GLOCK pistols are known for their popularity, but their longer rail with the cross-slot positioned toward the front often creates compatibility issues with many universal accessories. Recognizing this challenge, Viridian’s expert engineers designed the C5L Custom specifically for GLOCK pistols. This custom-designed accessory fits perfectly on GLOCK models 17, 19, 19x, 22, 23, 31, 32, 45, and 47. Thanks to Viridian’s collaborative relationships with major gun manufacturers, the C5L Custom offers the ultimate custom fit for GLOCK pistols, as well as Viridian’s extensive line of red and green E Series.
