An interesting product I came across today at SHOT Show was the Suppressor Weapon Sights from AmeriGlo. The front and rear sights are raised which allows them to be used when a suppressor is fitted to the pistol. Conventional cylindrical suppressors usually block, or at least partially obstruct, the sights of centerfire pistols. You can purchase expensive suppressors, such as the Silencerco Osprey, designed to avoid blocking pistol sights, but for the majority of pistol suppressor owners a $110 set of tritium sights from AmeriGlo will solve the problem. Another advantage of these sights is that they allow co-witnessing with micro red dot optics.
Right now AmeriGlo is only offering these suppressor sights for the Glock platform. They can be purchased in a number of styles including 3-dot, 1-dot, steel only and with and without tritium inserts. The tritium. Hopefully they will offer these sights for other platforms in the future.
