Sorry, I was not trying to be a jerk.I find the issue with sight pushers is this, they tend to try and push the blade, which in many cases sheer off under heavy pressure. And if you are using a tritium vial, which is glass this can easily break the vial. I use a hammer and drift because I can shape the drift(brass) to only make contact with the base of the sight. I know most folks have trouble not from the hammer and drift part, but the holdng part of the process. Like someone already posted you need to hold the slide in a stiff padded vice, firm rubber or leather works great and leaves no marring. Overtight is no good either since you can warp a slide with too much pressure. If you have multiple firearms the vice and drift with hammer will also be cheaper since you don't need a new jig for each slide profile which is expensive.
