Neither is going to reduce weight if that’s the real issue. She could try an alloy j-frame, but recoil of alloy j frames is unacceptable for many. I have one and have to use a rather large hogue grip to make it shootable. By contrast, the PPS has amazingly little recoil. I had been concerned that it would be difficult to shoot with the short magazine (2 finger grip) but it’s a non issue. Issues for your friend will be whether she can jack the slide. There are some new models from S&W and Springfield (EZ models) that have reduced weight recoil springs for shooters with limited hand strength but neither is a small gun. Designers need a heavy slide if the spring is weaker. Between the CCP and PPS there no contest, PPS is a much better weapon with a good trigger, easy take down, and it feeds anything with no hiccup. CCP has a safety, which is small and could be difficult to operate in a moment of necessity, out of the question for me. CCP is larger, and the trigger is long and indistinct. Try Federal micro ammo, about the same power as +p 38, tests well, and low flash, low recoil.
