Alas, you two are right ... omniguns have the little gagdeteer only icon.

I think Janette dropped a Frontier gun for me once. But I normally don't use modern weapons.

My real problem is toting around a bunch of ammo like a packrat and being unable to use it, and unwilling to play a gadgeteer which could just stuff everything in the Omnigun. Picking up every pile of stones I find is a real back breaker.

Phasers come in a few places, but the easiest way to get one is to reload Jan-Ette just before you talk to her. Never took me more than 10 tries, and sometimes i also got Light Shield.
