Tough room. I love my SBR'd Kahr Thompson, and I'll task anyone who thinks it's "irrelevant' to stand down range at relative CQB ranges and let me show them how irrelevant it is. Dead is dead. I wouldn't want anyone shooting at me with one.
Having said all that, I think they are making a big mistake. They'd have to halve the weight, halve the price, replace the sights, add a real bolt hold-open, add rails, and add a side-folding, or wire stock (ala the M3 Greasegun)...and it would have to be SBR'd without the dorky 16" barrel.
Do all that and you'd have a handy little .45 devastator. Of course, do all that and it wouldn't be a Thompson. It would still suffer from an antiquated and difficult to change magazine design, and Kahr's dubious reliability (mine works, but I seem to be the only one), bad customer service, and the fact no one on this world could make it at the price it would need to be sold at. Which brings us right around back where we started. And that's without even mentioning the horrible bullet drop of the .45ACP at anything even approaching 100 yards.
If they want to play tactical, they should come up with something that's not based on a WW1 design.
