Oh, and I can carry the Shield the same way I carry the BG. My favorite way to carry it is in the watch pocket in my jeans. Just like I do the BG. It fits well enough that the trigger is covered and I don't need a holster. I'm going more and more to appendix carry for all of my guns when I can, and the Shield is great for that.
I've got the .40 and I really like it. The 9 wasn't an option, I'm just partial to the .40 S&W. Not at all "snappy" like most report with that caliber. Easy to control and the most comfortable to conceal of any I own, and that includes the BG .380.
Had my Shield out yesterday. Put about 200 rds through it. My particular gun doesn't seem to like the aluminum cased Blazer stuff. It did fine with both Winchester white box and even the super-cheapo Tulammo. It also seemed to like Hornady's Zombie Max ammo, but that stuff is too expensive to be shooting it a lot.
It is really an exceptionally pleasant gun to shoot, especially considering its small size. Quite accurate too.
The Shield is a great addition to the M&P line and it has the best trigger of that line. It's thin but feels very good in hand and is extremely accurate. I put 300 troublefree rounds through mine and just sent it off to Robar for thier NP3 electroless nickle finish since this is a carry gun. Try one and you won't be disappointed.
It seems just about every gun in the M&P lineup is nothing short of outstanding. I got ahold of one of the early batch Shields and am extremely satisfied. Great gun. Carries like a micro, performs and handles like a medium compact. And 8+1 is excellent capacity given it's size.
In the next few weeks I'll probably add an XDs45. We'll have to wait and see which wins out for EDC. But I have a feeling my trusty old PF9 will become a bit obsolete at that point.
I've owned a Shield for several weeks. 100% satisfied. I bought mine a few days after news of it hit the web. Thus far I can offer up exactly zero deterring factors about this gun...but there's plenty to love.
