Actually, didnt kimber make the 1st polymer 1911 a while back..... also there is the wilson combat and the charles daly polymer 1911s
Ah... The Kimber BP Ten! I have one and love it, but being double stack, AND government model size, It's not a summer CCW. Even with my baggiest shirt, that long, fat grip prints enough that those who know me know what it is. Shoots beautifully too......

But didn't STI make the first Polymer framed 1911s?
