Clip question

[skeet]

In the late 80's I bought a Walther P-38 that a friend had brought back from WWII. It had an extra mag that was loaded in the holster pouch for the gun. It had been loaded since at least 1945. After I acquired it I shot those rounds out of the gun and the gun ..mags and ammo all functioned just fine. The gun was not very accurate(or maybe it was me) but the mag is still being used by the fellow I sold it to. He shoots it occasionally down in Florida. He uses it for a house gun.
