You’ll have to look on eBay for the latch and other parts for lights of that era.
Even the dual battery ones were pretty weak compared to modern stuff, although you can upgrade with LED P60 inserts.
But beware, not everything labeled P60 is truly direct match.
The grip tape switch was rudimentary by today’s standards. And prone to wear and break at the wire origin. Your weak hand thumb could work the slide switch, but left you lightless when firing one handed.
The holders of the era were made for either the one or two battery version, or could be heat gunned if too tight, a compensator was added, etc.
The issue holsters would also typically end up breaking the thumb strap at some point.
The next Gen lights had a better activator grip, less chance to break the connection, etc.
Keep in mind they were made for the M9 type frame, with the slanted dust covers variant seen in civ and LE later frames not the right fit for them.
And let’s not even talk about lasers of the era.
