I ran a Sig P228 9mm Luger for over 6,000 rounds before cleaning it and it still did not fail to feed, fail to extract, or stovepipe, nada, nothing, ding. Ammunition was mostly Winchester White box, some CCI Blazer and maybe a few mags of Federal American Eagle.
I wouldn't rec' it, but just saying, that some guns will run and some wont without a regular field stip cleaning and lubrication.
If it's an 1911, you'll have to clean it once every two mags..............
