No way. I carry for 2 reasons. One to protect myself and my loved ones, and two to protect our rights by educating the public. That thing is nothing but a hindrance to both counts.
First let's get the P.R. issue out of the way. If you are carrying to educate the public, that is only going to drive the neutral folks away. Hell, I don't understand care for it myself (but I do support your right to carry as long as it is legal where you are)
Second, as far as tactics go, that thing is worthless. The benefit you get from it being quiet is drastically reduced but the fact that you now have no sights and no balance. In addition to that, have you ever seen what happens when you shoot through a mis-aligned silencer? It's not pretty. And all it takes is you bumping it and sitting on it wrong just once. Then you have the whole issue of giving you attacker a handle on your weapon. Someone earlier mentions that at that range you should pull a knife, but I generally don't carry fighting knives on my person. There's just too many drawbacks to using it for it to be a viable option for OC.
Just my humble opinion. But it is based in real world experience.
