Is that an AR15 in your pocket? Or...

We have to emphasize however, that touching off the .22 TCM 9R in the confined space of one’s house can be a nerve-wracking experience. To say that it is loud would be a tremendous understatement. Moreover, a shot in the dark could temporarily impair one’s natural night vision—which would not be good if one is engaged in a fight for survival in low-light.

I like the idea, but this would keep it away from home defense duty for me:

I was not thinking home defense for night work. I was thinking more for a day time application and switch out the slides so you are back to the 9mm at night... There are less chances that a 22TCMR9 will penetrate walls during the day when more people are roaming about.

Night time is different since less people/children are up and out. So a 9mm is a better choice then.

Unimpressed. I can get 2000 fps with a 110 gr JHP out of an m1 carbine. In my opinion that's a better home defense weapon. Light, easy to manipulate, lo recoil and devastating.
I would rather keep the glock a 9mm.

Can you carry that carbine in a holster on your side, with 17 rounds in the grip?
And will that 2000 FPS 9mm stop when it hits a wall?

Take one 5.56 casing...
Cut it short...
Redo the neck to accept a .224...
Shorten the bullet to fit the rounds into a Glock 17 magazine...
Mill slide and install barrel and spring...

One RIA 22TCM9R at your service... 2000 feet per second...

practically speaking, aside from the fun of an "adult" shop project, why are we trying to reach 2000fps? whats the point? and as far as punching through walls- don't miss...

I can carry 16rds which depending on the ammo runs avg 1100-1300fps...and I MAY want to punch through walls- again theres no definite standard issues...I hd lived in a townhouse that had cinder block firewalls between each unit...my current house your point of entry runs parallel to my bed (and where I live, if theres someone in your house at night it aint an accident...) so I MAY want to put rounds through that wall...and before anyone speaks of the poor ole innocents- THERE ARE NONE, going that direction there is over a mile of trees, and the other direction a big dirt berm...

just wondering on the "why" behind the question from a practical sense

....ps I bought one of the underground missile silos and converted it...

no, not really, but I do live in the mountains...our shitty road is our security plan- no one f*cks w/ us or robs us cuz they can't haul ass out of here...and they don't actually know if someone IS home or IF someone ELSE is watching your property...and we all got guns...many guns...my guess- minimum of 4 per household, and some 10-12

Isn't this why the 5.7 X 28 round came about?
