Kahr PM445 installation?

[King Rat]

First of all, I only buy a front night sight. Two, I have a sight pusher, but better yet, I have a great gun smith. Takes him about 10 minutes. He stops what he is doing and does in on the sport. Low cost.

So what’s the reason Kahr sights are more difficult to install? Maybe because the internet says so.

I've seen this complaint about several brands. Maybe we're comparing it to those Ruger GP100 front sights.
