Where to get a rear sight installed on Beretta 92

[S&WMan]

I bought the Beretta factory adjustable rear sight for my Beretta 92FS. I tried to drift out the stock sight with a brass punch but it won't even move. Anyone know of a smith who does work on Beretta's or someone who may have the sight pusher tool for this gun?
TIA

Check out Greg Derr in the dealer section, (Derr Precision)....

use a bigger hammer and a wooden dowel.

Any decent gunsmith can do that for you. Try Greg Derr or David Santurri.
