For defense I prefer hammers as long as there is a mechanism to keep the firing pins behind the receiver face until the trigger(s) is/are pulled.
I like hammers because of the lack of compressed springs (yeah, I know it is movement cycles that wear out springs, not extended compression time) and the very visual indicator of gun status/readiness.
I have a 12.5" barreled Norinco (in Canada this SG was called the Dominion Arms Outlaw) SxS. Barrels are Modified choke. I would have preferred cylinder so that flares and bear bangers could have been fired out if it without the risk of the flare stopping at the choke.
It is a pretty crude piece of kit but it goes BANG everytime, never fails to open/close, shells are easy to extract and it is SHORT. I mean really SHORT. SHORT enough to make antigunners cry and Fudds to point their fingers at me.
It was only $225 new, delivered to my house. Cheap enough that I don't care about it and I can leave it in my truck (properly stored, compliant with the law) 24/7. It's been in the locked modified briefcase below for seven years and no rust.
I had the misfortune of being on a remote northern highway where a deer had been hit by a truck and needed to be put down. None of us had a gun nor an ax and it was dispatched with a tire iron. Every guy there swore that he'd keep a gun or an ax in his truck after that. For me, for only $225 this is money well spent.
It has badly regulated barrels ( I bet many SxS's are the same). The right barrel shoots on line with the bead but around 9 inches high at 25 yards. The left barrel is also 9" high but also 11" left of the bead (tested with slugs).
I solved this by JB welding a higher height, green magnetic TruGlo tube over the bead/rail and then JB Welded another red tube to the left of the green. I use the green for the right barrel and the red for the left barrel. This has improved the POI with respect to the POA. Bubba RULES!
So put me down for hammers.
Shane: A gun is a tool, Marian; no better or no worse than any other tool: an axe, a shovel or anything. A gun is as good or as bad as the man using it. Remember that.
