If it is 9MM it probably does not like any ammo, in that they left the sights regulated for the 7.62 on the one I had and it did not shoot near POA. I only ran ball ammo thru it as I recall, it was a cheap gun, my only 9, and I did not want to spend money on premium ammo for the thing! I think it was kinda loose so it grouped more like a well worn .45 than a target gun anyway.
