I bought this gun about a month ago and have since then used it in some small skirmishes and some IPSC-style run-n-guns. My first impressions were mixed but after using it and becoming familiar with it, I now love it. I love it so much, I wrote an epicly long review of it to show you how great it is. I'm an older guy with lots of real steel trigger time, so I'm hard to impress too. Seriously, if your looking for an airsoft gun in this price range and even a bit above it, buy it. Just buy it. It's great. Seriously. Click the add to cart button because I promise you that you'll like it.
Build Quality -
The build quality is very impressive. The metal parts are made of high quality metal and laser etched and the plastic parts are durable and well shaped. The functional safety and decocker are really nice features. The internals are durable and very well made and the NS2 gas system is great. The magazines fill cleanly and lock in nicely and are pretty durable as well so there's no need to worry about breaking them by reloading too hard.
This gun has a 1911-style grip angle and I, like many other real steel operators, like that more than, say, a G-series gun. The grip strapping isn't made as nicely as the real steel gun, but they definitely aren't made poorly by any means. The mag release, like the real steel counterpart, pulls down instead of pressing in. It takes some getting used to if you've trained with other pistols, but I think it's a better system. The gun has nice weight to it as well; not heavy but night light. The slide is machined very well and cycles smoothly. The slide has a very nice feel when racking and makes a very pleasant -clack- when sliding forward. It's pretty loud too and sounds very nice. I know some of you guys (and girls) don't like the plastic outer barrel, but the metal slide cycles great against it and I trust KWA that they know what they're doing.
I've used this gun with a few different brands of green gas and also with propane. At first I was using a weak can of green gas and was shooting about 315fps with .20g BBs. I tried another can of green gas that performed much better and I was able to shoot through both sides of an aluminum can (which according to some places means the BB is traveling at about 350-370fps. On propane.... the thing is a monster. I was shooting over 400 with it. Now I wouldn't go and use propane for the life of this gun, but I bet you probably could. I've been using a mix of propane and Ultra Elite gas (I found it to hit a little harder than UHC green gas and has a little more lube. Maybe too much lube when using just Ultra Elite, but just enough when mixed with propane).
It's accurate. Since I was chronoing so high, I opted to use heavier BBs at either .23g or .25g and this helped with keeping the BBs on track. The hop up is very easy to adjust, though I didn't have to make any adjustments out of the box.
Other Thoughts -
This gun isn't very upgradeable yet. Then again, there isn't a lot you need to do to it. The NS2 gas system hits very hard so I don't think you'll be needed more power. There is one company (EdGi) that makes a 6.03mm tight bore barrel available directly from KWA. I'm considering it, but since I have replaced my outer barrel with a non-theaded barrel, I'm not sure if it would fit.
KWA is the American facing side of this company (KSC being the non-American company) so the manuals and website and all that are in real actual non-typo-filled English. The customer service is great and they have a forum that is staffed with real live KWA employees and other airsofters that can answer questions.
-High FPS. Everybody loves high FPS, but only if the gun also has...
-Beautiful design. At least I think so, but I very much like the look of this gun and it's real steel counterpart
-The company that makes the real steel gun on which this gun is based uses a proprietary rail system. If you want to attach accessories there is a pretty short list of accessories for it, and most come at pretty high price tags.
-Features a 16mm+ (clockwise) threaded barrel. There are few barrel extensions that will fit should you choose to use one. King Arms makes on and KSC used to make one for the MK23.
-The front sight is rather tall. This is so operators can see over a suppressor. I think it looks kind of goofy. You can replace the front sight for $8 from KWA though if you feel the same way.
-Uses a lot of gas. That being said, it takes a lot of gas to fill the mag up but you get a lot of shots out of it, so it isn't really wasting the gas.
