I bought a cheapie Sight Pusher online for about $60. It's still easy to screw up a pistol with that. Remove from left side to right side and install from right to left side.
My post on the Sight Pusher:

Kahr dovetails are very tight and though some report driving the sights out with punches and a hammer, you could damage the slide and the sight. All force should be applied to the lowest part of the sight base. Too high and you can damage the glass Tritium vials and kill the glow!
The slide should be held firmly in a non-marring surfaced vise or the pusher. I use thick fiberboard... the separators from a wine case... to cushion the slide. I also pushed or installed slowly and made sure that the bearing part of the pusher didn't contact the slide grooves or the wrong part of the sight base.
I bought the Glock version of the Sight Pusher and made it work on the Kahrs. I was able to do several sights without any damage, though the instructions for some sight installation leave out a lot of proper steps and care out of the instructions. The XS Big Dot instructions only said remove material from the bottom of the sight base... nothing about some from the sides of the base. At one point i had to remove material from the underside of the tube part of the front sight because it was impacting the top of the slide and about to rip the front sight from its base!
I'll try to find the link for one of my posts about this.
This is not an easy procedure to tackle. Most guys would be better off sending their slide to Kahr or Trijicon for installation
Trijicon will re-lamp THEIR sights only for a pretty low cost. After 12+ years, I had my K9 re-lamped by them and it cost me about $8 to ship them the slide. They re-lamped the sights and returned the slide for $54... about $18 a lamp!

I'll post this and then go find some links to add in an edit.
One YouTube video on front sight installation:

Old post: I was perusing the Kahr.com site and ran across a pdf instruction sheet for installation of night sights. The file is available for download here:
https://www.kahr.com/Night_Sight_Ins...structions.pdf
It's pretty simplistic... DO NOT USE A PUNCH TO REMOVE THE FRONT SIGHT... or the rear... and removal is from left to right using a non-abrasive sight press.
Kahr emphasizes NOT using a punch and NOT pushing on the posts of the sights, to preclude damaging the delicate glass vials holding the Tritium gas. Any pushing of the sights should be done as low as possible on the BASES with great care taken to NOT damage the dovetails or the sight/slide finish.
Any sizing adjustments should be made to the sights, not the dovetails... with the exception of deburring the entrance edges of the dovetails.
I copied and pasted the page here and edited/corrected the layout, as it did not paste in normal layout.
I hope this is helpful. I've used a minimal press to change and install sights, BUT... I don't recommend anyone do this. It would be best to let real experts do night sight installation. Saving $30 or $40 won't seem like such a great idea if you damage the sights and/or your pistol!
If you don't have a "
Non-marking sight press", FUGEDDABOUTIT!

Here's where I installed the XS Big Dots, but the instructions made no mention of any procedure to remove burrs from the dovetails or the base of the sights. The 22 minute video does mention this, I believe.
