Vickers Tactical perfects the For Glock yet again. Having difficulty executing fast reloads with the stock slide stop? Extended slide stops locking the slide back with rounds still in the gun due to your shooting grip? Try the VTSS and never look back. Extensive prototyping and testing created the optimum slide stop shape enabling positive slide lock and release, especially with gloves. Precision stamped and formed from 4130 chrome moly steel with durable hard coat, the VTSS will outlive your For Glock. We recommend professional gunsmith installation only. Fits For Glock models G17, G17L, 18, 19, 21, 22, 23, 24, 25, 26, 27, 28, 31, 32, 33, 34 and 35 FITS THE NEW MODEL 30S
