Anyone ever change out a hammer in their 1911? I am going to have one of the PD armorers take my stock hammer off my duty 1911 and change it to a commander style. I noticed the pin for the hammer strut wa in their pretty good. Does it take a lot of beating to get it out? It seemed like they never took it apart in armorer's school from the way they talked. They certainly didn't do it the two times they inspected it.
