Help me pick my next 45acp..

[Geeman]

How much for an Uzi or a Thompson

from your list Colt. older GC with rib.

The "other" would be Tanfoglio, My Witness Elite will keep up with my Fred Kart accurized Series 70.
You could almost buy both 45acp and a 10mm for the price of the Colt GC.

I prefer the Gen4 G21 to the 41...voted 41 though.

Some spare Kriss vector mags and your gtg....If 30 rounds of 45acp didn't cut it...you needed a rifle...or close air support.

Metro arms mac bobcut 1911 best gun out for 750-775$ish.

Per Mountain William and Zephyr, I'd go with a Dan Wesson 1911. You can get a Heritage for under $1100 and that is a lot of gun for the money.
