My Mk3 is not accurate at all. I usually shoot it at 7 yds and accuracy sucks. Like 4 inch groups offhand at 7 yards. I dont think its me because I can put 5 rounds from my Sig P226 in about a 2 inch group firing pretty quickly. What could be wrong here?

Ammo choice can make a big diff from gun to gun.  What have you tried so far?

Barrel could be leaded.  When's the last time you cleaned it?

Mine will lead with as few as 50 Rem Thunderbolts. Doesn't lead with any other brand of ammo.

The trigger on the mark 3 sucks . You can fix the trigger and make the mag slide freely with a washer on ebay for 8 bucks . Really helped mine .
