I am posting this reply to this old thread because another wave of these guns are hitting the U.S. market and many buyers are discovering that the stock front sights are useless and want to know their options.
I recently got a Beretta 92S and quickly found out that the stock front sight is just not usable. I sent the slide to Tool Tech Gun Sights in Oxford, MI and they replaced the sights with Trijicon HD night sights. They were able to remove the stock front sight and put in a dovetail for the front Trijicon sight. Just got it back today and it looks perfect. Going to take it to the range tomorrow. It was not free; far from it, but I look at it this way: If money is tight, shooting is the WRONG hobby, and if money is tight and you insist on shooting anyway then you need to just buy a used Glock 19 and leave it at that. Total cost, by the way, for the Tool Tech work was $293 including return shipping and they did GREAT work. Really nice job.
It is a nice 15+1 round gun, uses the standard and commonly available Beretta 92FS magazines. It is a little heavy for primary carry duty but a nice gun nonetheless. Nice in a "I don't really care so much what happens to it" way; maybe good for carrying stowed in the truck or keep in a quick-access safe in the den, or whatever. It just never hurts to have a spare gun, particularly if it can be one that you do not feel compelled to treat like a piece of crown jewels. But the sights have to be usable or there is no point to owning the gun at all. I read what I could find on the Internet and concluded that my best option would be the Tool Tech route.
