The ever-popular GLOCK pistols have a longer rail with the cross-slot positioned towards the front. This causes a less than ideal fit for many universal accessories. This C5L Custom was designed specifically for GLOCKs by the expert engineers at Viridian. It fits perfectly on the 17, 19, 19x, 22, 23, 31, 32, 45, and 47. Viridian has collaborative relationships with the major gun manufacturers allowing for the ultimate custom fits on the custom C Series and also the extensive line of red and green E Series. Nobody has more custom fit accessories than Viridian and nobody does it better. SAFECharge is the new, gotta-have, ultra convenient rechargeable power bank system that is ready when you are. The magnetic connector makes it a snap.
