Pietta question.

[Capt. Montgomery Little]

Bob,  Let us know how this comes out. Inquiring minds want to know.

Gentlemen: FYI,  Uberti and Pietta gripframes are interchangeable if you cannot find the brand you want. I have interchanged Colt gripframe parts to Sauers, Ubertis and Piettas and every kind of mix/match you can think of between these parts. Only modification ever needed was when I put a 3rd Gen. backstrap on my JP Sauer and had to shorten the TG to accomodate shorted Colt backsatrap.
HOWEVER...remember to use the screws that match the mainframe only.  Uberti Thunderer gripframes will fit Piettas. Been there, done that and even converted to cartridge. Check out www.gripmaker.com, Guns and Grips page and view the short barreled Pietta 61 Navy with Colt gripframe and antiqued stag grips. Some NCOWS member should still have these as they were sold at first convention in KC couple of years ago.

That sounds like good news. I've got a GWII that could use a gripframe swap. The triggerguard doesn't quite sit flush with the backstrap.

Got around to trying the grip parts swap between a Pietta cap and ball '51 Navy and a Uberti SAA with birds head grips/frames.   Actually I was just trying to put the Uberti grip frame on the Pietta and made no attempt to try the other way.  The screws stayed with the parent frames as suggested by Capt M earlier.  The good, all holes did line up on both grip frame sections, kinda! 

The bad, the first two screws I tried to put in were the two behind the trigger guard and they did not seem to want to thread in, even though these were the screws original to the frame.  I quickly figured the problem, the angle at which the two parts hole alignments were driled are not on the same plain.  By lifting the trigger frame slightly I could get those two screws in but before they tightened down the front of the trigger guard was angled well up.  It was easy to start a few threads on all three of the trigger guard screws but I am sure drawing them down would cause considerable flexing and probable bending.

The worst, my best option left was to leave the Navy trigger guard frame on and see if the birds head rear grip frame would attach.   First I had to leave the wood off as its channel was slightly to narrow.  The two top screws liined up great but though the base screw  holes can be hovered directly over each other the frame halves are separated to far to be called a fit and the mating surfaces were no where near a match either.

Back to the good, a slight bit of work to get the two holes, mentioned first, bored in alignment and I think the entire assembly would work pretty well but the two grip halves need to stay matched, P to P and U to U.   One last thought, when I pulled the trigger guard off the Pietta, I noticed that pietta has a very slightly raised shelf that the guard rests on and the Uberti SAA clone does not?   I will have to look at my other Pietta clones to see if this is common to them all but I do not have Uberti Navys to check.

I built one using Pietta parts I acquired from Taylor's and company everything dropped in no problem on a 1851/61 frame. Next step was a gated Kirst cartridge converter. Shoots 38 Colt or 38 HBWC.
