Yes, The Meprolight Micro RDS IS a pistol red dot sight with a very unique design; you are not required to mill the slide or purchase an optic-ready pistol slide. The rear sight contains an extension rail with a cut for the optic. The optic can then be installed and removed in seconds, offering return-to-zero capability. Hope this helps.

Brady, yes, it has patented quick-detach (QD) adaptor kit that easily mounts using the pistol’s existing rear sight dovetail slot; no drilling, tapping or need for a gunsmith. >>> meprolight.com/product/mepro-micrords/?ml=ML-880500
