Cracked P30 slide upon sight install

[Spr1]

I dunno but now I feel very lucky not to have cracked a Glock slide with the force I've used to install a few Warren rears. I should be more patient with such things.

The sides of Glock slides are parallel, which allows one to clamp them quite hard. The P30 slides are tapered and open in the rear, therefore, if you just squeeze it in a vice, the slide is put in bending.

Ah got it. Duh. Thanks!
