if that's with a ducktail tang, that's one thing.If it's measured with the hammer down and a Detonics grip safety, that's something else again.
There's 3/4" of difference, ya know. A hammer down, SA auto aint very fast into action. If somebody made a 6.5" long, ducktail 1911, 20 oz, with polymer frame,I'd sure buy one, in 9x23, and get spare barrel and mags for 9x19 ammo for it.
