Colt sells only through distributors, so you'll have to find a store that either has Colts in stock, will order from a distributor; or, look for NIB examples on the auction sites.
before I bought mine I visited and called a number of gun shops in a 50+ mile radius for almost 6 months before I put in an order at Buds. The answer was always the same, we will get some soon, when the distributor gets them. I finally called Colt and they told which distribotors were shipped which models recently and gave me some contacts. I called a few of the distributors who all said tell them which gun shop and they would deliver one when they got one.
Haa! Buds emailed to say my gun was ready! I think the distributors keep the supply low and demand high.
