Years ago i bought a Rossi Puma '92 in .357/38 and my wife got interested in shooting CASS after many years of being on the sideline. So I have this extra rifle but it only holds 9 rnds. If you try to put 10 in there the last rnd will only insert about half way. My local club more ofter than not has stages that require 10 rnds in the rifle so I have been wondering if I can cut the mag spring down a little to get the 10th rnd in the magazine. Has anyone tried this?
