The drop free magazine brake isn't so drop free! You need to do some sheet metal work to get it to work. First tighten up the pin holes on the top and bottom. You can tighten the top by putting a punch through it and squeezing it in a vise forming a perfect hole for the roll pin. The bottom will need to be bent up with a pair of needle nose. When you install it it should be stretched between the 2 pins. Final operation is to mark it where the grip screw holes are in the frame. Put the drop free magazine spring in the vise and bend it forward so it will form a slight "V" and have pressure against the frame. Polish with some 220 grit and crocus cloth and now it is drop free!
