No, it's not true. If you're foolish enough to try to use a pusher to remove a sight that was likely installed by a hydraulic press, then you shouldn't be touching my guns. Some Kahrs are very, very tight. Some can be tapped out with a punch and hammer.
If yours is very tight (as in, taps with a hammer and drift aren't budging it at all), these instructions will be of use to you. I have not measured to see if the front dovetail is tapered, so if it is, push the sight from smallest to largest :
Take a dremel and cut through the factory front sight post. Get a hand held metal hack saw and continue the cut, going almost down to the slide. Spray penetrating oil on the front sight and let it sit for 5-10 minutes. Get a nylon drift, or a brass one covered in non-marring material like electrical tape, and give one side a good tap with the hammer. It will break the sight in half, and the factory sight comes out easily.
To install the new sight, get a smooth cut hand file, and give just a couple passes on the bottom of the sight, and try to push it in by hand. Continue to do this, and check often. You want to be able to install the front sight by hand about 1/3 of the way. After this, tap it home, and take your time to measure and make sure the post itself is centered. Measuring on the end of the sight will not pass the muster if you want to do a precision job.
The rear sights should tap out very easily compared to the front.
Remember, don't rush anything. It will show horribly in the end product.
