So, this makes so much sense I am shocked Beretta did it.
In a few previous threads there has been discussion on the Beretta 92 (M9) and one of its great vices, the combination decocker/safety. The issue is that when running the slide (such as during a stovepipe or when chambering a round if forced to carry it with an empty chamber) a person can accidently wipe the safety into the "on" position resulting in a dead trigger. It is also a step that can be forgotten even if you are carrying with a round in the chamber with the safety engaged.
Beretta addressed this flaw when it released the Beretta 92G. It is a factory Beretta 92 with a "decock only" lever on the slide. Basically, if you push down on it, the weapon will decock and the second you release it the lever springs back up into the "fire" position. The only "safety" is the long, heavy double action trigger pull...as God intended.
The issue of course, is that those of us that already had 92FS type pistols did not want to pay the money to buy another Beretta and of course, no police department and certainly not the department of defense would engage in the practice of buying a "less safe" pistol.
No Beretta is selling a $55 converter that will let you convert your M9 or 92 series pistol to a decock only configuration.

If I was the sort of person that would monkey with the guts of my issue pistol (in all seriousness I am not) I would swap the decocker out in a heartbeat.
