I just used my new SIG 1911 in a tactical carbine/pistol course over the weekend.
It's one of with the all black finish, although all of the guns are stainless, regardless of finish.
The trigger got better with a couple of hundred rounds downrange, plus lots of dry firing, but still is slightler heavier than I like....(haven't put a scale on it yet, but will when I get home.)
Accurate enough, no functioning issues with factory Federal 230Gr. ball ammo.
Very tight slide to frame fit....bushing wrench required for disassembly.
Novak sights easy to pick up and score centre of mass hits out to 50 metres.
The finish was a little worn in the areas where my holster made contact, but overall not too bad....
Be warned that these '1911's won't fit in standard 1911 holsters...I ended up having to use one of the 'universal' adjustable thigh rig holsters..no biggee, but still a bit of a PITA.
Many eschew the inclusion, or need, of the external extractor, but I personally see that as the weakness of traditional 1911 models....me likee!
Overall, for $1050 + tax, I am pretty happy with my purchase, and would recommend these to people sitting on the fence.
