Do you really think everyone is gonna get 48lb triple recoil spring assembly springs, NY-1 triggers, two magazine springs in parallel (parallel, say what?), etc.. and overload their 9mm so as to make the .357 Sig obsolete?
And would that trick even work in a SIG, or S&W, or H&K, or any other 9mm?
I mean why not just get a Glock 10mm and put a 9x25 Dillon barrel and not all the special effort, effort that apparently makes it difficult for even you to operate the gun.
