    What do you guys prefer? What do you use on the range, and what do you carry with, and why?

    I've only practiced with 115 through my G19, and I've had good results.

    I just ordered some 124 to practice with; what differences can I expect from the 115 I've been using?

    What about 147?

    Thanks in advance, my fellow SD shooters!

    Range the cheapest brass I can find, usually 115gr.

    Really depends on the loads. Generally the heavier bullets to me feel like more push and less muzzle flip. However if they load that 124 to similar velocities as 115 you can expect more flip and felt push.

    But generally for standard loads felt recoil should be slightly decreased as you move up in bullet weight. Less weight, more powder, more velocity and energy = more felt

    For carry/hd I like Underwood ammo, with speer gold dots. 124gr or 147gr. Speer gold dots are proven performers and underwood ammo loads them hot. Great expansion and penetration.

    The 124 +p+ expands slightly less but you get a bit more penetration. That is just for that particular load generally 147 will penetrate deeper and have less expansion. Something to do with how hot underwoods +p+ is the reason that is reversed, mass plus velocity, bullet construction and whatnot.
