Considering that the original 646PC guns sold for over $800, these new ones are a bargain. My understanding is that these new guns are in the mid five range, which is not bad for a somewhat unique weapon.
The older Performance Center variant was very temperamental. For revolvers that are suppose to be extremely reliable, this gun failed the test. Ammunition selection for the 646 was critical. Gun digests most brands of commercial ammunition, but handloads were a totally different ballgame. The titanium cylinder has a problem absorbing pressure spikes due to the extremely thin walls and requires medium to slow burning powders in order to function properly. Bullets also require a firm crimp.
Been playing with this gun for some time now and was very frustrated at first. I was bent on either figuring the problems and mastering the gun or blowing the darn thing up. My 646 spent lots of time with the cylinder removed on my work bench and pounding out cases with a dowel. A true test that these guns are stronger than what most think. Over time I mastered the gun and today it is one of my favorite shooters.
Anyone looking for a turn key, I'd pass.
Looking for something unique that requires a little bit of a learning curve and the end result will produce a new level of performance, then don't pass this one up.
