1st, it is brand new Chiappa for CD, 5" full size. With mag loaded with 8 rds and inserted into mag well, chamber empty, hammer down (not cocked), I grab the slide to pull back to load a round. The slide takes super human strength to pull back, like Superman strength. Believe it has something to do with the hammer because....with empty mag installed, chamber empty, safety off, HAMMER FULLY COCKED, I grab slide and it pulls rearward effortlessly!!!!! Explain this one. Called factory n they want me to return it. Want some input before I do. Semper Paratus
