I'm just back from the range where I ran 25 rounds of American Eagle 124 gr. FMJ and 25 rounds of Fiocchi 124 gr. JHP through my new Stealth.  The A.E. went through without a hitch.  But after a 10 minute cool down period, the Fiocchi had 1 FTE and 1 FTF.  Although the Fiocchi works fine with my Glocks, obviously they aren't the right HD or PD choice for the R9.
I've seen a number of recommendations in this forum for Speer Gold Dot HP, so I browsed various ammo pages and found Gold Dot 115 gr. HP and Gold Dot 124 gr. HP (neither are +P).  FWIW, these loads are both $24.95/50 on Ammo To Go.  Before ordering one of the other, I thought it would be a good idea if I asked here which should be the most reliable in my R9, the 115 gr. or the 124 gr.?
Thanks in advance . . .
