Here's a reccomendation you probably dont want to hear. Why are 1911s so over priced?
$750.00 gets you a low capacity entry level gun. Oh boy
How about reevaluating your purchase. You want a Full size steel Gun that shoots 45 acp Try 1. Smith 4566 tsw 2. 4566 3. 4506 4. sig P-220 5. CZ-97 All these guns can be had for less than $750.00 new or near new. And, they are top of the line guns, not entry level.
Good Luck
