I'm a big 1911 fan ( been shooting them well over 40 yrs )....and about 15 yrs ago, I started to invest in some 1911's in 9mm.....
1. a Les Baer Monolith ..5" gun... ( series 70)
2. a Kimber Tactical Pro II model ..4"..alloy frame...( series 80)
3. a Wilson Combat - Protector model, 5", all stainless...( one of the finest guns in my safe ) ....and equally as good as my Wilson Combat CQB model in .45 acp....( both series 70 guns )
The two Wilson's are 2 of my top 5 guns...( including the 9mm ) ....and I shoot that gun a lot - I purchased it new in mid 2006 / and to date I have fired over 85,000 rds thru it ....

While I will always want a 1911 in .45 acp.....I'd be hard pressed not to have at least one in 9mm as well.

Like someone else said Colt is making the gold cup in a series 70 again.
Colt is making other models in 9mm as well now...about $ 800 or so ...and based on what I've seen they aren't bad guns...but at that price point they've left off some things ( like no checkering on the front strap).
