I agree on the positive reviews of the shield 40. bought one on an impulse when it was staring me in the face at a LGS. Shot it a couple of days ago. has great accuracy at distances Ill shoot; and the recoil isn't any worse than my other guns. ALL small framed compacts or subc's. IE G27, kel tec PF9, kimber tac ultra II (aluminum frame .45). I did shoot a little bit left like some others were saying, but I think its my hand placement or something in my grip. I concentrated a bit more and repositioned my hand and made sure I wasn't squeezing too hard, and was a bit more accurate with it. 7-10 yards, 2-3" groups with the majority of the holes touching. works for me.
I was expecting the mag drop problem, and it didn't show up in my 100+ rounds through it. maybe it will after another trip to the range, maybe not. Im not that worked up about it, if it does. Ill either dimple the mags myself, or send it back. as long as they fix it, if it needs; Im ok with that.
Best thing I can say about the gun is the price and feel, fit, and finish. wish they offered a factory night sight option, tho.
I looked at a bunch more guns today at another store, and for the cash; the only other gun that might be close in bang for the buck IMO is my kel tec. 225otd was a steal. BUT I might sell that, since I see myself using the shield for my edc. I like everything about the pf9, except it has a bit more play in the slide and frame fitment than I like. probably doesn't affect anything, accuracy or wear, but I hate that I can feel it wiggle around, lol.
