I too bought a CSMC Mod 21 [Sept 2007],a Grand American with IN MEMORY OF KOKO on the rib. Koko was the absolute best of all the dogs I've had and that includes a few Elhew pointers.
I received it on a Friday [Sept 2008], only three months later than expected, shot it on Sunday and shipped it back on Monday. They got it back on Tuesday and I got it back on, I think, Thursday.
I sent it back because it doubled! And if you fired the right barrel first, the left barrel would not fire. What puzzled me was when I spoke with Lou, he asked me if I had removed the stock.I had not.
The answer came when I read Shotgun Technicana. Unlike the English best guns which have a shoulder on the screws to prevent over tightening,Mod 21s can be over tightened and that can cause problems. You have been warned !
Other than the above the gun has shot without problems. Koko would be proud.
