Things I liked: This is as close as you can get to the real thing in terms of weight, look, and balance. Lay it next to my real M&P and it is dead on unless you look from the rear
Things I would have changed: Make the safety designed by S&W function rather then designing your own so this can be used for actual perfect practice
What others should know: The blowback is "interesting" but isn't all that realistic since the real weapon's kick is so much greater I would save the CO2 for more shots. I can't praise this enough it is a great way to practice daily skills without any concern for range time or cost of ammunition. Well done weapon and priced to be the perfect practice gun. Accuracy like any other blowback is OK and more then enough to simulate real world use. I have easily 3K rounds through mine with no real complaints short of the desire to redesign the safety to something more functional. Mine is finally showing wear and tear on the black. A drop out mag would be asking for the moon at this price but the round mags are cheap, easy to use, and fit lots of models besides this one. It IS BTW single or double unlike the company's direction just pull the slide back and done.
Things I liked: This is super well built. No it doesn't have locks but at the price it has several holes for locks. I can easily fit 4 pistols in it so I don't look stupid walking into the range with sacks all over my back etc. HARD plastic is nice. NO need to mess it up with a solid core this way I can set the weapons up the way I like
Things I would have changed: The only thing I would change is to allow more layers of "pull the squares" and less eggcrates. I am a bit anal retentive and like to have cut outs for each gun each layer does not have "pull the squares" some have egg crates and some PTS would be nice to have more PTS. Otherwise for $20 this is PERFECT
What others should know: This will NOT pass FFA regs so don't try to fly with it. Even snapped shut anyone can pop it open or worse flying around the baggage claim bad things can happen to your precious weapons. Not sure if you tape the seams after inspection if they will clear it
