Well, I got to shoot the gun now. I like it a lot. A lot a lot
It seems to be more of the combat sight picture, where you cover the target with the front sight. My 226 is a 6 o'clock hold, for some reason (and my only gun like that). This M11A1 matches the sight picture of my other guns.
Gun worked 100%. Shorter sight radius does take a little more effort to hit at the longer ranges. But, I did well. Recoil isn't bad.
And, believe it or not, I didn't have that issue with my thumb hitting the slide stop on the M11A1 like I did with my 226 with the E2 grip. One of the things that pushed me to the M11A1 over the 229 with an E2 grip was as small raised area on the upper left grip. Right where your thumbs go. It seems to push your hand a little further away from the slide stop.
I suspected this might solve that issue for me at the gun store - and after shooting it, i was right. So, that was nice. The grip circumference seems to be thinner on the M11A1 than it is on a standard 226. On a 226, I can't leave normal factory grips on otherwise the grip gets too fat for my hands. Hence my like for the E2 grip.
But on the M11A1, it's fine. And, the factory grips are also rough enough that I needn't worry about rubber grips either. Good deal!
Now, while shooting I tried some two handed and 1 handed double taps. I think I did the best I have ever done with it compared to any other handgun. It does take some concentration - but I was actually able to put some of the second shots in the central circle area. And even when it widened up, at it's worst it was equal to usually the best I can do with other guns.
Also - I am a HUGE DA/SA gun fan. So, at the gun store, I knew I would like this gun if it just worked 100%. And it did, of course. I think if I didn't have my Shield as my carry gun, I'd be tempted to carry this thing. It is obviously heavier than the Shield, though. On my bathroom scale, my Shield is 1.6 lbs loaded. The Sig M11A1 is 2.4 lbs. The Sig's trigger is preferential, but the extra weight would be noticeable when I usually carry my Shield with a Smart Carry holster and draw string shorts.
Because it shot so well with double taps, I considered making it my night stand gun. However, when I hold it and my 92FS, the feeling of the Beretta in my hand is still my favorite. And, it's so familiar. So, I'm not changing it. But< I will admit that I can do doubletaps with the Sig M11A1 better than any other gun.
