Welcome to the forum. Glad to have another of our Millenium brothers on board.
May it be suggested that one read the FAQs board as well as any threads dealing with the PT145 and there brethren in the Firing Line, Concealed Carry, and Taurus Semi-auto boards. Just tocover it all the Smithing is a good place to go.
AW heck. Read all the threads at all the boards pertaining to the PT145 and ammo choices. ;D
