Hello fellow gunners. I need a light for my Glock 17 standard. I never thought I would need one, but after doing a bit of reading I think it's best for Home Defense. I'm leaning toward the Streamlight TLR-3. I'm not sure how it fits on the G17 though? Any recommendations? I'd prefer that the light fits flush and doesn't stick out past the barrel, but that's just preference. Thanks in advance.
