The Benelli M1 (or M2 or M3) is a nice shotgun, but I found that the stock was too long for comfort, especially when compared to my 870 that wears a shortened LOP Speedfeed stock. After some random searching of various forums, I learned that Ned Christiansen did a nice LOP reduction on the Benelli stocks, but given his busy schedule and various projects, only does this work in small batches on occasion. However, he was kind enough to share with me some suggestions and advice on how to do this
