Universal Holster for UM3 Sight Mount Black, Left Hand, Paddle

• HOLDS ZERO AFTER REMOVAL: CC-machined mount keeps your red dot sighted in even after repeated removal and reinstall; no re-zeroing when switching between optic and iron sights
• TOOL-FREE INSTALL IN UNDER 30 SECONDS: Thumb-tighten clamp attach or detach with no tools, no drilling, and no gunsmith work; preserves factory iron sights and original slide
• UNIVERSAL PICATINNY FIT: Fits most pistols with a MIL-STD-1913 Picatinny rear sight rail (Glock, Springfield XD, S&W M&P, etc.). Use UM3X for pistols with a machined-out rail center
