Did you have to manipulate the gas ports or just change the port settings?The Saiga 12, for three gun shoots. Bought it at a gun show in Tyler, Texas, in September. It has been an experience getting the gun to reliably shoot light number 8 shot shells. It does, now.
I'm more interested in the Cobra. You'll have to tell us how it is.
Seriously? I'm going to throw it into the fender bag of my ATV as a survival resource.
BTW: the XD40 is my fourth XD.
