The FBI Just Settled the 9mm vs .40 vs .45 Debate

As to how long this discussion has be ongoing, Wild Bill Hickock shot a lot of people but continued to use older .36 (9mm) Colt navy percussion revolvers with paper cartridges well into the .45 using metallic casings era.

So, here's a question for the LEO's. The FBI guy brings up some great points that I've never thought of before, that being the problem with light grain projectiles and barrier penetration. Whether that barrier is a forearm (the AK 47 analogy) or heavily boned structures like shoulder joint enfilade trajectories. James asks the FBI guy that without endorsing, what type of ammo should civilians be looking to buy. The response was heavy weight, +P type ammo, the stuff branded as LEO ammo. Here's the question and the conundrum though. Whenever I look at this type of ammo, it's nickel washed brass cased, 147 grain, hollow points. Are LEO's using hollow points as duty ammo? I was of the understanding that hollow points speak to some sort of criminal intent? If so, how are cops being issued it?

I most certainly hope all LEOs are carrying HP as duty ammo.
 
Here's my collection of Criminal Intent, And some of the ones I've shot to make some man flowers.

I've known quite a few guys, including a friend of mine who was a 25 year Detroit PD veteran, and my uncle who was a 27 year LASD veteran, who were in a good position to compare, and nearly of all them greatly favored the .45 over the 9mm of the era.

It really wasn't until the 2000s when 9mm bullet technology had improved to the point where it started to perform equivalently to the other duty calibers, largely thanks to a whopping 70% of defensive handgun bullet R&D being devoted towards the caliber for the last couple of decades.

Yeah, one thing that many don't realize is just how much development went into powders and bullets post-2000 that the firearm world is a very different place.

Curiosity got the best of me once & I did shoot a couple mags of factory .40 S&W thru that S&W 1066 to see if it would work. The caveat being the shorter round is only held by the extractor to the breach face. And the case mouth does not headspace in the 10mm chamber of the barrel as it would with the longer 10mm round. Of course, it is said NOT to do this.

Anyway, it worked flawlessly & had no other issues. No fail to feed, fire, extract or eject. Accuracy was no real discernable difference from the factory 10mm ammo or reloads I'd made for it.

I tried that but I found it did fail to feed a few times. Granted I only tried from one mag. I'll try with a couple of other ones.

I believe he used it with roundball loads, which supposedly have noticeably better terminal effectiveness than non expanding cylindrical bullet loads of the same caliber and velocity.
 
Does anyone know how to get the Moon Clipper Unloader? They won't sell to Canada . And those are expensive as well.:(
