Seems most people recommend carrying 147gr hollowpoints for 9mm... so why isn't 147gr the most commonly available version?
I guess people could say cost... but doesn't the 147gr have a big difference in recoil compared to the 115gr?
Just asking since I'm signed up for a handgun course in another 2 months... and need to buy up 1500-2000 rounds of 9mm soon. Haven't decided what gr 9mm to get!

I'll make it easy for you...
For your course, buy bulk from SGAMMO.COM. Get either the Federal Lawman 124gr or the Blazer Brass 124gr. You could go 115 grain, also, if you like, but I prefer 124's myself.

As for why people like the HST's in 147 grain, it's because they consistently show monster expansion, up to around .75 inch max, and adequate penetration of 12 to 14 inches in gel. They're just the popular thing these days, mostly because of Youtube video tests. I'm looking for more penetration when I buy. I carry the HST 147's, but have been looking into Hornady Critical Duty 135gr. They don't expand as much, but they penetrate deeply, and expand enough.
When it comes down to it, most any top load in 124 grain, and a select few in 147 grain, are going to perform, if you do your part. Choose what works best in your gun, and feels best to you.
