I called CSMC several weeks ago to check on my PIF first day order and was told it was "in the shop". I checked on the status of my friend's order placed a couple of weeks later and that is also in the works.
This time I feel the orders will be delivered on schedule which means the first guns should be shipped in April.
I ordered my gun with double triggers. My RBL-20 has a single trigger and the selector has the uncomfortable tendency to move when I fire the right barrel first. I've had the same problem with Model 21's and I know I'm not alone. Obviously, if I fire the left barrel first, and I have the gun now set up to do this, there isn't a problem. Since the RBL-16 is fixed choked, I don't have this option. My RBL-28 has double triggers and it's flawless. I love it.
These guns have an advertised weight of 6.25 to 6.5 Lbs. Hopefully, they will be within specs. The first two guns don't have a weight problem. My RBL-20 is slightly over 6lbs. and my RBL-28 weighs 5lbs., 13oz. with 30" bbls and BTFE.
