Mine is a Type F. I followed the conversion instructions over on the Beretta forum and converted it to a Type G this morning. Type F is a safety/decocker, Type G is a decocker only.
The conversion is awesome. I was set to spend $70 on the conversion kit. Then I found the instruction for a DIY job. You just remove the safety levers from the slide, remove a ball bearing and spring from the left safety lever (this is what keeps the safety lever held down when it's engaged), and optional- dremel off the hook on the right safety lever that engages the trigger disconnect.
If you don't remove the hook, it really doesn't affect function, but it's not a true Type G then.
Anyways, it was really easy and came out great. I HATE slide mounted safeties, but I don't mind a slide mounted decocker at all. Flick the lever down, decock the gun, and it's ready to use again in DA.
