DVC - I hate to seem ignorant but where do you get said skateboard tape?? Your work sure looks good. I recently bought a " gently used " R9s and had a few problems after about 30 rds but I was not letting it cool more than the time to reload and it is an older model with old springs( both recoil and mag) and about 35 original rds through it. I think a combination of dirty and hot possibly caused all my failures, which was only two if I don't consider the large hollowpoints I tried(not GDHP)!! I am going to use the two mags and cool method next time AND I'm going to try some Silvertips but I am torn on which weight. The web of both hands sure got red though.....
