I have a P365XL slide I want to change the front sight on, from Sig OEM to Ameriglo. I only change sights very infrequently, so my sight pusher is not very sophisticated, but I have had it for several years and it works fine for rear sight dovetails, on a very occasional basis.
I've secured the slide in a vise and tried a steel hammer and both brass and steel punches to move the sight in the dovetail, but it is held tight and will not move. I am moving the sight out, from right to left, looking down the slide from the rear, which is as far as I know the correct direction to push the sight out.
My sight pusher contacts the front sight, but it will not "reach" down into the front sight dovetail to contact the base of the sight. It will however just reach and contact the front sight blade, only. So my option currently to use my sight pusher is to push on the front sight blade, itself, above the sight body.
Is this advisable?
