Pappabear, the G conversion is not really tough to do, if you have somebody helping. It honestly does help to have a third hand available when you re-assemble the slide.

But the actual G lever kit is not real expensive off the Beretta US website. And they are good about keeping them in stock.

It's just 59 bucks with free shipping: https://www.berettausa.com/en-us/beretta-g-lever-kit/
