Does anyone know where I can get a Factory Rebuild Glock 19 (Gen 2)?
I don't know about factory rebuilds but CDNN is selling some trade in G2s. $360. Replace the springs. With shipping, transfer, new springs, mags you're looking at $450+. If you can find one local that'd be your best bet.
I bought a new G19 a while back for $469 out the door with two 15rd magazines at the Eastman show.
Adventure Outdoors has them all day long for $499 + tax.
