    When I picked up my 4th gen glock 27 I had the shop install nite sights. When I looked at the package I noticed the sight were for a 20,21,29 or39. I have shoot about 300 rounds at the range and I hit the traget dead on as I would with my stock sights. I don't know the difference in the sights between the models. Should I take it back or leave while enough alone?

    The sights you have are taller. If it is dead on, I would be hard pressed to take them off.

    The height of the rear sight for the 20, 21, and 29, should be .272". The G27, and G39 should both be .256. I'd measure the sight -- perhaps they had two empty packages sitting on the bench and he grabbed the wrong one. Also, at what distance are you shooting? At 7yds, a rear sight that is high by .016", would result in a POI that is higher by only .7" -- that can be really tough to see, especially since a Glock at less than 25yds should normally shoot very slightly low.
