Actually sig Sauer has launched a lawsuit against Springfield armory for ripping off their magazine design.
Next up is it surprise you but a smaller barrel does not equate to poor accuracy. One time I shot a little television at 100 yards on the third shot with a 3.3 inch barrel.
Next up your grip is extremely important with a small pistol this size because your left hand is squeezing the bottom fingers against the frame. In my case that would be middle and ring finger. Having a two hand grip is pretty much required.
And yes you hit the nail on the head the second you start getting lighter than a certain amount then The recoil starts getting way snappier.
Which sometimes can make good morning horrible shooting gun.
Yeah, the gun isn't necessarily made less accurate with a shorter barrel. I've seen people ring coffee cans at 100 yards with every round from an officer's model 1911 clone. But the shorter sight radius makes it harder to use that accuracy potential without practice, and I need practice. And I need a 6 o'clock hold for a sight picture.
And I think lawsuits over IP are pathetic. Make a better product, don't try to hire better lawyers. Plus, I don't see what's supposed to be patentable about the mag in the first place.
