I was under the idea I had 2 piettas, but guess they are Uberti, both have the drift front sight. One was given to me, an old one, rougher looking frame, and the grips wont switch between them. The other is a blued steel frame with adjustable sights, guess no longer sold as all I could find was a stainless with the adjustable rear. I had a spare parts kit from a Pietta I had, nothing fits. But oddly the cylinder from a Pietta fits in the old one. But the cyl from the newer Uberti doesn't fit in the old Uberti. Fits but wont lock, the notches in the cyl are different. And a Pietta conversion cylinder works in the old one. The cyl latch in the new one would be narrower and be loose.
Taylors said you had to buy the right cyl, but apparently not? Maybe?
