I had this issue with an early Gen 2 Glock 23. Every once in a while I would get a light strike on the primer and fail to fire. I had the RSA replaced with a fresh one and fired 900 rounds without cleaning the gun (it was a test) and had no issue.
Edit: I will be firing 200 rounds of the Underwood 180 grain fmj today as a matter of fact. I will let you know if there are any problems, but I doubt it was the ammo.
