I didn’t have to bend anything on the tang. I did have to modify the top of the synthetic stock so the tang fit. I took off a little at a time till it fit. The forearm fit with out modification. I also shortened the back of the stock a little for a shorter length of pull. I could go a little shorter before running into issues with the action spring in the stock. If I did go shorter I’d have to find a different butt pad.
Something to keep an eye out for if you have a single piece carrier is getting a 2 piece one. They can be hard to find and expensive. The 2 piece carrier allows you to load the shotgun without having to press the lock button on the left side. It also has the nice feature of locking the bolt open when empty. Auto loads the first shell you insert into the magazine if the bolt is locked back.
