I have to agree with you MadBodhi. The Sig is great little handgun. So is the Glock, Kimber, HK, Taurus, Springfield, Bren, Kahr, Kel-Tec, AA, Bersa ....and on ....and on. I know first hand, because I have owned several of most of these weapons. I can, and do, shoot them all pretty well. Maybe some better than others, but I can shoot anything I pick up, better than most people. I've had problems with some guns that I had to troubleshoot and correct. Sometimes its as simple as the wrong ammo. Afterall, a gun is just a machine and nothing is perfect.
The biggest factor for failure that I have found over the last 35 years, hundreds of guns and tens of thousands of rounds, is the shooter. I discovered at some point along the way, to stop searching for a gun that would compensate for my lack of ability and just become master of the weapon. I stopped trying to blame the firearms and searching for that "one magic gun". Instead, I just decided to take responsibility and get control. Funny thing is, they all shoot much better now. But hey, thats just me.....
