.50 AE is more practical...

The reality is that you need to find a caliber you can train regularly enough with to become proficient with. Bigger calibers generally have more recoil (and effective range, but that's given the data on the close-range nature of defensive shootings that's not likely to be very useful) and if you can't train enough with them they're not much use to you. This is likely the reason why the FBI went back to 9x19mm despite experimenting first with 10mm and then .40 S&W.

Have you tried using moon clips for revolvers? They have the potential to be even faster than speedloaders, and also make retaining spent brass cases very easy.

I've heard that fully-loaded 10mm out of purpose-built 10mm handguns has less felt recoil than fully-loaded .40 S&W, despite the fact that .40 S&W was a downloaded version of the 10mm. Is it because 10mm handguns are built larger and heavier than .40 S&W ones, since the latter were intended to be very similar in size to 9x19mm handguns?

6-8 little poles into 6-8 little holes on the wrong side of the gun, don't think it'll fly

This'n here

.40 exists because someone took a look at the 10mm load the FBI was using and figured out they could get the same performance out of a shorter round, allowing for a smaller gun with a higher capacity. Honestly the 1006/1076/whatever they issued was kind of wasted on the piddly pop 10mm load they were using

I'll give you $5 and half a Coke for it

Oh lord the Caliber War has arrived here at imfdb. Albeit in a very civilized way. Here's what I go with.

I carry the Federal 124 grain +P HST jacketed hollow point in my Glock 19. My backup is a Smith & Wesson Model 49 Bodyguard. I carry 125 grain +P jacketed hollow points in it. I like the 45 acp and the 357 magnum, but for everyday I go with the 9mm and 38 Special. Bullet engineering has come a long ways since the FBI-Miami Shooting in 1986. I like the 9mm. I shoot it well. Also I don't have big hands and I find the Glock 19 Gen 4 to be comfortable and easy to handle. The 9mm doesn't beat up a pistol like more high powered loads do (40 S&W) and it's more affordable.

I am one of a handful of officers that carry the Glock 19. The majority carry the Glock 21 (45acp). Most of our detectives carry the Glock 30, but a few carry the Glock 19.

In the past fifteen years (since I've been with my agency) we've had three officer involved shootings. One suspect was put down with a single 45 to his heart. Another one took several 5.56 mm rounds - fired by SWAT when he pointed a gun at them. The last one was shot by an off duty officer who was carrying a S&W Model 640 in 38 Special. He hit the suspect in the shin. The hollow point performed perfectly and shattered the suspect's shin bone.:eek: The suspect promptly fell to the ground, dropped his gun (a POS Raven 25 caliber pistol) screamed in agony and gave up. He is still in prison and the officer is still working with us.

In all three cases the bullets did what they were supposed to do regardless of the caliber. They ended the threat. The loss of life is secondary (not desired) in law enforcement . Despite what all the screeching and the "protesters" would have you believe over the past year we don't want to kill people. No I haven't been in a shooting and I hope I never am involved in a shooting. I have nine more years to go before I can retire. No shootings. Please.

What do you mean? Of course moon clips for revolvers have to be inserted into the rear of the cylinder, just like speedloaders.

In this respect the 10mm was ahead of its time, as the technology and techniques to make handguns strong enough to handle it over a long lifetime of use weren't available then. Perhaps the FBI could have tried the Glock 20 instead of switching back to 9mm (their SWAT teams are still using the 10mm version of the MP5). .40 S&W guns have had a reputation for self-destructing, but that hasn't been heard of in purpose-built 10mm guns (at least not as often). The Glock 20 can be converted to fire .40 S&W (for cheaper training ammo) and .357 SIG with nothing more than a barrel change as well.

But in any case, what exactly is AdAstra2009 willing to try? There's lots to try out there, and given the "ammo panics" prices of widely-used calibers aren't guaranteed to stay affordable.

Yes. that's it. The 40 caliber pistols mostly start out as 9mm models which is part of the problem. It is my understanding that the S&W 3rd Generation 40 (4000 models) caliber pistols were built around the 40 S&W which is why they had a better track record. However I have never owned one of the 40 caliber S&W autos so I'm going off what I've read on the S&W forums.

I am left handed

The cylinder on all but the Charter Arms Southpaw open out the left side of the gun, meaning I am meant to reload using the hand with which I am currently gripping the revolver

The cylinder release is on the left side of the gun, the opposite side of where my thumb would be situated

As someone who is left handed, this configuration is functionally useless to me unless I have 20 seconds or so to reload

Well, that just gives more reason for those using purpose-built .40 S&Ws to go and try 10mm handguns. Conversion barrels to .40 S&W are usually available for those.

Kind of makes you wish the MP-412 REX hadn't been cancelled, doesn't it? Top-break revolvers like the REX are ambidextrous, after all. Have you tried moving the revolver over to your right hand so you can push the cylinder release, then putting the revolver back in your left hand after you've finished reloading?
