I've got a .45 M&P 1.0, made in 2012 with dead night sights. I'd like to get them glowing again.

There's no brand name on them, just M&P on the rear sight and the letter "S" on the front.

So I'm wondering who makes them so I can ship the slide off for new lamps. (I tried S&W customer support but they couldn't tell me as the gun was discontinued and that wipes out the on-line info they keep on each pistol, which apparently is accessed by the serial number -- who knew?)

Any help would be appreciated as I'd rather not have to spring for a whole new set of sights. (Of course I could just paint 'em up with some white nail polish and pretend they're just plain old 3 dots.)

You might give Trijicon a call and see what they'll do for you. SFAIK, S&W never relamped, they just replaced the sights.
