Is it ok to get a $2000 Luger... then shoot it often?

I've been thinking about spending $2000ish on a Luger with matching parts, excellent bore, and great blue/straw condition. I saw a few posts where others say they only shoot their "shooter" lugers. I understand how breaking a part on a "collector" luger would instantly render it as a "shooter" luger, but how likely is this? Seems like these guns were tested thoroughly for the military, and they should be very reliable, no? Are WW1 lugers not as durable as the WW2 lugers due to metallurgical reasons? I'm trying to understand how shooting even 1000-2000 rounds through it each year would be highly risky.
