This weapon features the unprotected, early style Lyman L sight, has the later buttstock with a reinforcing crossbolt, and pin-style fire control levers.

You should be able to simply push the slide stop back in.Such an inspector stamp is the easiest way to quickly identify an Auto-Ordnance Bridgeport manufactured M1M1A1, since Savage M1s were not marked with S prefixes like the earlier M1928A1 models, and are extremely similar to the M1s manufactured by Auto-Ordnance in Bridgeport, CT. Doing that typically makes a scratch shaped like an arc on the frame. When you re-assemble, the slide stop should not need to be rotated into position. You don't really need to detail stripĬlean.everything Lube according to manual referenced belowĪssembly is the reverse, but be careful of the barrel link position You have just field stripped your pistol. Remove guide rod (and spring if it did not already come out) The pivot for this lever goes through the barrel link. Push the slide stop out from the right side of the pistol and remove. Be careful- don't shoot that spring into your eyeĬock the hammer and move slide back until the disassembly detent (as opposed to slide stop detent) is over the small upwards facing 'tang' on the slide release lever Press in the plunger under the barrel, rotate the bushing to the left side of the pistol, remove the plug (and possibly the spring). The breakdown and cleaning is the same as for any 'GI' type 1911. I don't mean to say 'my old POS gun is better', BTW- my 1918 Colt is a heck of a pistol and is as accurate as my 1978 Series 70, which is a pretty accurate pistol My A-O is not the most accurate or reliable 1911 type I own- my 93 year old Colt is more reliable and accurate. Use some red loc-tite on the inside, were it is staked Overall I think the A-Os may be a little ammo-picky- use hardballįront sights are known to come a little loose on A-Os. My original WWI Colt 7-round mag makes my A-O work pretty well.

After a polish on the sides of the trigger bar, it was a drop-inĪ-O mags may, well, suck. I have also installed a WWII USGI trigger in my A-O. I have taken the barrel and slide from my 1918 made Colt Model of 1911 and installed them on my A-O 1911A1. It means the chances of a better pistol go up if it is a Worcester made example That doesn't mean a West Hurley gun is bad. The West Hurley guns have given the A-O 1911A1 a bad rep, with some poorly made examples getting their way out the door. Might want to edit out the last few digits of your s/nĪ-Os were made in West Huey NY and Worcester MA.
