RE: RMR Issues
First of all, I will say that even as good a Trijicon is, anything man-made is subject to problems.
There have been a few problems reported with RMR's on WarriorTalk, but Trijicon took care of them right away.
TSD Combat Systems has spent a lot of research hours and $$ on properly milling slides and mounting the RMR. According to Gabe Suarez, they "surpassed 1000 units quite some time ago".
IMO, perhaps some of the RMR issues that have recently cropped up have occurred due more to people wanting to get a piece of the milled slide pie and haven't spent the time and money to research the details needed to do the job correctly.
Gabe posted an email from someone who had a slide butchered to the point that it would have to be replaced by one of these, merely to save $50 over the cost of a TSD unit. This 'gunsmith' wouldn't return the customers emails or calls either.
While I find the JPoint to be a less-than-desirable RDS for mounting now, I have been well pleased with the mounting job TSD did in the early days of their service. They will no longer mill for anything other than the RMR, as they have found that the other sights do not hold up as well as the Trijicon units overall.
If you are getting into having a pistol-mounted RDS, do your research. And don't be a cheapskate.
