I have 3 kinds of ammo to choose from for carry in my SR9c. Barring the 'which one cycles best in your gun and how accurate' responses,they all shoot well and are accurate in it. I have rangerT124+P, gold dot 124, and powerball 100+p. I love the rangerT when it expands and the gold dots are great as well. But the powerball goes like 1450fps with around 470ftlb. Also It doesnt seem like it should over penetrate puting those standing behind the BG at risk. Ive shot water jugs with all of them and the powerball gives an awesome hit and never goes thru the second jug. What do you guys think?
