It's not a collector but is in good shape and shoots well. It's a Covina model. Which I've always heard was the better of amt.
I have heard long ago that the Covina 1911's were made from softer stainless steel than the others marked Arcadia and Irwindale (IAI).
Never owned an AMT Longslide (shot one many times that belonged to a friend in the mid-90's and don't know if it was a Covina or not: it shot and ran well) but I have owned a Covina Hardballer (ser B260xx) since circa 1992. Bought it outside a gun show in Alaska from a guy who was a security officer of some type. Paid about $150 for it with Pachmayr Sig grips and 2 factory mags. After the gun and money changed hands, he told me it was a "dangerous" gun.
He was correct about that pistol. When cocked and locked, a press of the trigger dropped the thumb safety AND the hammer! Completely disassembled the gun and, after much puzzlement, found that the sear pin was bent.
I am thinking very soft steel here.
Replaced the sear pin, hammer pin, extended thumb safety, hammer strut, extractor, and firing pin with blued carbon steel components. Also throated the barrel (thanks to Jerry Kuhnhausen) to make it run with even the old Speer 200 gr. JHP Flying Ashtray reloads.
It is and has been my truck gun and HD pistol since then and runs well, but after 20+ years of use it's not very pretty any more.
Yeah, I know it's not the factory gun it once was, just better.
