The Modernized Pasta Information aka Beretta

what does the maintenance look like on these when actually used?

For the love of all things holy, don't ask the .mil...but there are round counts for the springs and locking block.

I think a modern locking block is supposed to be replaced every 30K or so.

I recall the trigger spring is a 5K affair and it seems logical to also change the recoil spring while you're at it...
