.45 GAP in .45 ACP Revolvers?

[CountryGent]

According to what I am finding on these here Intratubes is that is safe to fire .45 GAP in .45 ACP revolvers, chambered in the aforementioned, and fed by moon-clips. Any reason that would not be so? (And this isn't quite as random as it might appear. There is at least a couple boxes of said Glock cartridges that have sat forlorn on the shelf at a local hardware store for years. No one, evidently, had any use for them. But if I can burn them up in a S&W 25, is good for both the proprietor and for my wheelgun antics. )

For a second there....I thought that this thread was from the NWFA "Experiment King"...

A quick look at the 'net...says you can..just take the pressure difference into account.

Speaking only for myself...
I wouldn't do this if I had a super nice Smith and Wesson Model 25-2 ...
Would hate to read about that revolver gettin' wrecked..or otherwise damaged.

Oh, if I have any doubt, and at the present I do, I will not do so. Not worth it and .45 ACP is available everywhere. Mental math, and Internetz, tells me is no problem, but those both have been proven wrong before. To get in practice and as not go up hill to home range, I've made little revolver range outside home office between said and hillside garden. It would be unseemly to cover said, or the noggin where (giggle) mental math happens, in revolver shrapnel. And particularly so, to my friend's point, if is 25—2 Target model.

Yes.

GAP is just a shortened ACP.

I have a case of that crap sitting around here somewhere. For some reason it never occurred to me to get a 625 to shoot it all up. Damn you!!

I would also like to own a nice Smith in .45 ACP, now....

It wouldn't concern me in the least to feed a 45ACP revolver 45GAP if it used moon clips.

A brief search suggests the GAP is at pressures roughly equal to ACP+P loads and that pressure is going to be on a smaller surface area so... It might matter? But probably not.

I doubt pressure is an issue at all. N-Frames are built around the .44 Mag, which IIRC is around 36,000PSI. The ACP is 21k-ish.

I have shot .45 Super in my 325TR with no issues and it has more pressure than .45 GAP or .45 ACP +P

YMMV

Well that settles it, then. Thanks for the info

A little more info, further confirming it's use is the IDPA allows .45GAP to be used in .45ACP or .45 Colt revolvers just the same as they'd allow .38 special in .357s. can't imagine they'd give it the ok if it weren't perfectly safe and it may even give an advantage in loading/unloading speed since they're shorter...

Shorter and squatter is always better when it comes to rapid revolver reloads.

I ended up not bothering with this. Just easier to buy .45 ACP bool-its in bulk. (Though the small stack of .45 GAP boxes still sit collecting dust on hardware store shelf. )
