Got a new gun in yesterday, a Rock Island/Armcorp double stack 1911 in 9mm with a extra barrel for some new round called the 9mmTCM. A 9mm necked down to .22 cal. All these new rounds usually just don't go nowhere, with the exception of the .40 when it was brought out, and the .17HMR, the only two I can think of that has really took off. The .204 Ruger to a far lesser degree. I would say that a .22 cal bullet from a 9mm case would be a zippy little round! Probably like a 5.7. Time will tell.

I think that this one falls under the "Why" category. A super zippy .22 makes a certain amount of sense in a rifle. In a 1911 configuration? Why? The 5.7 was a specialty round to deal with body armor and provide low recoil and high capacity. Even here, the pistol was an after thought to go with the P90. I'm not sure the world needs another version. The standard 9mm barrel as an add on makes a certain amount of sense except for two problems. One, the 9mm is going to be exponentially cheaper to shoot, and its what you'd probably choose for SD anyway, so why bother? Just sayin'.
FQ13

I have to agree with FQ on this.
It is probably pure death on squirrels and other small varmints in the same gun you carry for SD, but with all the .22 conversions available that is not an issue.
I don't see this round ever being more than a curiosity. Hang on to that barrel though as it may add to the eventual resale value of your pistol.
As to "Why ?" that I can answer.
One or more people interested in "Wildcat" cartridges were sitting around, (Possible involvement of adult beverages)
Discussing how to neck down a 20 MM casing to .17 cal when some one observed, "there is to much excess material at the neck, but I bet we could get a 9mm case to take a .22" He then went over to his work bench and said, "Hold my beer and watch this" ;D
The short version would be "Because they could" ;D

Did someone call 911 down in Fla? TomB agreed with FQ13? That must have started a minor earth quake at least! WOW!

I'm rechecking my heart meds as you post ;D

With a solid bullet it should have a ridiculous amount of penetration and hollowpoints would surely expand without any problem. The energy of a fairly hot .45 with 1/4 of the recoil should make it fun to shoot and effective too. What's the down side?

None of us have said it's a bad round, just that it will be a commercial flop.

Does sound a lot like a 17 Mach2. Anyone remember that?

I remember it was introduced, but they had some sort of problem with the performance and it was recalled and not to my knowledge ever returned to the market.

The .17M2 wasn't safe to use in semi-autos. That's the only thing I know that was wrong with it. It deserved to die.

The 17 HMR is based on the 22 magnum case, the M2 was based on the 22 LR case, apparently while rechambered magnums could handle the pressure it did not work that way with the 22 LR actions.
http://en.wikipedia.org/wiki/.17_HM2
Since the .17 HM2 is based on the .22 Long Rifle, converting most firearms chambered in .22 Long Rifle to .17 HM2 requires only a barrel change. The higher pressures makes conversion of semi-automatic firearms more difficult, as virtually all are blowback designs that are sensitive to pressure changes. Kits for the Ruger 10/22 and AR-15 platform have appeared, and they replace the factory bolt or bolt handle with a heavier one to increase the bolt mass and compensate for the higher pressure. Since the .22 Long Rifle is arguably the most popular cartridge in the world, the .17 HM2 has a large pool of potential firearms that could chamber it, and a huge infrastructure to manufacture the rimfire case it is based on.
