I have a PT-145 with ~600 rounds thru it. While cleaning it after a recent
range session, I noticed some odd wear.
On the inside edge of the slide rail, just aft of the breech face there were
a series of small nicks or dings in the edge of the rail. As if something with
a hard edge had banged up against it. I hadn't noticed this during any
previous cleaning session.
The dings were easily felt with a finger, and a little work with a file cleaned
them up quickly, but I'm wondering what could have banged up against
the inside edge of the rail to cause this. Any ideas?
