I bought a TruGlo Tritium sight (Green front, yellow rear) from ebay for my Kimber a few weeks ago and was contemplating if I should try to change the sights myself or send it to a gunsmith to have it installed.
I called around a few places and most of them charged anywhere from 60-100 dollars to do it with a 7-10 week wait! These guys make a ton of money if they have so much work, either that or they need to train more apprentices.
Anyway, I decided to do it on my own to save the time and money. So I ordered a Hammer and Punch set and borrowed a portable vise from a buddy of mine, David and got to work. I followed the instructions on this really concise and clear video by a gunsmith who works for XS Sights :
here’s my vise and slide :
Knocked the sights from left to right with the brass punch and hammer, was a little tight but a few good knocks will unseat it. Just make sure your brass punch doesn’t scratch your slide.
Then installed the new front sight by filing down the dovetail until it slides into place about halfway then knocking it in with a non-marring polymer punch.
To remove the rear sight, I had to first unscrew the locking screw and then using a brass punch, knock the sight out. The rear sight was much easier, removing the screw was hard because it was glued in place using a thread locker.
Also, watch out for a spring that is underneath the rear sight, this holds something in place (I don’t know what that part is called), here’s the hole where the spring sits :
and the spring, I found this on my carpet by accidentally stepping on it, and I went, WTF is that? where did it come from? then I found a thread on the 1911 forums that explained it all :
all done! :
Now all I need to do is to wait for my thread locker to arrive and glue the sights into place. I also heard that you need to use some epoxy to secure the fiber tubes in place as there have been numerous reports that these sights come off while shooting.
