I'll wait as long as the gunsmith says it'll take. For the kind of skilled hand work these take, and the number of good smith's, it takes what it takes. If the time is too long, look for a used one, if you want custom, hand built, in a one or two person shop, people can olnly work so fast and produce quality without getting burned out. If I order one, I'm hoping it'll be 6 months or less, I'd probably wait up to a year.
With Benny saying 12/16 - I'm fine with that - it's art, with a waiting list, and I'm at the end
