I have a Beretta 950B "Jetfire" that has been totally reliable so long as I use factory Beretta magazines. The only time I've had trouble was when I tried to use Mec-Gar magazines (which I've had very good luck with in other pistols). With factory mags, I've never had a malfunction with Winchester, Remington, Fiocchi, S&B, or Prvi Partizan ammo though admittedly all of that has been 50gr FMJ (I think hollowpoints are kind of silly in .25 Auto).
I do, however, frequently get a bit of hammer bite from the little Beretta. Not enough to draw blood but enough that any more than 50 rounds in a sitting gets a bit uncomfortable and leaves a red patch on the web of my hand.
I agree with others here that the OP's most likely issue is a disagreement between the shape of his hands and the miniscule grip of most .25's. Though not a .25, I've seen this issue myself with my father and a Walther PPK/s. While we both have large hands, mine are shaped differently than my dad's as I have narrower palms and longer fingers than he does. The particular PPK/s that he had would shift around in his hand and cause malfunctions unless he repositioned his grip with every shot, certainly not a good thing for a defensive pistol. I, however, could take the same gun with the same mags and ammo and do rapid mag dumps with no issues. After trying several different types of ammo and grips, Dad finally gave up and traded it off for a Ruger LCR.
