Must have been a tad later than 94.
Prototypes were first made in 1997, a small number that appear to have been made for the USA market in 1998, I imported a 98 from the States. It's still the only one I know of in the UK.
The mainstream supply are dated 1999 and these are the Gen 1 models and are the most sought after.
Easy way to tell us by the serial number on the slide, body and normally on the mag base.
Typically a 1999 would begin T99.... and so on.
