The only was to verify the claim by the RIA 10mm GS is to put it through the test. I will let y'all know what I find out when the springs come in. The 16# will be here Monday or Tuesday, I'll order a 20 and 21lb Monday.
Yeah, that guy has no clue. I think Dan Wesson runs ~20lbs in theirs too. I KNOW Wilson recommends 20+Lbs because I talked to them about a 10mm conversion for my .40 CQB earlier this year. Read up on some of the other 1911 forums/10mm forums and you'll see what everyone runs. Shock buffs are junk. If it's sprung right, you should have any battering, even with hot loads.
