I owned a Taurus PT92 years ago and it ran 100% with everything I fed it, including JHPs. It's based on the Beretta 92 design, which is reliable with any reasonable ammo.
I'd be concerned about overpenetration with 9mm ball, which digs pretty deeply in people, and frequently exits.
The easy way to answer the reliability question is to buy 200 rounds of JHPs and shoot them. If you have no malfunctions - and I'd bet you don't - there's your answer. I understand that modern premium loads are expensive, but even the relatively affordable Winchester White Box JHPs are better than 9mm FMJ for defense.
