Wilson combat specifically says NOT to disassemble/clean their new pistol until shooting 300-500 rounds. It's probably an exception to the general rule, but they have their reasons for that position. I'm a lot less concerned when testing a revolver, although a malf (when a gun doesn't work it is a malfunction - "jam" goes on toast) in a revolver is a much harder problem to resolve than in an autopistol; most of those are solved with an immediate action drill.
The last autopistol I tested was an issued G21. It got about 200 rounds of ball and 300 rounds of duty ammo before qualification, partly for familiarization with the different feel and new holster, partly because of the need to test. That's minimal. It also got a couple hundred rounds around the qualification course and related events.
I have an early Wilson KZ9. When they first came out, the mags were a soup sandwich. I helped the then shop manager with testing and evaluation of the mags and their evolving configuration. When they were confident it was right and I got it back, I ran over 800 rounds of mixed ammo, mostly good carry ammo, without cleaning, and with no malfunctions. I still have not had a malfunction since. I do not use cheap ammo; most of my practice ammo is Black Hills, and serious ammo is BH, Winchester, or Speer Gold Dot.
My Hilton Yam built 1911 has had a couple thousand rounds through it since I have owned it. 4 malfs were related to using +p ammo for which it was not tuned - answer: don't do that. I think I had 1, maybe 2 others, using the cheap department training ammo. Over 1000 rounds of duty ammo and a decent amount of BH ball - no malfs.
