My lgs has these. The Utility also has choke tubes. I have disassembled two. Workmanship is excellent. The gun is heavier than an 870 or 590. I bought the Stoeger 3000 because I got an as new one cheap. I said earlier that the Model 3000 has vicious recoil with regular buckshot. The gas operated 712 Utility should have less felt recoil. I can tweak the M300O to run with light loads. Doing the same with the 712 would require enlarging the gas ports and cutting a couple coils off the recoil spring. Both brands are designed with the recoil spring fitting over the magazine tube. I'm playing around with the Stoeger. Both guns are too much for me. If I were serious about using a 12 gauge for home defense, I would buy the famous Beretta 1301 and be done with it. Ending up with over $1000 in a Stoeger is easy when one begins customizing. Sad thing is the damn thing is still a Stoeger. I disagree with most folks and assert that inertia driven shotguns can be temperamental, especially when hanging stuff off of them.
