It's very heavy, feels like 20+ lb. You immediately notice all of this slide weight when first picking up the pistol. The recoil spring, guide rod, spring plug, firing pin, firing pin stop, hammer, sear, disconnector, magazine catch spring which recoil springs. I have not a clue what # weight of recoil spring it is, but it is very light and according to this post.9lbs is the norm.
