Bought a SB brace for my new Remington 870 Tac-14 20 gauge. I am in a wheel chair and first fired the gun a couple days ago. Even with just target loads it wanted to fly out of my hands. Hard to get a proper grip and shooting position from a chair. So I ordered a front forearm strap for it when I got home from test firing the gun, and about 2 hours ago purchased the arm brace.
