Does anyone know why this ammo was discontinued, or where to get any? It's 150 gr HST "micro" 9mm, it's designed for short barrels. Also I'm interested in the 38 spc HST micro, it's discontinued also. I have some Buffalo Bore 158 gr 38 spc +p LSWCHP 1000 fps, but I think the recoil would be a bit much for an airweight J frame.
