If a range toy breaks, no big deal.
If a carry pistol breaks when it is needed, that is very different.
Absolutely and both can happen at any given time, any given place regardless of round count.
I like to compare it to, you arrive home park your vehicle and all is good. You get in the vehicle to leave and click, click, dead battery. Never know when it will happen.
After a break in of 2-300 rounds I expect any gun when used to go bang when asked to do so.
