon unique to either that gun or that brand.
But- it does exist.
If you look hard enough, you CAN find a factory .44 Mag load that will fit.

Just don't do it!

This raised my curiosity, so I just tried some 44 Mags in my S&W Model 24-3 44 Special. One of my mag handloads fit easily and one did not. The only factory ammo on hand is 300 gr WFN from Grizzly Cartridge. It dropped right into the special cylinder. So there ya go!

If I am reading the posts correctly,this is what you should do.Before you purchase,try a 44 magnum in all 5 cylinders and if they fit ask for another revolver until you get one that will not accept 44 magnum.I also realize that currently one is lucky to find even one,but that should change with time.Am I correct in my thinking?

To put this in perspective:

The concerns about the ability of SOME .44 Special guns (Smiths, Rugers, whichever) to fully seat & chamber SOME .44 Magnum rounds (factory OR handloads), lie in the fact that common sense SHOULD handle the situation, but we all know that Rex will try it anyway.

Note all the complaints across multiple Internet forums in initial discussions of the new Ruger GP .44 Special- "But, it AIN'T a MAGNUM!!!!!"

The issue is not a safety deficit in the gun, and the solution is not to take a (note "a") .44 Mag cartridge along to the gunshop & try it through several guns till you find one that won't fully seat it.

The issue is that the manufacturing processes inherent to both guns and ammunition are simply not precise enough in tolerances to make sure that NO .44 Special revolver will EVER chamber ANY .44 Magnum round.

The solution is to simply not try to shoot a .44 Mag load in a .44 Special gun.

As mentioned, most .44 Mag factory loads will NOT chamber fully in a Smith or a Ruger .44 Special, and you may have to look through several different brands & loads to find one that does.

I had to go through several .44 Mag boxes on the shelves here to find that one single Black Hills load that would fully seat with all five chambers loaded up out of that box.

Taking one .44 Mag cartridge along & trying it in however many different Ruger GPs a dealer may have in stock would tell you only that THAT cartridge would or would not fit in THOSE guns.

Not a reliable methodology.

In the meantime, these discussions are a cautionary advisory, and not a condemnation of Ruger or S&W.

The thinking man will avoid trying Mag loads in Special guns, recognizing that it's a "Just because I can, doesn't mean I should" situation, while Rex will carefully reason out that "Hey, they's ALL .44s. If it fits, it shoots, and I want more POWER!!!!!!!"


To reiterate for anybody still unclear- the GP .44 Special IS NOT DESIGNED TO HANDLE .44 MAGNUM PRESSURES.

Just don't try.
