Aimpoint RDS and Pistol mounting PSA
Last year I finally got into the RDS equipped Glock game, using a ALG Defense 6 Second Mount on a Gen 4 Glock 22. About 100 rounds into learning the gun, the dot disappeared. I contacted Aimpoint, and they took care of replacing the pre 2009 well used and abused 4 MOA T-1 with a new 2 MOA T1. In the meantime I used another pre 2009 used and abused 4 MOA T-1 on that gun. It had no issues in the mean time.
A couple months ago, I received a testing model of the Raven Concealment Balor optic mount. I took the used 4 MOA T-1 and put it on the Balor and then mounted it on the Gen 4 Glock 22. About 200 rounds into it, well dot/dial broke. Again, I contacted Aimpoint. Aimpoint rapidly took care of warranty work on this, but more importantly for those interested in a Aimpoint RDS on a Glock, I received the following advice.
While there is no proof that the Aimpoint T-1 family is being killed on pistols, there have been more than one optic killed when mounted to a pistol. While researching that, Aimpoint realized that the majority of the T-1’s being killed were older with a certain tech improvement that started on the T-2 series. The improvement is seen when you remove the battery.
As you can see in the following picture, there are 3 “nubs” (for lack of better term) on the copper disc. This is the old tech.
This is on the new tech – starting roughly mid 2015 production T-1 family (2 MOA usually). This has 16 nubs on it. This is shown on a 2 MOA T1 I got last summer in warranty repair/replacement from Aimpoint. The other 2 MOA T1 I bought last year in the mid summer from a Aimpoint distributor doesn’t have the 16 nubs, meaning it was existing stock.
Just be aware of this if you happen to need a Aimpoint RDS for a Glock. For more discussion on Aimpoint RDS, be sure to check out the discussion on the various Primary And Secondary outlets.
