Product Information:
This gun has got to be one of the best performing pistols out there. I've had mine for over two years and it's still running strong. I do have had a few problems with it, but nothing too bad.

The main issue I've had with the gun involves feeding into the hopup chamber. There is a small ramp to take the bb from the mag to the hopup, it's made of metal, but it is really thin. On my HK45 this ramp snapped in half. I don't know how it happened, but I just noticed it one day. You'd think this would be detrimental, but I actually hardly notice it. Only when I spam the trigger as fast as I can, the ramp may not carry the bb properly and the gun will jam. But even then, most of the time I can dump a mag very quickly and shoot all the bb's perfectly. The other issue I have is with the slide catch. The metal on the catch itself and the cutout in the slide where it lands wears very easily and can eventually result in the slide not locking back with an empty mag. Mine no longer locks back, but it's partially my fault. The slide catch is not really meant to double as a slide release. If you power stroke the gun when reloading instead of thumbing down the catch, it causes much less friction and will extend the longevity.

As long as you take good care of the gun, clean and lube it often, it's one of the best sidearms on the market.

1. Insanely accurate at range
2. Great hopup (can lift .28's with ease)
3. Very comfortable to hold
4. Ambi mag release
5. De-cocking lever
6. Nice recoil and great gas consumption (I can get three full mags out of one gas charge)
7. High mag capacity (28+1)

1. Hopup must be adjusted with included key
2. Weak portion of hopup (didn't end up being an issue)
3. Slide no longer locks back
4. Orange tip is very difficult to remove (not an issue for most people)

Excellent bang for your buck!

Being a longtime HK fan, I purchased this a quite a while ago. - No negative experience yet.

First game I used it was in a CQB field as a primary, since my MP7 shot too hot. - Had no problem engaging players at 50 to 100 feet down the main straight of the course. The thing is absolutely capable of scoring a hit on a 5 by 9 inch target (which would be a face) at said ranges provided the hop-up is dialed in and you aim center mass.

I've slid it across rough concrete floors to teammates who have run out of ammo, dropped it (because my holster is rather crap) and it's barely scarred, where other guns have scratched to the point where the aluminum is visible, this one is still black as night everywhere.

Trigger is a beauty, trigger guard is large enough for gloved fingers to fit through, the de-cocker/safety is a charm, so are the hammer and the slide release, which are also easily accessible. Even though I don't used the slide release because the slide itself is textured every-which-where and I just rack it. Contrary to what I was thinking, the back iron sight and front of the slide have just enough space to rack the slide off of something, if you've only got one hand available for operation. + I constantly press check the thing because it looks very similar to the HK I've used in .45.

I hope this thing never dies on me and as of the moment it doesn't look like it will.

In conclusion, this is a fantastic secondary, not a bad primary and a must for every HK enthusiast.

- Durable

- Functions flawlessly

- Doesn't scar easy

- Easily worth the price tag of 155 USD.

- Very realistic (Markings all over the place, mirrors actual firearm's operation, recoil is noticeable enough to mention)

- Outside barrel + orange tip is polymer (but still sturdy)

- Plastic barrel has minor wobble back and forth (but doesn't effect accuracy or operation)

- Gun is really light without a mag in it (could be a pro)

Ok.. I'm new to the airsoft world but have a need for a pistol and carbine. So in my browsings of different pistols and carbines I came across this little gem. Now, I own plenty of real firearms so I expect anything airsoft that I get to duplicate/simulate the weapons I'm used to will definately be a shadow of the real thing.. but reading the reviews that have been written on this pistol made me sit down to add my 2cents..

First of all, I own one of the real ones.. not a replica like this, but the actual pistol. And I've got to say that my experiences with it have been exactly like what you all have been describing about this airsoft replica. Amazing!

Yes, the moment you pick up this weapon it molds itself into your grip... becoming an extention of your arm.. it's THAT good! The trigger action is superb,as is the weight and balance. The sight picture is perfect, the recoil is easy to manage, and the controls are all perfectly thought out and placed (especially love the mag catch). I grew up on 1911's and am still a big fan, but this weapon far surpasses that design in nearly every way.

So, just wanted to let you guys all know that the manufacturer must have done a truly excellent job on the design and manufacture of this weapon for it to so closely mimic the real thing. Well, except for that front sight coming loose issue that everybody seems to have.

I had originally planned on buying a 1911 airsoft pistol, but now it looks like I'll be getting one of these.. :)

IMHO: This is the perfect pistol. It only makes sense that this would be the perfect airsoft pistol too.

that loose front sight thing makes me a bit nervous.. I'll just glue it as soon as I get it sighted in.

Product Information:
The KWA HK45 is the best pistol anyone could ever own. The full metal slide and the ergonomic grip give the gun great weight and makes it feel awesome. The 28 round magazine is full metal and adds even more great weight to the gun when its loaded and will go at least 2-3 mags before needing another fill of gas. The blow back is very sharp and loud and feels great. The grip is very comfortable to hold and is nice and thick, I've held my friends 1911 and this at the same time and it makes 1911's feel very skinny and small. I very much enjoy trademarks and they are everywhere on this gun, even on the magazine. The iron sights with the white dots are very nice and makes aiming at a target super easy. I think this is the best pistol KWA has put out by far.

