The Derringer is a well built fire arm built by Bond Arms and would recommend it to anyone. I shot it the other day with the 410 bird shot and the 2 1/2 in. 410 buck shot and now I know why gamblers used it at the card table and not at long range. I stepped off 20 ft. and fired at a half silhouette. With the bird shot, I got a few in the target. With the buck shot-nothing. I know I’m not that bad with a hand gun, so my conclusion is that you need to make sure the subject, if you need to use it, isn’t more than 10 ft. away. I haven’t tried the 45 cal. in it yet but I expect the same results. Like I said, it’s a beautiful built gun and would recommend it to anyone but remember it is a short range pistol- very short range.
