You may as well just go right to Pecatonica, as TOW sends most of their stuff to Pec anyway, so you will cut the time an cost down some. As has been said if it's a straight barrel, no problem, as you can adjust to where they cut the lock in. You may need to adjust the placement of the barrel front to back, or lower it, since you won't be able to move the lock position. Don't let me scare you, as we are only talking an 1/8 inch or less of adjustment. Pecatonica puts out a good product, and a number of suppliers use them.
