Uts-15, my wife and 12 year old daughter can shoot it without a problem, less than 25" total length, and 15 round capacity. 12 gauge power and 410 recoil, nothing to buy down the road either, light/laser built in, comes with breaching choke, and loaded with 00 buck still weighs less than 9lbs.
Anything less than 26" OAL is illegal.
Thanks for the info guys. I'll look into the Remington's a little more. I think I instinctively went to Mossberg as they seem synonymous with pistol grip shottys.
