I bumped the Coonan post of your review on the semiauto forum. I dont think I have ever seen a 10mm as hot as that 357 magnum.
Run Underwoods's 135gr Nosler load out a 6" barrel. I know of a couple guys on the old 10mm forum that topped 1800fps with 6" Glock barrels and 135gr Noslers using Hodgdon Longshot.
Once again top to bottom they are very very close
