Don't just buy off some article.
I just like the way some pistols point for me, and not so much on others... (Just grab the gun, look at your target, and point.. then sight up and see if the barrel is tilted down, up or whatever.. And that's where your going to shoot most likely in a stress situation... Everyone's different, so try some guns, and see if I'm right.. )
I shoot low with Glock's and the XD's..
I shoot right on with my PT92, and the PT111 feels much like my larger frame auto, so I'm comfortable with it.
I've told this story before, but it's relevant to your choice.
Friend of mine was a MP in the 70's.
He came up on a guy raping a girl on base.
He pulled his 1911, and yelled for the guy to stop.
Guy comes up off the girl with a K-bar knife in his hand.
My friend shoots they guy.
He shot to kill him, center of mass, but hit him in the leg, below the knee.
Why? This was a trained MP. Someone who's a marksman with both a pistol and rifle. Why did he miss?
Stress and pointing. His natural point on that pistol is to shoot low. Give him another second to line up, and he'd have put the round anywhere he wanted, but under stress, under split second thinking, he shot the guy in the lower leg... (They had to amputate it BTW, and the military has no mercy for rapists...)
