The Weatherby has a "benelli-style" magazine cutoff also.
The Mossberg and Tristar have an intergrated magazine cutoff that works simply by depressing the shell carrier up into the gun halfway while emptying the chamber.
*Tristar warranty is for 1-year they do all the parts and service for free, and 4 more years of free parts but you pay to fix it or fix it yourself.
*Mossberg is a 1 year limited warranty (not sure what that really means).
*Weatherby has no express warranty (but are known for having good customer service if it is their fault).
