Great slide - Zaffiri Precision RTS Glock 19 Gen 3 ZPS.1 RMR Cut Slide

Fit and Finish on this slide is excellent.. Definitely one of the best looking and functioning slides on the market.. with all the slide serrations not only do you get a very aggressive look you also get plenty of real estate to grab on to .. Zaffiri also has the best rmr only optics cut since it comes with posts giving you the ability to get more threads of the short screws holding onto the slide and the overall fit is tight with little room for the optic to have a chance to work loose
