I have re fallen in love with my Glock 27 as of late. I was having problems shooting good groups with it using the Glock factory sights. I recently came across some Glock OEM night sights for it and installed them the other day. These things made all the difference in the world as for accuracy. First shot at 15 yards was perfect right through the paper targets teeth using my 180gr gold dots. Now its off to buy a Glock 23 once my NC permits come though on Tuesday, I got a line on one for $398 new with night sights. Oh the joys of the LEO / MIL discount.
