Colt has announce that for 2013 they will be offering a civilian version of the M45 to the consumer market. It will be hand fitted in the custom shop and supplied with a test targete showing a minimum of a 1" grouping (distance for that grouping unknown). The will be packaged in a special case and come with two magazines that have been pre-tested with the gun to ensure function.
While it certainly won't be cheap, it sounds like a nice package. Clicky
to see for yourself.
