Sorry guys, I wasn't clear. I ment steel (alloy) parts instead of plastic.
The frames are anodized alluminum except on the Billenium and the new steel framed Vertec without rails (unsure of the name).
Actually, with Beretta USA, it is almost impossible to know exactly what is going on at any given time. They change materials and designs and forget to mention it to anyone until you're looking at it at the gunshop.
Not all G models are the same, there are the Elite series, and some production G's. A couple newer models as well. The G line extends into their Cougar series too.
Most are limited to LEO except the Elite series. They're limited to LEO mainlly due to logistics in splitting up the high cap mags from the firearm.
The easiest way to obtain the production G models is thru police trade-ins.
The Elite series doesn't have a langyard. The cap is metal though. The G Decocker is metal as of October '01 production units. I had a bevel job done on the weapon, along with the decockers. They're definately alloy. Hell, recent productions may have a plastic... er, I mean carbon fiber barrel.
If you want to see Beretta's progression in the firearms industry, look no further than the 9000.
Sadly, I think I've bought my last Beretta.
Sorry about the unintentional mis-information.
