I dislike the assumption that because a 74 can hold a large mag, the owner is going to fire a dozen rounds Rambo style...
It is an assumption right out of the gun banner handbook.
I own a Saiga 5.45. It sometimes is kept in the HD role, loaded with a 10rd mag of Hornady Vmax.
While my go to HD long arm is a semi auto 12ga with #4 buck, I have long been a proponent of the carbine for SD, and would not dissuade anyone who who feels more comfortable with one over a shotgun. It is certainly better than a handgun.
Still waiting for my Flashback...I would like it now, please.
