I don't know if M&J in Fortville has or can get/install those sights, but the 2-3 times I've been able to stop in there, the guy working (owner, I believe) has been quite nice/personable.
I HAVE purchased stuff at USDS, but that's quite a haul from your location. If I were to head to USDS from your location, I'd "make a day of it" and hit up several other greater-southside shops, too.
Where can I pick up a set of Trijicon HD sights for a Glock 17 and have them installed? Preferably in the NE Indy/Fishers area.
See if you can buy the front sight only and then just do it yourself in about 5 minutes. I don't like the confusion of three dots on my defense pistols, so I prefer the rear sight not have have tritium in it anyway. I have Trijicon HD sights on three pistols now and prefer the ones that I only used the front. You might think that the front sight will appear dramatically different than the rear dots in the dark, but unless you hit the front with a light, it looks pretty much the same. In the daytime it's great, but the colored portion of the front sight, yellow or orange, is a luminous type material that requires light to glow. Great sights, just some info for you if you didn't know.
EDITED (TWICE): You can find the front sight only on Optics planet for $67.99 and the tool on amazon for around $8. All you need past that is some blue Loctite and you should be set for significant savings.
