Gunsite update:
At around 1000 trouble free rounds I took this to the Gunsite 1911 Commemorative class last week.
Fired roughly 1150 rounds in a week with only basic field stripping, wipe down, oiling done at night.
Zero malfunctions other than 1 FTF when a wad of medical tape on my hand wrapped around the safety during a draw and a couple of poor draws where I failed to get on the grip safety, so no fault of the gun. The Ed Brown fit and dehorning really paid off here. I saw many guys with hands that looked like they had been through a meat grinder from beavertail misalignment, sharp edges on safeties, checkering, etc. I only had one friction blister from where the web of my hand between thumb and finger rubbed up and down flicking the safety on and off. This is where an extended safety might have come in handy. The narrow safety on this Special Forces makes me keep the thumb in very close. I won't be changing the safety for daily use, but if I take another high round count class I would temporarily install a nice wide safety.
After a week of being in a plastic Bladetech holster the finish has a very slight wear right on the front forward edges of the slide, about where you'd expect after hundreds of trips in and out of a plastic holster. The Tucker leather holster was abandoned early on, more on that in the Gunsite review.
I was very glad to have this gun at Gunsite. I watched guys on the firing line fight with their guns all week in this 1911 only class, all kinds of malfunctions from all kinds of manufacturers. Was very happy not to have to put into use any of the failure drill training.
Used only the Chip McCormick 8 round Power Mags, also worked 100%.
Fired about 500 rounds of Blazer, 600 rounds of Remington 230gr FMJ, and 50 rounds of Remington frangibles. All fed fine and shot at about the same POI.
In depth reviews of Gunsite coming, but the Ed Brown continues to just work.
