      1. Anyone 21 and over can buy this you do not need a permit/license. Some people are hating on it saying why should a 9mm ever look like this but that’s the beauty of it. If this was an AR not considered a pistol you would need a licence because of the length of the gun being too small. I love it and wigh a scope on it I shoot bulls all day at 30 yards.

    1. What use is this firearm designed for? Self-defense in close quarters against 30 intruders? Close quarters combat generally? With a 3.5” barrel it can’t be accurate past about 20 yards, can it?

      1. Barrel length has nothing to do with accuracy and everything to do with velocity. Barrel twist, fitment tolerances and thickness of the barrel effect accuracy. The reason why most pistols arent as accurate is A. Because its hand held without a stock and B. Because the tilting Barrel mechanism requires tight tolerances in order to move the exact same way every time, tolerances only found in match grade barrels that are hand fitted.

    2. Well the Sig MPX or the CZ evo 3 S2 or the s1 with the mini cinversion. Wonder if Franklin Armory makes a binary trigger for each. Adding a nice compact suppressor for the final touch would hit the spot.

    3. That is one ugly weapon. Why would any 9mm need to look like that?
      Has Sig embraced the ‘fantasy’ weapon genre? What next? A unicorn horn bayonet mount?

      1. I dunno man, looks more like Sig is the the new HK.. this doesn’t look much different then an MP5-K, except ya know, it is probably much easier to use, has bolt hold open on last round, an a bolt release that isn’t bass ackward.

    4. If looks could kill and could determine a fine weapon , your right on ,but sig has and still does that anyway since the P-226
