I got my GP-100 in .327 Federal lightly used -- and with some customization that is typically welcome on any gun, mostly any revolver, but I still find quite curious on this one... it had been Mag-na-Ported.
I'm sure it does what Mag-na-Porting always does, but .327 Federal recoil isn't what I would call excessive in a large-frame handgun like the GP-100.
It's a riot, I have a heap of fun with it. I do take advantage of versatility -- but I do it all from .327 Federal brass. I load 71gr FMJ pills (.32 Auto slugs), I load the 85 and 100 grain XTP's and I do
not go easy with them. And lately I've been experimenting with a 115gr cast lead Penn bullet, and those run very well for me with minimal to zero leading. (though a bit piles up above those ports!)
I use my .327 Federal for the same thing I use just about all my other handguns for: screwing around and having fun on the range. Punching paper and dropping steel targets.
The Hogue grip feels really nice in my hand, but I can't stand the way that grip looks. I'm trying to figure out which direction to go with it.
If I had to come up with a complaint, well -- I've got two. The trigger return spring is much heavier than it needs to be. I don't mind a heavy hammer spring, it's busting small rifle primers after all, but the trigger return spring needs swapped out. One day I'll get the gumption.
The other complaint is what I had to spend to get it. Fact is, these don't show up used in the circles I travel. I wanted to pay used money for one, not new money, so I don't feel like I stole this one at $550. I
like to feel like I got a steal on a gun buy. I suppose the Mag-na-Port job has some value, though I still don't think it's necessary on a beefy .327 Federal.
Oh yeah, I like it a lot. I'd like it even more at $450
, but I've done -really- well on plenty of other gun buys, so I'm okay with this one.
