Aye. It surprised me as well. But from what I was told, the Geco is a hot load, as well as the RA9TA. Shot out of a Glock 34, that same ammo on that day was hitting about 1,350 for the Geco, and 1,320 for the RA9TA.

Id look at energy produced over velocity. Not that there would be much difference between any 9mm setups out of a 3 inch barrel. And we all know what is stated from manufacturer is in a controled enviroment, not real world to say the least.

I'd look at expansion and penetration over both.
Energy is a poor standard for determining a round's effectiveness.

The Geco FMJ load is just going to punch thru faster. The numbers mean little unless it hits bone. It's all about the bullet, not the vel or energy & shot placement of course.

Contrary to popular belief, a bullet dumping energy into a target does not do any wounding. The wounding is done my the bullet crushing tissue in it's path and if it has enough velocity (rifle) it also tears tissue via a temp cavity. This temp cavity is created by the bullet displacing tissue as it passes at high speed. The size of this temp cavity is not any larger from bullet stopping in the body than from one passing through a body. No extra damage is done buy a bullet that stays in the body. In reality more damage is done by a bullet that exits because it creates a longer crush cavity.

Two holes also allows faster bleeding. If the bullet misses vitals, you want as much add'l. bleedign as possible, two holes helps that, 4 or 6 even better.  That is what you will get w/ FMJ passing thru, which is why it wil take more than one or two rounds if you don't hit anything good or the bullets pas thru smoothly w/o tearing as in RNFMJ.

Guys, I was just wondering if anyone had actual velocities recorded because I was curious to how fast the 9mm rounds would be traveling out of the tiny "3 inch" barrel. In actuality the length the bullet travels is only 2 inches? Correct me if im wrong guys. I know thats how they measure revolver barrels...

You can expect +- 60-70 fps loss per inch lost.

Thanks for the chronos. Not too shabby. Definetely why I prefer atleast 9mm over .380 even with the shorter barrel. I use the pdx1s in 124gr +p. Great round so far.
