In answer to your question, and this is just one man's opinion....Kahr's .380 is a handful to shoot, requiring seemingly constant hand repositioning to maintain a secure hold, not to mention very overpriced. Sig, I'll admit is an excellent weapon, and quality wise, has everyone beat, hands down.....However I believe that "pocket rockets should be DAO for safety and speed, and as for Ruger...nice try at copying the Kel-Tec, but they have failed MISERABLY at quality since Bill died, and Corporate took over. All I'm saying, is that, feature for feature, S&W nailed it in ergonomics, design, controllability, reliability, shootability, accuracy, safety, material quality and fit & finish, and installed factory features found only on expensive full sized guns, in a one-time-purchase package ( no accessories needed)and all at a price which is well within reach of the average working Joe. What was wrong with the others------none of them has accomplished all this in one affordable package yet, until S&W did it. Good weapons have good features. Excellent weapons have everything you could ever want on them at an affordable price. And that to me is where the others fell short......not trying to be a gun snob, just a hyper-pragmatic old Scottish curmudgeon who likes things simple, like the old days............... Thanks, Angus
