This thread is dear to me. I have 2 mdl. 12's....A 20 ga. from 1957 and my Dad's 12 ga. 2 bbl. set(32" solid rib/27" cyl.bore) that he gave me in 1978. I also have a near perfect 1897 with a 32" bbl.. These old guns are dear to me and I hunt with all of them. As far as a 12 or 97 blowing open....doesn't happen.
