Just thought I’d share… my 1301 came with the Mesa Tac pistol grip stock. I quickly changed it out with a GGG/Magpul stock. The Mesa has been sitting in a box ever since.

I’m planning on cutting down the factory stock on my Benelli, so I removed the stock to take measurements. I saw the Mesa sitting on the shelf and decided to try it on the M1… it didn’t fit. The trigger housing extends back past receiver about 1/2” which keeps the stock from fully seating. So the Mesa will go back to collecting dust on the shelf
