Trijicon rmr great sight - Trijicon ACOG Mount RMR Adjustable Red Dot Sight w/ MOA Dot Reticle

This is the second pistol RMR I have used and it came recommended from a friend. The first sight wasn't a Trijicon but a less expensive type that was junk. Also gave up on putting a RMR on my Glock 41 MOS. But after my friend's recommendation and seeing his Trijicon RMR, I gave it a try and wasn't disappointed! The unit is very well made, rugged, and operates easily. Installing it was pretty easy, just had to grind down the provided mountin screws to not go past the Glock mounting plate, you can use spacer washers instead. The only negative is the cost, but that seemed to be an investment in safety and quality, so it wasn't too bad.
