The 1900 has a snap on forearm and only one wood screw on the trigger guard. Couple of years ago I bought a F grade with a 2X4 looking forearm, 12 1/2" stock. I added on to the stock and had Bachelder install a semi beavertail forearm. Wish I hadn't , with their style of latch it keeps wanting to work for forward of the metal hardware. Must have been why they never offered a beavertail forearm.
