I just picked up one of the SBR versions of this gun, received it yesterday. Today I put about 100 rounds through it, right straight out of the Garbage Jar. That's where leftover .22lr cartridges go to die, from the tail end of boxes, found in shooting bags, etc. I have only the one magazine so far, so it was shoot ten, load ten, etc.
I had one stovepipe failure, and it turned out to be the live cartridge that jammed going into the chamber, not the empty coming out. Everything else cycled and fired perfectly. That's ten magfuls with very few instances of two consecutive rounds being the same make and model, with just the one failure, out of a brand new gun. I was pretty happy with that. Plenty of those were standard velocity and even some subsonics, made no difference. I foolishly did not make note of what the single misfeed was.
Obviously wasn't monitoring accuracy too closely with that mixed bag. At fifty yards, with the irons, my group...yes, just shot the one!...was about 8 inches. I will be mounting a scope for testing, and may even load up ten rounds of the same kind of ammo when I do...
The gun is heavy, but so short that all the weight is right between your hands and it balances nicely. The trigger is dreadful, long and creepy; it breaks more like an overripe banana than a glass rod. Overall, however, the feel is very solid and confidence-inspiring; I have owned a GSG and the difference is night and day. I also had a 9mm Kriss for awhile, and found it very ungainly and muzzle-heavy with that insane long barrel and shroud. This gun looks and feels like that gun should have; of course, if it had, I would have kept that one and probably not bothered buying this one, so...
I am normally very fudd-inspired in my tastes for guns; I like nice walnut and blued steel. Bolt guns are too high-tech for me; I tend to prefer single-shots and levers. But this is just a cool and diverting little toy, and I like it. It's not beautiful; a Kriss is a form-follows-function kind of thing, and this one...lacking the same type of functional system...is strictly dressed up for show. With a red-dot mounted, I think it could join my small collection of backyard pest eliminators. It must be blooded to stick around for long.
