For a reliable aiming point, equip the Zaffiri Precision RTS Glock 43/43X ZPS.2 Pistol Slide RMSc Cut. The RTS.2 marks the second major revision to Zaffiri Precision's popular Glock aftermarket pistol slide #43. The new geometry eliminates the rear lug and slightly lowers the front lugs, which allows the optic to be mounted in the exact footprint as the RMSc, Holosun 407k/507k and Sig RomeoZero slides. As such, this slide does not require an optic cut and does not change the overall width or height of the Glock. However, it does require a channel liner and screws to install. Therefore, the RTS.2 version does not work with Glocks 43 or 43x. Nonetheless, this slide offers a nice front end look, is compatible with Polymer80 PF9ss, and does not include channel liner. With all of these factors taken into account, the Zaffiri RTS.2 slide offers excellent quality and reliability. Add the Zaffiri RTS.2 to your Glock for a sleek aesthetic and an even more reliable aiming solution.
