I removed the batt. pack from my mag, reinserted the mag, marked it for length, cut it off with dremmel cutting wheel, then smothed and squared the bottom with sanding wheel, then cut a piece of hard rubber sinplicity mower deck wheel, leaving a 5/16 tower to go up inside the mag bottom, smoothed and rounded and tapered the new bottom, cut off 1 in. of spring, put 2 round head screws in the bottom to align the spring, then inserted the new bottom into the mag, and secured with 2 small 1/2 in. long screws. Painted the grips with fusion, and I took her to the range to make sure it worked, and it was flawless, except it is now only 7+1, but it is mostly a night stand home envader protector, and if 8 is not enough, then I'm in trouble.
