Hello. I have a basic question here regarding the S&W 457 and the CS45. I imagine they are pretty much the same firearms, except one is a compact and the other an ultra-compact. Mags are different, the CS45 holds six and 457 hold seven. Are they functionally the same firearm in slightly different capacity or is there a quality issue between them in addition?

I would say that your description of the two comparable pistols is spot on.

No difference in quality that I can discern.
