Works goodGot this for my Gen 3 G20 since the old recoil spring was getting worn after a couple thousand rounds of 10mm. Its a true OEM part so it drops right in no fitting or anything, took me about 2 minutes to swap out. You can see its marked 5600 on the end of the guide rod which is how you know its the real deal. Shoots way smoother now and the slide cycles like it should.
