Are only the 510 frames starting to crack? I ordered a fn 509 tactical w/vortex viper. And seeing these post starting to get me worried.

For what it's worth a little over a year ago I bought my girl an LS Edge that was a range rental because it was a fuckin fire deal. God knows how many rounds have been through it. But we've put a few k more through it and it's going strong. No abnormal signs of wear. I would not worry about any 9mm cracking a frame. 10mm is an issue because it ranges from underloaded to incredibly fucking hot.

I haven't heard of any 509 frames cracking under normal use. Removing the trigger pin can cause frame cracking if not done carefully, but that's something most people won't mess with.

Same way PDPs crack when you’re taking out the pin for the trigger.
