Well.... once again I disagree with this hooplah..about Glock's and tatical lights. Is there something to it? Really? Is it a certain type of light?... I dunno. I do know that I've shot my
G23 (that's right .40 cal) with the standard Glock tatical light well
over 1500rds without a single jam, malfunction or hi-cup. Maybe I'm the only one in America that has Glocks that work like they are suppost to. I dunno.. I shoot my G23 and my G27 a lot and amazing they run flawlessly. And as far as recoil.. at least out of polymer .45's, like the H&K for example, the .40 ain't any worse. I'll try to do even more research and evaluation with my tatical light or others if I can get more ammo.. after trying to buy everything I can before BHO gets started

. And the only other thing that comes to mind would be if someone was shooting some of the very first Glocks to have lightrails cut in them. Perhaps, they were cut at a time before the deminsions of what most light companys are using now. Even though I have shot the crap out of all my Glocks (yes mostly .40's too) they are mostly all the newer.. Glock models.. only 2-4 years old.
