I purchased an HK45 about a month ago, and right out of the box it worked great!

Now, recently, it's been having loads of problems...

1. The Pin that holds the slide on the gun moves around while shooting. So much to the point where the slide doesn't lock when there isn't a round chambered. The pin has also fallen out WHILE shoot before which has caused the slide to literally slide off the lower frame of the gun. Yes, this has literally happened.

2. BB's no longer feed into the gun. For some reason, the part that pushes the bb's through the inner barrel no longer comes in contact with the bb's. This means that the bb stays in the inner barrel (not being shot) and other bb's continue to load / feed / etc and jams the gun.

3. The part of the slide that catches the pin (to lock the slide) is already been worn down so instead of a hard "square" edge it's now a rounded edge.

I've had this gun for a MONTH and have probably played 10 games with it and it's already completely broken. I take AMAZING care of all my guns and gear...this gun just feels like it was built terribly. Don't get me wrong, when the gun actually WORKED, it worked amazing! But there is no durability in this product. Gun is completely broken after A MONTH? That's ridiculous.

I don't know if my gun is still under warranty since I have removed the orange tip...but I feel like KWA should do something about this. I spent $160 on a product that worked for a month. I submitted a help ticket but thought maybe the forum community knew if this was a "common" issue with HK45's or shared some of my pain (ha).

1. Put a tiny, tiny amount of JB weld or something similar on top of the part of the slide cath that is supposed to be locked underneath the slide and is supposed to keep the slide catch in. Sand in down until the catch moves like it's supposed to. You don't need much JB weld on it, i only have like less than a milimeter.

2. If what your describing is what i think it is; replace the cylinder and polish the feed ramp so bbs don't get caught up on it.

3. Nothing you can do. All of my HK KWAs do this. Its just design and quality of the aluminum. My MK23 is so bad that just the lightest tap or movement will cause the slide lock to trip.

My HK45 had a serious jamming issue, to the point that the feed ramp snapped in half. When I polished the feed ramp all the jamming issues stopped and the gun has been performing flawlessly.

My HK USP has been through hell. The only thing I've had to do is replace the slide stop/catch lever.  I used propane for six months, didn't always clean it between game days, dropped it, lost it, found it and  bumped it into walls.  It has always fired.

You should at least call to see what your options are. Technically you don't have a warranty once you remove the orange tip. You also need to have an orange tip for shipping purposes. 1.626.581.1777 It won't hurt to call. Maybe they can work something out.

Though I appreciate the answers and feedback, I feel like KWA should be doing something about this.

I live close to their HQ (I'm in Los Angeles), so I wouldn't need to ship anything...but ugh, this is just ridiculous.

My tech said my cylinder needs to be replaced (awesome) and I'll try polishing the feed ramp to see if that helps.

As far as JB-Weld on the pin...that doesn't seem logical considering I still have to remove the pin to remove the slide from the gun. I was thinking "Thread-Seal Tape" would be a better bet? Thoughts?

As far as the slide itself...should I give up on it ever locking again?
I mean seriously...a MONTH? ugh. I feel like I've been screwed over.

You gotta give KWA a chance. Call them and see what they will do instead of feeling screwed over.  From what I have experienced and read here, they are more than fair.

Alright, I'll give them a call tomorrow explaining what's up

Mine stopped locking back when empty as well because the slide notch wore down.  I simply filed the notch square again and works fine.  But, it does seem like the metal could be a little "harder" to resist wear.  It wore out with less than 2500 BBs through it.  But, again, filing it square was quick and easy.

the problem with making the metal harder, is that it would start to wear out the slide. and that would be a lot more to replace a slide (usually about $60.00) than the slide catch for about $2.50-$5.00 :)  the design's of KWA pistols are very well though out. almost everything is done for a very good reason.  (accept those damn polymer guide rod's in the gen.1 atp lol)

as far as holding the pin in goes, you could try some plumber's tape? i guess it could work.. but jb weld would work better. i think when the previous person to suggest jb weld said what he did, he meant to build up the pin just a fraction of a millimeter so that it does not slide out. not to actually lock it into the body with jb weld.


P.S. sorry for double post, feel free to combine if you can moderator's

I think you misunderstand.  The problem is the metal used for the slide.  It is the slide notch (part of the slide) that is wearing down at an angle so that the slide release lever will no longer catch the slide when the mag is empty.  Rather than keep filing it square, my plan is to treat the metal on the slide to reduce the wear.

Thank you. My slide notch is also rounded -_-
What did you use to file it square again?
Also, once you file it square, isn't it just gonna round off AGAIN AND AGAIN???!

OptimusKMG, I will definitely disagree with you 100% that "everything done to a kwa is done with good reason".
The lemon they sold me is clear proof of that.

I used a small, fine square file.  It took about 2 minutes to do.  Just go slow and make sure you keep it square.

Yes, from what I can tell, the wear comes from disengaging the slide release lever.  Like I said before, I am going to try and coat the slide where it catches so it is not metal on metal.  Don't know what I'll try yet.  You can also hold the slide slightly to the rear when you activate the release lever that way it will not create the friction with every release of the slide.  If I come up with something appropriate to apply on the slide, I will post my results.

I was talking about putting a tiny ammount of jb weld on top of the slide catch, the part that you have to line up with the little notch in the slide to remove the slide catch. This will prevent the slide catch from falling out while shooting.

So is this a common problem with the slide catch wearing out and or falling out? I just ordered an HK 45 but thinking about. Canceling my order like in 45 mins.

This is not a common issue, don't let this scare you away from the HK45.  I have one myself and I love it.

Ive haven't had it wearing down yet, it just would fall out sometimes and it bugged me so i fixed. I also pull the slide to release the catch instead of pressing the slide release, that's probably elongating its life.

I opened a ticket and someone got back to me. Hopefully I can get this resolved...but like I said, it's more than just the slide catch wearing off. The gun doesn't even FEED anymore. From further inspection it LOOKS like the feed ramp was causing jams which in turn caused the cylinder(?) to break / warp / etc. One problem caused another problem etc etc etc

So, even if I file the slide to a square again so it catches, the PIN itself moves around every time the gun shoots to the point where the pin falls out. I still can't figure out why it does that, other than it doesn't lock into the opposite end tight enough?

From what I've seen around the boards and at my local fields in So Cal, it does seem to be a common issue.
I am in no way trying to tarnish the KWA name, considering I loved my USP and I absolutely LOVED my hk45 for the first few weeks...however I have been seeing a lot of the same problems popping up.

I appreciate all the help on the boards aswell as KWA and I'm hoping we can get this problem resolved so I can continue using KWA products.
