There is very little information available for these sights on the internet so I wanted to get a thread started on GT for anyone who might be curious about them. Jason Falla of Redback One Training Systems partnered with Hilton Yam of 10-8 Performance to create these sights. The concept was to take an already great platform created by Hilton Yam and "fine tune" it to make the ultimate set of combat sights for the Glock platform. The RB1 sights feature a .125" wide by .215" tall front sight with a small .60" tritium insert set as high as possible in the blade without any sort of distracting outline. The rear is a plain black sight with a .156" square notch, both front and rear sights have 40lpi serrations to reduce glare. These sights are very similar to the 10-8 Performance sights, however only come in one configuration and size option and you must purchase them as a set. Some of the other main differences are the square rear notch, a slightly smaller and higher set tritium vial in the front, and the front has a slightly different side profile. I really like all these changes to the standard 10-8 sights and I think this setup definitely fills a niche for a lot of people out there. I placed an order on Tuesday and on Thursday they were delivered to my door by Fedex, excellent customer service in my opinion. For anyone who has any previous experience with 10-8 sights, the quality and craftmanship are both top notch. Weather has not allowed me to shoot with these yet, but just from dry firing and a few presentations around the house I can tell that the .156" square notch in the rear coupled with the thin .125" front blade is going to be an extremely fast and accurate combination. I replaced a set of standard 10-8's with these, so the transition should be quite easy and after I get some trigger time I will report back with my "performance" impressions. For now here are some pictures. The sights can be purchased here.
