Do you have a source for this? It would definitely be worth waiting for!
I don't think $55 is too expensive...only $49 if you buy two. http://www.berettausa.com/en-us/beretta-g-lever-kit/As far as the G conversion goes, the rumors are that the conversion is NOT going to be cheap. Possibly as expensive as the Wilson version.
Rumor has it that they will be available next Tuesday
I have the 96, but only because it took it to settle a debt. I periodically look around for a 92 slide to put on top of it. The 96 frame will feed 9mm, the 92 frame won't feed .40...that is why the old 92/96 Combo set came with a 96 frame.
If you're reloading .40 anyway, you can load light enough to reduce battering the frame. I've been shooting 165gr Xtreme bullet over 3.5gr of Clays and it is very soft shooting
