Ha! I missed your reply earlier. Every time I hear about Benny Hill the gunsmith/3 gun guru I start hearing Yakety Sax go through my head. I spent many an evening watching that show with my Grandpa. Probably explains some things about how I turned out.
That barrel would work, but I want one threaded for chokes so I might as well just cut and thread the one I have. I've seen guys have problems knocking over steel with a cylinder bore gun. Plus, I'd like to stay a little longer than 18.5. Cutting my barrel before the ports will get me to 22". The big problem is that Mossberg doesn't offer unported 930 barrels except in 18.5".
I picked up the gun a few days ago but haven't had time to really look at it until now. Overall I think it's going to be a good 3 gun rig. It's very light, and from what I've read they're very reliable even with light loads once they're broken in. They're supposed to be soft-recoiling, too, due to the gas piston design. The bad news is it's going to need some work to be ready for 3 gun. The big thing is the lifter on it is like a set of Chinese fingercuffs. When you try to load fast it grabs your thumb and won't let go. I tried loading fast a few times and ended up with a sore thumb. I'll have to weld it up to get rid of the gap that's catching my thumb. Luckily, I can do all the work myself except for cutting & threading the barrel, so once I'm finished I should have a shotgun that can shoot better than I can for about 1/3 the price of a competition-ready Benelli.
