My buddy got a Taurus Millenium sub compact in .40SW just a couple weeks ago. We have, together, put about 300 rounds through it since.
This thing is absolutely the most inaccurate gun I have ever shot. Consistently it shoots low and slightly left, but mostly low by four or five inches.
Ok, dont say its trigger finger because it isnt. Four different people have shot this gun; myself, the owner, another gun owner and a LEO buddy and it is the same with all four people. To hit dead center target you have to aim four or five inches above center at 20 feet target distance.
To compare, all of us shot each others guns which would be XD45acp (mine), Glock 30 .45acp (Garrett) and a Glock 17 (Stan).
In all cases, except with the Taurus, we each put very tight groups dead center of target. The XD, of course, was a slightly better group than the Blocks
Anyway, we know it isnt trigger. It shouldnt be sights. Sights are factory installed Heinie non-adjustables.
We noticed the barrel does not sit dead center of the slide hole (looking at the muzzle end unloaded of course).
What could be factors causing this much accuracy loss?
