John: Thanks for the info. I tried for a couple of years to buy choke tubes from Bernardelli but never got anywhere. Have not found anything else that looks like a fit. TruChokes had a small run of tubes that fit P. Bernies but I was not able to get any of those to test. The doubling is inconsisitent, and I just put the gun away rather than try to fix it at the time. Re the quality, it's actually a pretty nice gun and compares well to my Beretta 682 Gold Supersport of about the same vintage. Warschall's had a few new ones on the rack in 1995 tagged at $1900. I bought mine used from a frustrated clays shooter; maybe it was the doubling that got to him.
