Picking up a PD trade in G23 (2nd Gen) this morning and was wondering what if anything should be done prior to carry duties. (I had read about some replacing the recoil spring) Most of the other glocks I own were bought new or like new. This is the 1st that has any real age to it. Looks to be in 85% or so. Plan on this one sharing CC duty along with the G38. Thanks in advance.
