I've had jamming issues with all ammo. We stopped using it because either we just had bad batches, and that day we had several officers with jamming problems. If it's a weight issue I don't see much of a difference with aluminum vs. brass casings. if there is a difference I'm sure it's barley noticeable if noticeable if at all. If your carrying a weapon, and the reason is for protection, I personally would use quality ammo. Speer isn't a bad ammo manufacture. I use their Gold Dot in my Glock and duty weapon. I also use Ranger SKT's.
