Bought a new polymer frame, steel slide, 9 mm from a reputable manufacturer (not S&W, permit me to not say the brand for now). It is reliable and accurate, but shoots to the right (2 or 3 inches at 10 yards). I am a lefty so I asked a righty to shoot it--it shot to the right for him as well (and he is VERY experienced). I moved the rear sight waaay over to the left (as much as I could without it hanging of the side of the slide), and that brought it almost back to center. But now it seems I need to consciously flex my wrist to bring the front sight into alignment
I looked at the front of the gun, and noticed the hole in the slide from which the barrel protrudes appeared slightly to the right. Measured it with a caliper and it seems about .015" to the right (the left edge of the hole was .20 from the left side of the slide; the right edge was .23 from the right side of the slide).
Does this sound like whining, or something in my imagination? Or does this sound like a a real mfg defect? I do not know what tolerances are expected. Are there more tests I should do or measures I should take?
I will go back to the manufacturer for service if that seems called for. Again this is not a S&W but you folks here are so knowledgeable and level-headed I thought I would ask here for advice. Thank you!
