Sight pusher tool

So I was wanting to move a rear sight on my 1911 LDA Para Ordance 7.45
I gives it a nudge with an automatic center punch.  Nada
couple more nudges with the punch.  Nuffin.
So I am thinking wonder if they make a tool to push that.
Yup,  but BOY are they proud of it. 
MGW makes one like this:

anyone got one of these taking up valuable room in a drawer?  Would you consider selling it or Loaning for a week or so?

you can try a brass punch, or even a nylon one sometimes works, but some sights are tuff to move, we broke two aluminum drifts trying to change the front sight on a beretta 92

make sure it doesn't have a locking screw somewhere...

The one sold by glockworks is cheaper & should do the job

Dan, secure the slide in a good vise.  Those sights are put in with a hydraulic ram and are installed from R to L.  There shouldn't be a taper to the dovetail cut, but............it's a Para.
I use an aluminum drift to move sights after the slide is secure.  If you're still having a problem give me a shout and I'll see if I can do anything else to help over the phone.

I've used a machinist's vise and 1/4" cutting tool. Put the slide and the tool in the vise- tighten to move the sight. The slide sometimes wants to twist so this technique isn't always effective.
