Armscor .22 TCM
Yep, that funky necked down .22 there. Like the 5.7, the idea is propelling small projectiles at high speeds-- In this case, 2100fps with some loads hitting Mach 2. The low recoil round purportedly creates comparatively large wound cavities while expending it's energy quickly on the target, with supposed bonuses against body armor. I've seen water jug tests where a normal .22lr will penetrate deeper, but without as much destructive force going in. So what does that have to do with 1911s?
Glad you asked.
Meet the RIA/Armscor .22tcm, a full-sized 1911 with 17 round capacity. Personally, I think they did a smart thing here, something that FN kinda failed at: RIA picked a well respected platform to field their fledgling ammunition instead of pushing it through a more exotic and expensive firearm. As a self defense round, I'm half tempted. Even better, the 1911 easily converts to 9mm should you feel the need to change it up... Or this .22tcm stuff becomes harder/more expensive to come by. That said, i don't think RIA is going anywhere anytime soon.
And last I checked, a .22lr doesn't do this to a watermelon from a handgun--

That made me choke for a few seconds. a DS is "a lot" thicker than a single stack. Like comparing a 1x2 to a 2x4 or a Mop handle to an Axe handle.
