Thanks gentlemen. My neighbor has a 391 Trap gun so I will see if the 390 is the same. If not I will be in touch with you Mike. Its for a buddy of mine who has heart problems at a relativly young age. Alloy receivers and a sling might keep him chasing ducks and pheasants for a few more seasons.
MikeyLikesIt is correct they do not interchange. Thanks for your kind offer Quack-kills. There is a gunshow this weekend perhaps between the blowguns and bobblehead dolls I may find one. Thanks again. Bill
