I took a box of Magtech.32S&WL out to the range to shoot thru my new S&W 431 PD and it would not shoot the ammo. It would leave a small dimple but not fire. The pistol will fire H@R .32 Mag all day. I read on line that you could fire H&R .32 mag, Long, and short thru this gun, is this true? It does not seem so right now. Please fill me in so I know what to buy. I am glad I did not have that in the gun when I need to save my life.
