I believe if you run 100-150 rounds thru any handgun with no hiccups at all you can consider it reliable. 500 is too extreme IMO. As far as accuracy goes, reliability is a whole lot more important than accuracy in a carry gun where it has been proven most shootouts occur withing 10 ft.

Most people could not shoot 200 rounds straight, witj one of these sub compacts that are so popular today

I have a Smith 686, and with cast bullets ,I can go 400 rounds or so without a cleaning if I am using Universal Clays.It is usually the bullet that mucks up a gun with that many rounds though

If God wanted you to walk and carry things on your back, He would not have invented stirrups and pack saddles
