Up until early to mid 2000 Geco brand 9mm was readily available. It was loaded with a 124gr gilding metal clad mild steel jacketed bullet. Geco brand 9mm ammo hasn't been available since around 2004.
Dynamit Nobel A/G of Troisdorf, Germany, made ammo that was headstamped Geco, DAG & RWS.
RUAG Ammotec of Switzerland now owns the rights to many of the European brands of ammo, including Geco, DAG, RWS & Norma to name a few.
The current Geco ammo is reportedly made in Switzerland, just like the new production RWS 124FMJ that's on the market right now.
I haven't received my shipment of the new Geco 9mm, but I expect that it'll be of the usual Swiss quality and more than likely will use the same gilding metal clad mild steel jacketed bullet like the older Geco and the current RWS ammo uses.
