look up.!!

Glockman 22 did a good job but left out two very important and useful loadings.

9mm +p
such as loaded by Corbon Pow'rBall
excellent 100 grain bullet at 1450 fps and 467 ftlbs of energy.

9mm +P+
such as loaded by Buffalo Bore (available at Cabela's)
They load the proven Speer 115 Gold Dot bullet to 1400 fps and 500 ftlbs of energy. This is 200 fps faster than the Speer civilian loading and yeilds a significant 36 % increase in energy.

All modern 9mm pistols can handle these but you can mostly practice with the cheap mild 9mm ammo.

500 ftlbs in a high capicity pistol is why this Glockman carrys a G19

So there are the numbers make your choice.

I never thought i would say this but,thanks glockman...i have chosen ,i own a glock 22

I follow the momentum theory, which means that a round is judged by its momentum (mass * velocity) and not its energy (0.5*mass*velocity^2). So the original chart again.

9MM 1100fps 336ft-lbs = .61 lb-ft/sec

357SIG 1350fps 502ft/lbs = .74 lb-ft/sec

40S&W 1200fps 496 ft/lbs = .83 lb-ft/sec

10MM 1290fps 649ft/lbs = 1.01 lb-ft/sec

45ACP 900fps 412ft/lbs = .92 lb-ft/sec

45GAP 950fps 401ft/lbs = .84 lb-ft/sec

That being said all of the above calibers are well suited for personal defense.

all of that information is fine and dandy....
however, one of the major drawbacks of the .40 S&W round is the chamber pressure. its WAY up there compared to the 9mm and the .45 ACP. In fact, its one of the reasons Gaston Glock came up with the .45 GAP - to solve the HUGE pressure differences of the 9mm, 45 ACP and the .40 S&W.
There are way more documented chamber failures with the .40 S&W for a reason. Its a great round, but to my recollection its almost 10K psi more than the 45 or the 9mm.

I don't think the statements in bold are true. The .40 and 9mm para run at about the same pressures.

From what I've read Glock's main reason for the 45 GAP was to have guns with a smaller grip available in 45 caliber. The GAP brass is indeed stronger than 45 ACP brass, but it does run pressures around where 45 ACP +p rounds are.

this is load advice based on actual shootings in each caliber

eh.
it appears I have something mixed up in my memory.
thanks.

If you compare a "high performance" 40SW to a " high performance" 45ACP in the same weight bullets, 4" barrels, you will find that the 40 SW has greater FPE ( foot pounds energy). But this is not the only consideration- type of bullet- ball,jacketed HP, frangible each have there uses and 1 is not best for ALL defensive situations. 9mm-40SW-10mm-45ACP-45GAP all can and will stop an attack, unfortunately all will fail at times. Handgun calibers are there to be with you when you need it, instead of the shotgun in the car. Therefore-practice, practice,practice. ONLY HITS COUNT!!!!
