I have 6 metal clips {3 for HMR and 3 for .22 mag, same clip} and this is what I did. Pull the bottom black plastic peice off the bottom of the clip. The spring will come out with the orange thingy. stretch the string out a bit, an inch or so. then take the orange thingymerdoubous and make sure it has nice crisp sides, I had to lightly sand some plastic burs down. Then clean the inside of the metal clip with some brake cleaner or gun solvent. Put clip back together and load with 6-7 rounds, 8 compressed the spring too much. Everytime you clean your gun, clean these clips. Lots of residue does go down in there and gums up the works. When I first got my 597 the clip jammed constantly, and really p'd me off. I dont remember the last time any of my clips jammed.
