I have a pair of CZ82s that still have their original recoil springs. A growing problem is that chambering a round with my arthritic fingers is increasingly difficult. The resistance in pulling back the slide has become darned near impossible. Every CZ video I see looks like a child could easily rack the slide. This would appear to be simply an overly strong recoil spring, right? If so, what size spring should I be needing. Your welcomed thoughts?
