Nice set, Bill.
I'm late to the thread, but I have the loaded SA 1911 that looks identical to your new toy, with exception of grips. Mine has the slim-grips with SA logo on them. I've had it for 5 years or so and it has performed splendidly for me. It'll shoot one-ragged-hole groups with good ammo and no FTF/FTE issues so far.
Congrats on the new guns, I hope you enjoy them.
