Bought a nice clean standard AO 1911 last year. Has the Thompson bullet logo on the slide. Nice gun, feeds and runs my loads fine. Bought it to go with my Thompson AO 1927a1. Paid 480.00. I use it for Wild Bunch. Didn’t know they made a competition model. I put a Wilson comp on a .45 that I built years ago and found that other than the extra weight out front it didn’t work very well. A comp works much better with a hotter round.

It appears to have a drop-in compensator from Heinie, Wilson or other vendor from back in the '80s or '90s. I had a couple of them, a Heinie 10mm on my Delta Elite, and a Wilson Accu-comp II, and later a Centaur Systems Quadra-Lok on my .45. All of them worked well enough, if you ran the ammo pretty hot. The 10mm would actually recoil DOWNwards with a 135 Nosler and a hatfull of AA#7 under it, the .45s worked well, but not THAT well. Someone did bother to put adjustable sights on it (they look like the ones Pachmayr sold back then). LPA sells something like that now. Add a S&A magwell, and Hogue grips, and you've got someone's journeyman comp gun from the mid '80s down pat. Most all of Kentucky's IPSC shooters in those days were using something along those lines.
None of them were as fancy and well-done as a Nastoff, Garthwaite, or Wilson, but they worked and were good-functioning tools for the IPSC crowd of those days. They were also a lot of fun.

These were made for a few years in the 1990's and went thru a number of changes as to the parts used. Your's looks to be the earliest style with some parts changed. The compensator on all of the versions was a "bushing comp" that replaces the standard barrel bushing and came from one or more of the companies in the Southwest (Accu-Systems?, Accu-Tek?, Chandler?, etc.) that marketed these in the 90's and NOT a Heinie, Wilson, etc. Your's is the first series comp (later comp had 3 straight slots instead of 2 straight and 1 angled). Your gun would have had an extended thumb safety originally and there at least 2 different styles of those used (John Masen?). Your rear sight has been changed to a drop in LPA adj. (original was a fixed GI-ish blade type and these varied also thru the model run). Your's has a S&A maxwell added. Later (last?) guns had a standard GI style short solid trigger and GI style thumb safety and slide release. This model came out near the end before AO was sold to Kahr and it was almost like AO was putting them together with whatever parts they could scrounge thru the model run. These originally came with a original ring style Commander hammers (the hammer on your's has been changed) and all-except for the very last one's-had an extended slide stop release like your's (John Masen?). All had your style beavertail grip safety. I remember that the American Rifleman magazine did a review of this gun when it came out and actually gave it a decent performance review. AO didn't make/sell many of these so they aren't that common but again there's not that much collector value with AO 1911's in general so probably $600 would have been a more reasonable price.

A longish FYI about my AOC Competition Model 1911A1.

I bought it used, as my first and so far only 1911, a little over a year ago. It's a West Hurley gun about 1993 to 1996 vintage. .45 ACP with a 5 inch barrel, 16 pound recoil spring, 22 pound mainspring, 3 straight-port bushing comp, and an AOC wrap-around rubber grip. It weighs 48 ounces with 7 rounds in the mag.
It had an extended slide release which was poorly fitted: it rubbed on the plunger tube. I filed it to clear, and also worked the slide release detent where the plunger engages.
I have 3 magazines, a Wilson Combat, A Chip McCormick, and a Colt. After several hundred rounds, all three had burrs where they protruded into the hole opening (slot) for the stub on the slide release. I marked them and trimmed them to clear the stub. Stub was also hitting the top round in the magazine so I trimmed that to clear.
Additions/upgrades I did include: Nighthawk DTS (Drop-in-Trigger-System - - - lowered measured trigger pull from 8 1/4 pounds to 2 3/4 pounds; Fusion Firearms short smooth trigger with adjustable trigger screw; Hi-Viz Fiber Optic Front Sight; LPA TPU40MK-30 adjustable rear sight; EGW 10000 extra long ejector; EGW 10322 GI extractor (Improved) series 70; EGW 10413 Tungsten 2-piece FLGR; EGW 10369 oversized firing pin stop; Klonimus 50601 Mag release catch kit; extended thumb safety; magazine well funnel; and a Rock River arms PS1317 30-LPI Arched mainspring housing.
Needless to say I guess I was really trying to make a "silk purse" out of a "sow's ear." Now the gun runs very reliably, and is fun to shoot. I can shoot 1 1/2 to 2 inch groups at 15 yards - - - good enough for me. I've run about 2500 rounds through the gun. I wouldn't have had success without all the info provided by members of this Forum and Kunhausens book on 1911's. It was truly a learning experience.

I wouldn't worry too much about the "silk purse out of a pig's ear" corollary as Chip McCormick won his first Steel Challenge Championship with a customized Auto Ordnance (customized by Virgil Tripp but still...) so I think you are in good company. BTW, those John Masen extended slide stops like you have almost always require major surgery to get them to fit in anything as they are so far out of spec it's pathetic and that's assuming they cast the pin inline and not crooked and it will even go into the gun in the first place.
