Unique GP100 Here

Cool gun. A fixed sight 38 Special GP100 had got to be up there as one of the most robust handguns ever built. Haha.

Excellent GP there, sir! That revolver is a true tank, in the mild .38 it will surely be capable of shooting a metric ton of rounds before being passed down for generations.

I hated the factory grips that came on my GP .44 Spl. so I put on some OEM compact grips with Chigs grips walnut inserts. They’re much better in the hand and a bit easier on the eyes .



Plus the 360-degree rubber grip gives a decent handhold and absorbs recoil. (Of course, in .38 there won’t be much, if any, recoil at all.)



When you get a chance to shoot it let us know how it does for you.

Stay safe.

Will it actually chamber .357? IIRC, the French police contract cylinders were marked .38, but were through-bored and would accept .357s just fine.

YES actually, it will! I have a couple boxes of magnums here and they drop in and the cylinder close perfectly fine:

Looking through the chambers, they are bored straight through. I can’t imagine there would be much accuracy considering the cylinder doesn’t have throats.

Defintely going to ring Ruger tomorrow morning.

If you're gonna try it, please call Ruger first. Last thing we want is to hear the tale of how you blew your hand off.

A few years ago I gave my sister in law a ride to the hospital for lab work. While I was waiting for her, I saw 2 State Prison guards escorting a prisoner from the hospital to the prison van, parked not far from me. Looked to my like the guards were carrying GP 100's.
I would think a fixed sight, 38 special GP100 would be the perfect prison guard gun

Seems strange Ruger would bore out a cylinder of 38spl revolver making it capable of chambering 357 cases if it's unsafe to shoot 357. If it's not safe for 357 i would bet they'd be more than happy to correct it for liability reasons. Definitely worth a call to Ruger. While you're at it might be worth while to ask if the gun was a special contract over run. Good luck and fine gun in any case.

I think that's why it's labelled .38 SPCL instead of .357 mag. But you absolutely bring up good points. Maybe there's some writing in the paperwork it came with?

JCooperfan1911 said:

Exactly, I’m going to call them for sure. Even if it’s safe for .357s, it literally is just bore straight through and has no chamber throats. That isn’t right at all.

Pretty sure thats how they came. Ill betcha the part #s for the .38 and .357 cylinders are exactly the same. The .38spl stamping was just to appease the image-sensitive agencies that bought them.

The other possibility is that someone had it bored after the fact. That was a common modification on both Ruger and S&Ws back in the day.

It is a cool revolver. I would love to come across one. I think it might the perfect woods gun if one doesn’t have to worry about those furry things which I will not mention that spark so much colorful and entertaining debate.

I really like that revolver. Nice score!

That's very neat, but I don't grok:

. . . “GPNYs” and like my gun they were ,38 only, fixed sight, full lug,

Why would anyone ask for a full lug .38Spl, to be carried?

Huh? You don't think .38Spl is enough for beaver? Heretic!

While I have Lett compact grips I use and like a lot, I’ve also been liking this Hogue non-finger groove version…
It seems just slightly smaller in circumference than the grooved version, and fits my hand better.

My idea of a 38/44 or Heavy Duty Smith.

Definitely better grip for that GP

Using a GP for a carry gun is like having a Boat Anchor in your paints.

sweet gp100.
I'd bet the cylinder is the Same as the 357, I don't know for sure though. I'd check with ruger of course , you could always make 38 special loads in 357 brass for a little bit more case capacity - if that's desirable to you.
Do the way, cool revolver that should survive just about anything.

It's the same GP100; talked to Ruger tech years ago the cylinder is just drilled for 38 and not 357, it was a contract requirement.
