KJW KP-13 Full Size Polymer Frame Gas Blowback Airsoft Pistol (Color: Black / Add CO2 Magazine)

"Super nice gun with a nice crisp kick! Grip feels nice in your hands and target acquisitions is quick with the fiber optic sights.

"Just recieved mine (black) today. The overall fit and finish is very nice so far. It has fired and fed with my WE Tech 17 mag and extended mag. The WE mags are a much cheaper option for the gun. And as per usual for other guns, the extended mag kicks quite a bit harder. I bought this gun due to a small nub on my WE 18c hammer snapping off. This gun is an upgrade from any WE G-style pistol. The ergonomics of the pistol grip is amazing. It keeps the same grip angle but just a more suitable silhouette to fit in the hand. Even with smaller hands, this gun feels great. Putting the mag in the gun and shaking the gun, there is hardly any rattling or wobbling. It is considerably less than my old 18c. It hardly rattles or makes a noise with light shaking. It only makes a sound when you use you're entire arm, and I'm sure you winy ever be shaking the pistol on the field. The barrel fits tight in the hop up and a little bit of the bucking being pushed down is seen in through the barrel with the hop up all the way off. Therefore, I'm sure this will easily hop bbs. The trigger is heavier than my WE trigger but a crisp break and reset. This is just the overview because I have not used the gun on field yet. Look out for another review!

"This is the best "G Series" type pistol you can get ( I am waiting on the Umarex G17)

I have many G Series guns - Tokyo Marui, Army, Stark, WE and AW (G17, G19, G26, G34, VX)

This one shoots the best. Has the best sights. The slide ALWAYS locks back. The mags hold a charge for all the BB's

The slide is gorgeous, the frame is stipped on your index finger points and looks great too.

Shoots harder than a Marui. Shoots way farther than a Marui. Slide locks back every time UNLIKE a We G Series.
I love love love the fiber optic front sight.

This thing hits what you aim at, looks great and functions flawlessly. As mentioned it can take TM, AW and We mags.

THE BEST, 6 STARS!

"Terrific pistol. All the features of your G series but with a better and more ergonomic grip.

Shoots very well with better than average range and accuracy (after the hop-up sets in). Mine seems to like .25's the best. Sights are very good and the trigger has a pretty crisp let off and short re-set.

The other great thing about this pistol is that it uses all KJW/TM and WE G series magazines (CO2 and Green g\Gas) as well as all Guarder (and most other brand) TM G series up-grades including slides, barrels, triggers, sights etc. etc.. The only major difference is the magazine release, which is metal and has a different shape from any of the other G series pistols. Its also better.

I've made 2 custom pistols using the KP-13 as a base and they came out super. The pistol also uses most G series holsters as well.

Used as a stock KP-13 or the base for your own customization, you cant do much better than this. Highly recommended!

"Very nice gun, I highly suggest getting the Co2 magazines. I dropped the gas magazines and a bit of dirt got in them and completely stopped working. Its a very high durable gun, dropped and it the wall a couple times on accident. Still in very good working condition.

"So unlike other people reviewing this KP-13, I didn't have the best experience with mine and will be returning. Keep in mind however, this could just a defective model (that shouldn't happen but take that as you will) as I picked it up from an in person Evike store in Antioch. Overall a pretty disappointing experience because I really liked some features about it. (I'm pretty strict about slide action and how smooth it is, and for a GBB pistol costing 125 USD, I expected better. I'm a sound designer so the mechanical nature of these GBB pistols is important to me. If it shoots straight, that's all I need, so I'm not the person for accuracy questions.)

Now for the Pros and Cons -
Pros:
- Pretty good build quality!
- Great ergonomics and the design in person is sharp and tactile.
- Slide serations are clean and grip nicely.
- With Green Gas, Gas Blow back is decently strong and satisfying. Good sound and accuracy. Goes where I want it to. Had to do minor hop-up adjustments but that's natural.
- Solid accuracy. Shoots straight and hard.
- Mag release is quick and mag insertion and extraction is satisfying and smooth. (Mag release button is a litttttle sluggish to get to the click, but overall solid. )

Cons:
The guide rod spring responsible for the slide reciprocation fails 20% of the time and is too weak to fully bring the slide forward sometimes.
(I then have to bump the slide forward tactical style, but it's still annoying)
It feels like the spring itself isn't strong enough to bring the slide forward.

The slide action itself is stiff and feels "un-lubed" EVEN after applying ample lubrication in multiple places. The first 1/4 of the slide has a really strong stop (3-4lbs of force or so it feels like it) before you go past the hopper barrier. Overall unappealing action for me.

The Slide release is another issue but this is mainly personal preference. The way that it's ergonimically placed is JUST in the wrong spot that my fingers rest so I have to readjust in order to hit it. The slide release mechanism itself is also slightly clunky. You have to pull down to release the slide but the way the slide release is made, it makes it annoying to keep your fingers on it.
The slide release feels like a poorly made aftermarket part :/

Overall, my experience with the KP-13 has been
Meh. 5.5/10

It's a good looking pistol and I would have really liked it to work better but it's not going to last for me.

I'd be eager to test out a brand new out of the box model as I don't think this is fair to the KP-13. Great looks, poor mechanical performance
(Again, this could just be this specific model but I'm still disappointed so take my review with a grain of salt)

"Let me start by saying that I like KJW. I run a KP07 with a lot of my loadouts, but wanted something lighter and that KJW made a threaded barrel for. Out of the box, the return spring was so weak that the slide would get stuck midway through its return motion.

Ive since modified it with a threaded barrel and enhanced recoil and trigger spring. However, Ive found that the KP13 is quite temperamental. It might work for a few shots, but then experiences issues.

Long story short, the KP13 didnt work well out of the box, and has yet to reliably work with the enhancements. Its possible that I simply received a lemon, but Im quite disappointed with this product as compared to my KP07.
