I love it, thank you KM Tactical. I just received my slide in today and paired it with my Lone Wolf Tactical frame and it’s smooth as butter, can wait to put rounds through it. I want to show the picture of it but I won’t complain

Update on this slide. It’s failing to feed after every shot even when properly lubricated. When paired with a factory Glock frame it’s still failing to feed and isn’t properly cycling through. My next option is to run with a heavier guide rod and see if that’s the issue
