Nunca he escuchado de una Sig220 9mm, Puedes abundar al respecto?
IMO, there is something to be said about being "the best" at being a pocket pistol, managing to stay under 23 ounces but still fire a major caliber like the 9mm, having a snag-free design and usable sights.
I've owned 3 of them, am a big fan of P-series pistols, but the 225 is bigger than a single stack 9mm needs to be. For that size/weight you can carry something with a lot more capacity, if desired. I have a S&W 3953, would never carry a 225 over it.
That new Walther looks very interesting. Walther's version of the HK P7...
If tiny is required, then one should look to the Rohrbaugh. It's thin, light, reliable and certainly small enough to conceal in just about any circumstance. The one drawback; like the HK P7, not a gun you put hundreds of rounds through in a short period of time.
I'm buying my wife one so I can keep mine!if im caught carrying a single stack 9mm it going to be a Shield, and my wife is going to want to know what im doing with her gun
