I have now used the third Armalaser SR3 unit for about a month. I know this is a short period of time, but need to keep this thread going and those interested need an update.
After about 100 rounds and a couple of weeks of cycling the switch each day, I have no failures.
As I stated earlier this may be due to continued R&D on this product. I also noted that the Armalaser web-site now lists a few styles of holsters designed for the SD-SW Sigma.
I would be interested in hearing if anyone else has a comment on the SR3.
Thanks
