Do not buy for gen 5 - Zaffiri Precision RTS Glock 19 Gen 5 ZPS.3 RMR Cut Slide

Start off by saying I heard alot of good things about Zaffiri Precision before I bought the slide.Got it for my Gen 5 G45/G19 RMR cut. Looked great felt great. 1st issue happened when I put the slide onto my G45 lower and noticed the trigger got stuck back a few times. Ok maybe just needs to be fired run a few times. Next day at the range 150 rounds through 18 miss fires!!. I was crushed not to mention how unsafe it was.The firing pin was hitting the bullet but not fully setting the round off. After some careful inspection of the Zaffiri slide which was for the Gen 5 I noticed it was not to Spec in several areas. Especially in the firing spring safety slot it was more rounded instead of oval like the Gen 5. Sent it back to Optics Planet waiting to hear on response hoping to get full refund or store credit. Love Optics Planet not there fault but dont buy a Zaffiri Slide for a Gen 5 Glock at least not this one.
