I just bought a Kahr CW9 and i love it. I purchased it used for a great deal, took it out the next day and shot wonderful for what it is. Well a couple days later i dropped it on some concrete and it nicked the front sight. Took it out today and it was shooting HORRIBLE i couldn't hit the broad side of a barn! Now i know that the sights are fixed but do you think that me dropping it from 4 feet on concrete right on the sights could have caused this? And if it did cause it do you think lining the sights would fix? Or should i just get new sights? thanks for your help
