Was looking at night sights for the Glock and called a buddy who is retired LEO/SWAT Team Leader. Said one of his LEO buddies had 2 sets for sale. Ended up buying both, though I was only after the TFX PRO set he had ($65). My buddy installed them while I was there. First set of sights I've ever changed on a handgun since starting shooting handguns in 1980. Took a few shots to check zero, seems to be on the money. Will let you know how they work out. Another 70 rounds through 2 new mags I picked up from the LGS.
