I've looked again - noticed the peening - a friend of mine has a couple of stainless smiths they all look much worse then yours and I always wondered why - untill we where shooting one day, we were no more then 8' apart and I was shooting a ported 445 supermag , I had plugs and muffs on and while I was looking at primers of the rounds I just shot I could hear this sniking sound - it was my buddy thumb cocking his gun - now I only let him shoot my rugers - I would still oil it up and forget about it - by the way those grips look great - hope this helps
