I recently came across a pretty informative article online regarding laser sights that I want to share. The article is a couple of years old but still has a lot of valid information. It seems that green lasers are becoming more popular lately so I was interested to read about the difference between red and green. We make a lot of holsters for M&P Shields with Crimson Trace lasers and originally found it interesting that the green laser is shaped differently from the red. Come to find out the technology behind the two have some pretty big differences. There are also a lot of pros and cons to each one as far operating temperature ranges, cost to produce and how durable each laser is. If you have a few minutes, check out this article from OpticsPlanet.com.
