Things I liked: This gun is a great replica all around. It fits in my paddle holster that is technically made for the real steel version. The weight is nice, but a little too focused in the magazine. The trigger is double action, as expected from nonblowbacks. While it is smooth, It is very long compared to others. Guns such as the HK USP have a much better trigger feel. You adapt after a while though. Because I use a tac light in my normal set up, the weight is much better in my opinion. It keeps weight in the barrel to help steady the gun. The sights are great, although hard to see in a dark room. The gun is extremely accurate with low recoil. I would suggest .20g BBs; they get acceptable distance. Anythin higher, even .23g, start to lose too much velocity. The magazine is all metal, and very realistic to the weight of a loaded mag. Overall a great gun. Trademarks are excellent, although not 100 percent accurate. A real M&Ps markings differ slightly, but unnoticable. Fantastic price!
Things I would have changed: I would add a more durable finish to the magazine. I've already lost paint in areas that come in contact with the frame,although i dont mind it. Also, an ambidextrious safety. The safety favors to the right hand. Being ambidextrous myself, it helps to be able to go both ways. Tho only other thing I would improve is the trigger pull.
What others should know: Be aware that the girth of these magazines are larger than most other gun models. It makes inserting them into mag pouches on the difficult side. I would suggest buying multiple mags, even though they are pricey. I.m about to order my third, which really helps on the battle field. Also, don't store magazines upside down. This is a problem for most mag pouches, but BBs tend to fall out of the mags if they are upside down. A worn out piece of tape helps for easy removal.
