I have a low point of impact with my pt140 pro. 5 in. at 7yrds! The barrel seems to be canted down abit as you look at the pistol assembled from the side. Wear marks confirm this as well. I would hate to start removing material with out knowing for sure. Wondering if it might need a trip to Taurus. Bought it a few yrs ago and have only about 500 rds down the pipe. Wasnt real concerned till now since it will be latest my primary. Thanks in advance.
