I've reviewed a few threads on WMLs, but none of them touch on what I'm looking for, which is a basic premise or thought process on using these lights. I currently run the Surefire XC-1 on my G19, and I have a INFORCE APL on my back up G19. I'm considering the INFORCE APLc Glock for both my guns, but I would like to get input on the use of these lights vs the HHL. I carry both the WML and a Surefire BACKUP, and would use either/both depending on the circumstances at hand. That said, I'm not a LEO or special operator, so I don't necessarily believe I need to try to be. Would just like to get some insight from those who have experience and/or who have given this some serious thought as to how to employ these tools in given situations.
