This Independence Day weekend I got to shoot this recently made Auto-Ordnance THOMPSON 1927 carbine, in .45ACP.
My thoughts:
It's big, long, and HEAVY. 13 lbs.
More than an M1 Garand!
The length of pull of the buttstock is way too long for me, when shooting from any positions other than prone or benchrest.
The stick mags were reliable.
The drum magazine has ALWAYS been unreliable, per the gun's owner. Many jams, failures to feed. But on this particular range trip, we could not get it to lock in place at all. (And yes, we had the magwell adapter).
The sights are good for precise shooting, and the ladder rear sight can be raised high for very long shots. But I'd prefer wider, higher visibility iron sights, optimized for quick snap-shooting at 50 yds.
The trigger is rather heavy and mushy compared to an AR-15 but it is adequate for plinking or close-range combat.
The 18" barrel reduced the noise of shooting 230 gr. FMJ ammo, as compared to how that ammo would sound from a 5" barreled pistol like the M1911.
It's a handsome gun that would look great hanging on your wall, either uncovered or in a velvet-lined glass-front display case or shadowbox.
