I have never shot a SIG but, it looks to me that the bore axis is pretty high above the grip. After watching guys shood IDPA with them,they look like they recoil quite a bit. Granted, most of the ones I've see were in .40 but even still, compared to say, a G35, the SIG looks like a handfull. Do you find this to be an issue?
I've never taken a close look at one, but I'm pretty sure the bore axes of the P226 and the pistol you bear the namesake of are virtually identical. It's a non issue for me. Watch some of my videos and you'll see how mild the muzzle flip is with a proper grip and a modicum of grip strength.
I run a 14lb Wolff recoil spring for ammo around 135pf. Works great.
I was not trying to promote Glocks even though I compete with one right now. I started with a 92FS. If it had a replacable front sight and was a G model, I'd still be shooting it. I hit the saftey on or, forgot to turn it off too many times. Getting my hands on an Elite II G was just not practical. I think Ben has most of them at this point. There is nothing like shooting a metal gun in my opinion.
