I'd like to suggest that you steer away from the Sig Pro 2022. I bought one about 6 months ago, sold it around 2 months ago. I shot it at the range, and for around the first couple mags, it jammed every other shot. after that, it jammed once per every mag (or couple of them). I was using Remington UMC 9mm. It could have been a lemon, but I wouldn't take my chances.
Also, I feel that the grip is poorly designed, for a Sig. If you take a look at a picture of one, the magazine bottom plates for this gun comprise about 1/4 of your forward grip, with the other 3/4 being the grip of the actual gun. Very poor design, IMHO, for a couple reasons:
1 - mag moved a lot inside the gun (back of hand was hitting mag plate from the side a lot)
2 - had to remove my pinky from the grip whenever I wanted to reload
3 - it just felt bad, it's nice to have your whole hand on the gun, not a finger of your hand resting on the magazine baseplate. I'm not saying this applies for pocket pistols or subcompacts and such, but I wouldn't expect that on a gun which is as large as the 2022.
My dad also talked to a FFL when I was trying to sell mine, and the guy called his distributor, who told him that the market was flooded with 2022's because they haven't sold for whatever reason, and therefore they are cheaper in price relative to other sigs. The distributor was really trying to dump it's 2022's. That's what I know.
I can't comment on the PCR, wish I could. Happy shopping and good luck!
