congrat's - I love mine, it's a phenomenal gun. If you don't like, just send it to me.
For practice, I usually shoot Fiocchi or Blazer Brass 115 grain, it loves both, no prob's.
I've used Gold Dot's, no problem (one self-inflicted thumb-on-slide jam, I now lock thumbs vs. thumbs up). BTW, I've used both Speer and Georgia Arms loaded Gold Dots, regular, +p, +p+, 115 and 124 grain, all fine.
I currently use Ranger SXT +P+ 127 grain, and occasionally Ranger Bonded +P 124 grain, also no problems. Rangers seem to feed the best of all the HP, are dirt cheap for carry ammo ($15-$21 for 50) and NO FLASH!!!!
The only thing mine doesn't like is Federal Hydroshocks... I bought a box because I miscounted a box of Ranger and ran out at the range. TWO jams in one box... one slammed the bullet back into the case significantly and jammed before firing, I still have that one sitting around somewhere
Fortunately I hate Hydroshocks because of the flash, so I wouldn't carry them normally anyway.
I hope you enjoy your new acquisition!
