I love FN rifles. I have a PS90 , and previously owned two other PS90s and a FN SCAR 16. And, I have read that the 509 is made better than the FNS… But… After this thread, I would not buy an FN handgun again (I owned an FNP years ago) : https://pistol-forum.com/showthread.php?24700-So-I-broke-my-FNS-9L
Granted, the thread is 24 pages, but worth reading in its entirety…
There seems to be an issue on the FNS series on what the lifespan of the gun is, and the maintenance schedule (which FN won’t release). And, they denied a warranty repair because the guy didn’t follow a schedule of having the gun checked BY FN every 2k rounds. That is ridiculous!
As someone on that thread said:
I realize this is not an actual maintenance schedule, but the FNS manual does say the gun should be checked by FN or a gunsmith every 2,000 rounds. Yeah, I know. That’s what it says, though.
Don’t do that, and they can deny a warranty claim it seems. I don’t know if this new Fn pistol is treated the same as the FNS series, but this is just pure ridiculous…
Another comment on the thread:
As I read that manual, with its horrible grammar and lack of punctuation, your pistol needs to be inspected by a certified armorer every 2,000 rounds OR every year. It does not say “whichever comes first.” The BS about how your pistol is such a finely tuned machine that your neanderthal mind can’t possibly comprehend the complexity, leading to its certain destruction if you do more than field strip pisses me off so badly that I would NEVER buy any FN product, EVER. Sure, you’re not a certified armorer, and I’m sure it’s more complex than a GLOCK, but, sure as a bear shits in the woods, I wouldn’t own a pistol that I have to ship off to the mothership ON MY DIME every couple of weeks/months.
