Hello, I am new to this forum and not sure if I have the right area for this post please forgive me if it is not. My daughter bought a new PT840c at a gun show last weekend for home defense. We took it out for target practice the other day. Shooting at targets roughly 30 feet and some 50 feet they all shot low about 12inches. Three of us shot the pistol with the same results so it wasn't just my daughter's aim. Instead of lining up the three dots on the sights you had to aim with the front post dot way above the rear sights dots in order to get on target. Is anyone else having this problem? Does Taurus make a replaceable shorter front sight or is this something that covered under warranty that Taurus will repair? Thanking in advance on help with this matter.
