So I settled down late on New Year's Day with the Glock 19 Gen4 and prepared to make some alterations...
Ameriglo CAP sights to install, and to install them, I had a brand new MGW sight pusher and a handy front sight installation tool from Fixxxer, both of which I'd purchased from Amazon.
The rear sight came off in a jiffy and the new one went on almost as quickly. The front sight was swapped out in a jiffy, too, with the shallow magnetic socket of the Fixxxer tool being super handy.
I also had a smooth-faced trigger from a full-size Glock to put in, but I decided I'd filthied up my hands enough for one night and put it off for later. I'll put the trigger in this afternoon when I get home from the range.
