Thank you tracker. The Glock 36 is distinguished by the absence of a picitinny rail which I think looks stupid. Yes, I know, gun owners like to follow LEO and military but I think the picitinny rail spoils the lines on the underside of the frame and barrel.
If it were an OPTION, not a problem. I would avoid it and order guns without the picitinny rail. Howevr, it is NOT an option (you know, like obama's government) and far too many guns (including kel-tecs with microscopic barrel lengths) feature this contraption.
For night useage I prefer my anodized black aluminum LED flashlight (weak hand over strong hand). And, when day breaks, my guns are not stained with that stupid rail!
