Mine always seems to have cycling issues.
I have a benelli supernova which I like best.
Gotta set up the gas plug for the load used.
I've found that there are certain loads that the Saiga shotguns seem to 'like' more than others. I've never had a bit of trouble out of 'high brass' hotter loads. On the other hand, it tends to be sloppy with cheap low brass range loads. It's almost like an entirely different gun, between the two different types of shells. Luckily, the one it seems to like is the type you would use when it counts. I believe MD Arms makes an adjustable gas plug that allows you to compensate for the differing loads. You may want to look into it. They are inexpensive."I have a benelli supernova which I like best."
You can't beat a Benelli shotgun. They are awesome!
