I'm a newbie here and to pistols in general, in fact so new that my application for a permit is still in the works. Here in New York it takes forever. Been waiting almost 8 months since I turned in all the paperwork. No pity parties please.
In any case, I've been looking at my next purchase already. I'm intrigued by the barrel swaps avail for both Glock and Sig. Been seriously looking at the 357 Sig/ 40 combination. A bit confused with some of the threads though. Is there a pistol made by Glock or Sig that will accept a barrel for 357Sig, 40 cal AND 9 mm? I know the mags are the same for the 40 and 357 and there is a no tool barrel swap, but can you change to a 9mm too? I would have to assume it would be a mag and barrel (maybe spring too) change, but can you shoot all 3 calipers with just 1 frame?
Thanks for the help.
