My CM9 eats these like candy. Never had a stoppage on these choices in my gun. Probably 500 rounds of the Blazer so far and about 50 of the 147 grain HST's.
I've found that the heavier bullet will print a bit higher than the lighter ones, like maybe 3 inches. This is at about a 7-10 yard range with my 9mm pistols. Have you found that to be the case with your pistol? Is it a P/CM9?

For that reason I tend to practice and carry the same bullet weight. But it might be my technique shooting.....<g>
