One rendition of a must-have glock upgrade, done right - TangoDown Vickers Tactical Glock Slide Stop

As far as the amalgamation of Glock upgrades considered necessity for making "Glock Perfection" more, uh, perfecter; this slide stop is a good example of a healthy medium between low profile accessible controls. First impressions were modest. Simple packaging with list of compatible models for that particular slide stop (they sell a few now), and the product itself. The lever was clearly stamped like the oem component, free of burrs or irregular stamp work. The spring was securely fastened to the lever and was of good strength and orientation. The finish appears to be oxidized matte charcoal, with light scrathing but otherwise free of imperfections. Install was simple, and the lever juts an eighth of an inch on the top, while conforming to the frame towards the bottom of the tab. Not too much material to negatively effect holstering or concealed carry; just enough for a proper and consistent purchase on the slide stop. Has performed flawlessly through 2500 rounds. Feel is subjective, though it does in my opinion make manipulation of the lever easier to use and more tactile. All in all, definitely worth it.
