Congratulations and good luck with it. I can’t even guess how many thousands of rounds I’ve put through mine and every time I shoot it it has been flawless. It’s one of the best pistols I have.
I like 124 grain in mine too, doesn’t seem to matter what you shovel in it still goes bang. For the range I use reloads but Hornady Critical Duty for defensive carry. It really is a great little gun and it’s bigger brother the Q takes over where the S takes off! I honestly don’t know if I could justify treatingI've enjoyed mine.
Everyone is different, but I've found 124 grn Fiocchi JHP's most accurate.
I added Tractiongrips and really notice a difference.
