This is a good gun and generally well-made. And it is fun to shoot. It's a little heavier than it looks. I am usually a generous reviewer, but I did deduct one star for a couple of reasons. The finish is just OK. There's a metal edge near the barrel that's really rough and looks more torn that cut. Also, the grip surfaces are little more than stickers - secure but the look is a little cheap. Still, it's fun, looks cool, and an inexpensive option for shooting this caliber. I don't regret the purchase.

Felt a little heavier than I had anticipated, very well made, sturdy, will probably get years of use from it. Accurate right out of the box. Only shot FN TMJ ammo from Buds. Ammo is a bit scarce right now (pricey) that will change in time once everything settles down a bit. Would recommend this as a buy, gets plenty of looks at the range. Now I want the FN Herstal FiveseveN Bud's Item Number: 60445 waiting till they return to stock. in the meantime I'm looking at an MPA top cocker .45

This is a great gun. Not too loud. No recoil. Accurate as any gun can be. Put a handle on the bottom rail with stand extension. Shoots as accurate as a rifle. I hope Masterpiece keeps making these type of weapons. Won't disappoint.

I just got the new MPA57SST chambered in 5.7 x 28 mm, which is my third Masterpiece Arms firearm in two years, and I must give kudos to them for this fantastic new firearm. It functioned flawlessly right out of the box and has even less recoil and barrel rise than a 9mm M11, probably due to that great new muzzle brake. My new MPA57SST was the center of attention down at the firing range, and all the firearm enthusiasts were very impressed with the functioning, handling, affordability, and accuracy of this latest cartridge for the Defender line of firearms. Excellent job by MPA and I look forward to additional purchases of new Masterpiece Arms products in the near future from Buds!
