Hi,
Don't recall ever seeing any failures to fire w/ CCI primers in handguns that were left at factory spec. Putting in lighter springs has been associated w/ some failures: the CCI cup tends to be a bit harder than most, and some smiths have recommended Federals (softest cup of the major mfrs) for modified guns (my old gunsmith boss among them.)
If you're gun's factory stock, neither damaged nor overly worn, properly cleaned and lubed, I'd look carefully at your loading practices for the "problems" others have already noted. Yes, it IS possible you got some "bad" ones, though I'd expect that more of current lots, where all the production is under stress to keep up w/ demand, than older ones. Still, it happens...