Feels better than any pistol I've ever held
Comes with thinner back strap if the original one is too thick for you to hold the gun
Magazine holds a ton and is very efficient
Trademarks everywhere!
Awesome weight
Beats any other KWA pistol
It has a small rail on the bottom for a light/laser

- Minor Things -
Pricey for a pistol, but totally worth it
Extra mags are expensive, like all green gas mags
16mm threads
Holsters are hard to find
Back strap is hard to change but I didn't have to

Product Information:
This pistol is an absolute dream! First of all the ergonomics of this gun are in a class all of it's own. All the controls are in easy reach of your hand and the contour of the grip makes as though the gun is and extension of your arm. This pistol is also one of the most accurate pistols I own being able to hit a torso size target at 50ft without any trouble. Although I must say that this gun as well as any KWA / High-end sidearm does require more maintenance than the norm, but if you clean and lube your gun on a regular basis it will be a reliable and accurate sidearm that will serve you well on the field.

- Amazing ergonomics with interchangeable back-straps included in the box.
- Fully ambidextrous
- Accurate
- Fps (pushing 350 with .20s and 335 with .25s)
- Standard picatinny rails, no need for an USP rail adapter
- Double stack magazine with 28 rounds.
- Gas efficiency, the NS2 system allows for just under 2 magazines for one charge of gas at room temp.
- Full HK trademarks, even on the mags.

- Slightly higher maintenance required, same as all KWA guns
- Front sight post can move or fall off, quick fix with some super glue.
- Mag release can be accidentally hit if not used to USP style mag release
- Lack of hard holsters, although can be found if you look hard enough.

Umarex HK45 OEM by KWA..
28 rounds
First thoughts on first time handling the gun just fit so well in hand (big hands) swappable back strap, picatiny rails no need for adaptors..
amidextious on everything except the saftey switch/decocking lever.

28 rounds, @ 350fps so awesome for pistols only
works for both left and right handed shooters.

Good to know that Bob uses one..

None that i have occured on the gun itsself... but when I got additional magazines for it check the BB loading area some machining issues was there on one that the BB wont go in at all.. not a dremel wont fix..

Product Information:
I've owned this for about a year now. It is comfortable and has standard rails that don't require an adapter. I used the smaller backstrap and found it made for a better fit. You wouldn't know if you were just stuck with one choice. Shoots right near the CQB limit of 350fps. Has been reliable and accurate. Good mag capacity at 28 rounds. There is some outer barrel wobble due to clearance around the front of the barrel and slide. That bugged me enough to carefully shim it with some strips of mylar tape to reduce this without impacting the free movement of the slide.

Good mag capacity at 28 rounds.
FPS right at the upper limit for CQB
Good overall performance.
Adjustable backstrap.

I found that the way I support this while using two hands sometimes causes an accidental mag release.
Not many holster choices if you are looking for hard (kydex or similar) GCode/Blackhawk/Blade-Tech or other holsters.
I chose this over a 1911 partly due to mag capacity. If the new doublestack 1911 mags were available then I might have have considered a Mark IV 1911.

Product Information:
After holding a couple of handguns and test firing them, I can say without a doubt that the HK45 is probably the most comfortable handgun I have ever held in my entire airsofting career. After racking up multiple kills and owning this gun for about a year or so, I feel that it's fit to review this weapon.

This gun can do it all; it works well as a side arm, but also as a primary for those engagements in CQB. It has a double hop up unit located in the barrel, making the pistol extremely accurate, even up to mid range engagements. With .25's, it was reaching the same distance as my primary M4. That was with the Hop Up adjusted only halfway. Imagine the range capabilities!

The magazine release, compared to that of a USP 45, is larger and easier to manipulate, making reloads extremely easy and fast. In my opinion, it's superior to the button release, mainly because I have smaller hands. The adjustable back strap is a great alternative to those who don't have small hands like I do.

I would talk a lot more, but there would be too much to cover. This gun is high performance, as expected from KWA. However, this gun also requires high maintenance (see below). Overall, this gun is recommended to the advanced players who know how to maintain their weapons properly.

- Double stacked 28-29 round magazines
- Hefty
- Comfortable and VERY ergonomic
- Blowback feels crisp.
- Versatile

- The take down pin can easily fall out. (Easily fixed with electrical tape)
- You might have to file down the notch for the slide catch, because it wears out over time. However, if you don't to have this problem, pull the slide back instead of pulling down on the slide catch.
- Front sight post can fall off overtime. Super glue it.
- The decocker/safety broke, mainly due to user error. I would advise against using the decocking lever to decock the gun. Just pull the trigger instead to prolong the life of the pistol.
