I've had no trouble replacing sights on a variety of handguns but I agree that where it can be used, a sight pusher is best. There is probably a youtube video on the subject for any gun you want to install tsights on.

I've also found that sometimes I have to use 2 different pushers on the front and rear sights on some guns because their geometry just doesn't play nicely with the tools.

Another thing to be aware of is that some sight channels are tapered slightly from one side to the other. It's important to know that because there's one side the sights will go out of and into nice and easy, and one side where things will be really hard or impossible. A little online research will tell you whether that's true for your gun or not.

Don't try to install tritium sights with hammer and punch - there's a very high likelihood you'll break the tritium vials and the manufacturer will absolutely not honor the warranty when they see punch marks on the sight.

Either make the investment in a good sight pusher tool (mine has paid for itself several times over, but I've used it on .....ahem....more than one gun), or take the gun and sights to somebody who has one.
