I shoot for bullseye accuracy with all of my guns in my old age. (I used to shoot tactical, but I enjoy the slower pace and challenge of chasing the X ring now).
If im not mistaken, the Scorpion pistol has a 1:9.8 twist rate. That is prefast but not uncommon. I have found 147grn 9mm stabalize better and will have a marked improvement in accuracy here. Premium ammo can also make a deference here in a big way. With some work, you can probably half those groups, expecially with a scope or 1MOA dot.
