So I picked up a 2nd gen Glock 19. No Austrian proof marks, pig nose included. Looks as if it was updated internally. Sights are still original and plastic is starting the wear. So Here's what I have in mind? 1. smooth face trigger bar 2. - minus connector 3. laser max guide rod 4. plug for the bottom of the frame 5. XS big dot sights Later send it off to have slide refinished? Or do I leave it stocked and maybe just go with steel oem sights?
