[QUOTE="GlockPride, post: 3157679, member: 12153"] 5.56 will carry much more energy than 9x19. Could be looking at 825+ ft lbs assuming 55gr projectile at 2600 FPS. Numbers taken from BBTI and Federal’s ballistic calculator. I think max for 9x19 is going to be somewhere around 425 ft lbs or so depending on +p, barrel length, ammo mfg, etc. HST @ 124gr @ 1150 FPS is only 364 ft lbs. However, 5.56 has much more blast and percussion. Depends on what you’re doing, your layout, range distances, etc. I like AR platform in 10.5”, I have two of them. But, you have to decide what trade-offs you’re willing to accept. [/QUOTE]
