I don't have this product, but noticed the description is leaving out some major points. You need to run BUIS on a pistol with an optic because as you draw your eyes naturally line up the iron sights, and when the red dot appears in the sight window you naturally transition to that. Without irons, you spend 1-3 seconds searching for the dot because there's no way to perfectly line the gun up and lose all the benefits of having an RDS on a pistol. BUIS ARE ABSOLUTELY NECESSARY IF ADDING AN OPTIC TO A HANDGUN. So if you can't afford or don't want to mill your slide to fit an RDS, this is the next best thing. I will add that having the sight that much higher over the bore does mess you up a bit, but it's far better than running without irons.
BALOR RDS Mount
"RMR is NOW COMPATIBLE WITH GEN 5 GLOCKS" The Micor is not.
Designed for the Glock family of pistols, the Balor Mount allows the user to non-permanently mount an Aimpoint® Micro T1 or H1 or Trijicon® RMR to their slide. Rugged, reliable and simple to mount, the Balor also offers a return to zero capability. The Balor Mount also includes an internal, limited back up iron sight capability, in the unlikely event the optic fails.
The Balor Mount will fit in the Raven Concealment Systems Perun, Eidolon, Phantom and Vanguard families of holsters.
*The Balor Mount is compatible with the following model Glock pistols, Gen 1-5. (G17, G19, G26, G34, G17L, G22, G23, G27, G35, G24, G31, G32, G33, G41) It IS NOT compatible with the Glock 42 or the Glock 43. The MICRO is not compatible with Gen 5.
I’ve tried every way imaginable to put a red dot on a Glock, the balor is by far my favorite method, first no milling, second the front sight doesn’t snag like the tall fsp’s do when you do a milled slide and the rear sight is completely out of your sight picture, I couldn’t imagine a way to improve this product I would say lower the price, but it’s a steal at $200 compared to milling a slide. I will not ever be using another rds mounting system on a Glock ever again.
