I have the Advantage Arms kit for the G17. It is picky on ammo in my limited experience. It seems to like CCI Mini Mag 40 gr round nose the best. I just fired 100 yesterday with one FTE.
Also fired about 40 CCI Standard velocity with no problems which is odd because you are only supposed to use high velocity.
It did not like Winchester SuperX 40gr, plated high velocity round nose. Constant FTF, FTE, stove pipes and was a jamb-o-matic.
Oddly enough I bought some Winchester SuperX 37gr. high velocity hollow points and they seemed to work fairly well although I only fired about 30 rounds.
I wish I could say I fired 700+ rounds with no malfunction but this is not the case. I will give the Wildcats a try.
