Questions like this always arouse my curiosity.
Did you ask the salesman how many miles your truck will run before it falls apart ?
Did you ask thr real estete agent how long before your new house crumbles in to a pile of toothpicks ?
Do YOU actually do ANY shooting atall, or is this just an exercise in gumbumping to fill time ?
ME....I've spent sixtyfive years trying to see if you can wear out ANY pistol. The only one to fall apart was a Walther P22, the biggest POS gun I ever beheld and my wife trashed it in one year with less that 7M rounds of ammunition. It's replacement , a NEW Walther PP22, has 10M [10,374 actually ...] rounds through it now and still looks absolute brand new.
SO....WHY do you not quit asking and go find out yourself. I already know the answer.
And so it goes...
