No, not with that gun.
I do have a 45ACP RIA M1911 A1 CS-Tactical. (
ROCK Standard CS - 45 ACP | Armscor International, Inc)
It's 7 + 1 with the Armscor branded ACT-Mag. It does not have fiber optic. It has drift adjustable front and rear with white dots. The rear is Novak style. It's a parkerized all steel 3.5" Officers Model size.
Never having owned an Armscor gun before I was a bit skeptical. I loaded a large pile (500+) of standard to slightly hot (I don't have the recipe handy) loads using Phelps cast SWC plus I dug out 150+ of assorted factory rounds and took it to the range a few times. From brand new through all of those rounds not one malfunction of any kind. Not one. Accuracy was "good combat". I'm very impressed with the gun, especially at it's street price which I don't recall at the moment but it was very reasonable. It's currently $475 at Tombstone Tactical but I've never bought anything there.
I'm pretty sure the 9mm you're looking at will be good. However, if only giving up one round to go 45 ACP over the 9mm, I'd go 45. But whatever.
