Ive run a couple hundred rounds already and it had one failure to feed and that was because I didnt have the clip locked in all the way.
A couple hundred rounds isn't a very good test. For some reason, the Interwebs believe that 200 rounds is some magical number that means you have a great gun. When you get to 2k, let me know how flawless it's been. I have around 5k rounds through my G19 and have yet to have a single malfunction, with the exception of the stovepipe that I caused by limpwristing on purpose (and even then, it took 10 rounds for it to actually malfunction.
In the end, if you're happy with what you got, then that's great. But "a couple hundred rounds" is nothing. I'll sometimes shoot that in a session at the range.
