Nothing wrong with the gun as is, but if you were looking to get some upgrades, you might consider the following. There was a thread in here some months back, but it has been lost to the archives. SGB changed out most all of the MIM parts on my girlfriends and my Warrior. Doing this will replace potentially weaker MIM parts with inherantly stronger machined steel parts. You cant really view the old thread unless you are a member here, but I was able to extract the parts list. These are the part numbers from Brownells:
Part # 087-000-009 or 087-000-010 Ed Brown HardCore Hammer. We got the blued one.
Part # 087-815-001 or 087-815-101 Ed Brown HardCore Slide Stop. We got the blue one.
Part # 087-812-000 Ed Brown Match Sear
Part # 087-809-100 or 087-809-101 Ed Brown HardCore Firing Pin Stop We got the blue one.
Part # 087-811-000 Ed Brown Match Disconnector
Part # 087-046-832 Ed Brown Solid Barrel Bushing There's several on the page, we got the part number listed.
SGB also suggested the Kings ambi safety. Brownells tells me they discontinued that item. We'll probably get one elsewhere.
