Yep, they are a dedicated single action. Cocking the hammer engages the trigger. I have owned several of the late 1800 S&Ws and a C&B Pocket Remington with the spur trigger, and, I kind of like em. With the spur trigger, the single action kind of negates the purpose of a trigger guard. It slims the profile and makes for and easier concealment.
I've looked at the NAA minis for years, and although the concept always grabbed me, the functionality didn't. The traditional NAA birds head grip was too small for my hands and just didn't feel right. The Black Widow is another story. The grip is great, the two inch flat topped barrel with enhanced sights bring this small gun into another category.
The fit, finish, and quality of this little gun are more than could be expected for the price. The only down side that I see is that reloading will be a little slow - but when SHTF, are you really going to have time for a reload on a "close quarters"
handgun??? Maybe, maybe not.
Shot placement would definitely be critical with a .22, but, then I have never been one to hold to a guaranteed one shot stop with any caliber. At 3-5 yards its hard to miss.
Since we are on the .22. I grew up in the rural South. My first rifle and handgun were both .22s. Every farmer I knew had either a .22 rifle or handgun in their pick-up. We shot every thing that needed shooting with them. Rabbits and squirrels were a given, so were coyotes and feral dogs that bothered livestock. At hog killing time, they put more than their share of bacon, sausage, and ham, up for the winter. The .22 has been a staple for most of my life. Some folks say they are unreliable? I've had just about as many bad primers as I have had bad rim fires. Internet legends are hard too die, and a lot of folks spend more time on the keyboard than they do on the range or in the field. Personally, I'm just as comfortable with a .22 as any other caliber within their design. Now, having said that, if I knew I was going to be in a gunfight, I bring my big bore rifle.
Not sure how the Black Widow is going to perform. I will be posting a range report and review as soon as I get it to the range. But, so far I am impressed with what I have seen, both with the quality build of the gun and other reviews.
