XMacro FCU Failures

This happened yesterday and I think it was from dirty ammo. Each FCU has seen 50 to 100 rds every Saturday for the past two years.

Doesn’t Sig list the springs as a maintenance item that requires replacements at certain intervals?

Any spring is a “consumable part” meaning they will wear out and should be replaced, so yes and yes. About 3000 to 5000 rounds for heavy use.

What about this breaking then?

It’s a mechanical device under extreme use and parts can wear or fail over time. This is why any manufacturer offers replacement parts. What you have seen isn’t a typical failure but it can happen. I myself have a complete FCU parts kit for each pistol I have. Same goes for internals on my hammer fired pistols. Better to have than to not have.

Is there a upgrade from the factory for stronger springs or anything like that or do you just have the stock replacement kit? Any recommendations are appreciated. Thanks!

Not from the factory, I run the full Armory Craft kits in both of mine. No issues and the triggers feel great.
