Well, I went back today & bought a 30S (he still had a couple). I will shoot it tomorrow along with my G30SF to see if the recoil is acceptable... I feel sure it will be. I did notice that slide peening has already begun, with just the factory test rounds! At least there are noticeable marks on the slide & locking block. Even my G30SF with a couple hundred rounds on it does not look that way; the lighter slide is obviously moving much faster than the regular G30 slides. It fits a couple of my G30 holsters, but is a little loose in the Askins Avenger type (actually an older Dillon for G21's that I had shortened for a previous G30). I can tighten that if necessary. The trigger bar is a -2 instead of -1. What's that all about? Is that unique to the G30S?
