Took two new aquisitions down for a little test fire today. A PT-911 and a PT-917, both new, never fired pistols. Both pistols seemed to shoot straight, but low when the three dots were lined up. If I shot more towards the lower center of the front dot or just over the target both pistols were dead on. Kind of ticked me off, but on the way home I got to thinking maybe it was me, not the pistols. All of the other fixed site Taurus I have purchased have been dead accurate out of the box, but these two are the exception. Two in the same day....could it be I was having an off day? Once I made the adjustment both were DAA.
