There has been a trend recently to trying RDS on autopistols, mostly Glocks and M&Ps. I have seen a lot of good work done and written up on another forum (14 pages now). It looks like the hot setup will be the T1 on a good mount, just like on an AR. There is even a new Safariland duty holster being developed for pistols set up that way.
I have not yet moved that way for a lot of reasons, mostly money. I have, however, followed the information with real interest. It seems that a good bit of dry practice presentations are required to get used to the dot. Until enough have been done, it is a frustrating time, but after - good to go.
I am sort of thinking of one more .357 revolver project, and have to admit that a 6" barrel with some sort of optic for better long range utility has some real appeal. Again, not a front burner project.
