I have read several places that adding a light, or light and laser, to the Picatinny rail of a Glock can cause it to jam. I don't understand how this can be? I can see that adding a light or laser to the slide might add enough weight to affect the ejection system, but I'm at a loss for a light...
I dont have a picture of my SFX200. but here are pics of my SF P series, and SF M-series with various heads.
60 - 120 lumens
250 lumens with anti-personnel pokey attachment
850 lumens aka the "sun"
