Just a quick review - there was over a foot of snow at the range, and I almost got stuck. I only put 5 rounds of #3 Buck through the gun, and 25 total of #7 and #8. The gun was flawless and even the Buck was very manageable. I haven't shot a 12 gauge version, so I can't compare the two. Suffice it to say that, for the less than 15 yard distances the gun is intended for (house defense, possibly truck gun), there seemed to be plenty of power to meet my needs. I put a rail on top and installed a tiny CT green laser. I also have a Surefire Outdoorsman on a CDM mount. The gun was very easy to get on target and seemed pretty intuitive to me; the laser was also awesome and I can see its benefit in a dark situation. Even after watching a lot of youtube reviews and reading the posts here and elsewhere, I wasn't sure what to expect regarding recoil. I was very pleasantly surprised (it's a 20, but...) and can't wait for better weather so I can spend more time putting lead downrange. If this gun continues to impress, I may have to get another one - maybe the 12 gauge? I'm sure that Mossberg will be taking advantage of this weapon's success to come out with updates and other versions. Someone said a .410 would be great, but I probably wouldn't be interested. If anyone has both the 12 and 20, I'd love to hear your experience regarding recoil, etc. I sure hope my "new favorite" gun continues to be "legal" in the eyes of that three-letter agency! I may become a collector!
