Back in 2013 (and still as far as I know) the Uberti just seems to have less issues vs the Pietta when the Remington is spoken of (the opposite if it’s a Colt), and that’s what I wanted for Christmas. But the deal on a Pitta with a free starter kit ended up coming my way.
My Pietta Sheriff’s model needed a little of this and a little of that done to it. For one, and it’s not to say an Uberti doesn’t also need attention here, the hand and bolt needed the edges smoothed. Pietta definitely has grossly undersized chambers (reamed it to .449” and chamfered), a thick hammer that doesn’t for properly in the safety notches (filed it down to fit), has a loading window only meant for a ball (modified that), had grips that weren’t snug (fixed that along with the nasty stain color) and also are larger than originals (I have small hands so sanded that down too), and has press fit sights and lever latch (newer molds may be dovetailed now), which have occasionally dropped their part, but clearly has no windage (mine shoots a bit left at 15 yds) if it’s press fit.
All that said my NMA has the faster twist and is just about 1/2” off of what my ROA with a 7.5” barrel does. It’s a very good gun and I like to tinker so ultimately I think I did well, though I’m contemplating opening up those chambers a little more. I certainly wouldn’t sell/trade it. But Ubertis seem to need a little less work in a Remington model from what I’ve read. Take that with a grain of salt as some of what I read was old and prior to Pietta’s reworkings. Mostly people feel their fairly close. Maybe you can’t go wrong here.
