Cimarron does sell both Uberti and Pietta SAA's and I have handled quite a few of each. If authenticity is important to you then Uberti all the way, for a number of small and large differences I won't go into. If authenticity is not and you just want something for either competition or general shooting, then either is a nice six shooter. Pietta generally feels much smoother out of the box. Lighter springs for sure. Feels like more polish inside as well. Pietta has squared front and rear sights versus tapered front and v-notch rear of the standard Uberti Model P. There are other Model P's like the Evil Roys and stainless guns that do have squared sights. Uberti has the polyurethane finish on the grips. I've seen the Pietta the same way but I think oiled grip is the standard now. The Uberti's could use lighter springs, and for some folks that is all they need. Both brands tend to be timed pretty well out of the box. I think both brands can hold up well for CAS use. Serious competitors would want to get an action job with either, though the Pietta might need less work. I like the Ubertis better for the authentiic issues.
