BROKEN Hold Open Latch
Guys,
My 1918 DWM Hold Open broke today. After only 5 shots the toggle opened as usual, put some rounds on the magazine but it never went to the front again. Dismounting the pistol found the Hold Open Latch broken in two parts... I used Geco 124 gr ammo, could they be the problem? Are they too strong? Where do you advise me to get a "new" one, in Europe? Thanks |

Wow...You have a camera that takes .PDF pics???
That's the first pic of a broken hold-open that I've seen here...Crystalline fracture...Odd... I would think that LugerDoc here on the forum could fix you up with a replacement...

Rich,
why is a crystalline fracture odd? Just what I would expect from a hardened part. But for sure he needs a new one.

You're right. I forgot that it would be hardened...CRS strikes again...

Hi Miguel and welcome to the forum. I hope that we can be of some help with resolving the problem.
Your photography is outstanding. In fact, it's some of the finest I've seen. I expect that you came up against our file size limitation when uploading them, which is why you chose PDF format, which allows larger files. This is not necessary, and uses quite a bit of space (about 3 3/4 MB). I've attached your photos to this post. To upload them, I resized them to 1024 pixels horizontal and applied 50% Jpeg compression. The total size is about 400Kb. On Ammo suggestions, we always recommend standard velocity 115gn ball (full metal jacket) ammunition. Your GECO ammo might have been "NATO" power, which is loaded for machine guns and is too high a velocity. It's possible that your recoil spring needs replacement. Check to see how hard the receiver is hitting the back of the frame by putting some masking tape there and looking for compression marks. There are several levels of coil count and thickness of the spring which yield different levels of resistance. Look at our FAQ document for details. As Gerben mentioned, you can shoot the gun without the hold open. Just be sure to remove the broken part and it's spring before loading and firing the gun. Of course, it will close after the last cartridge is fired. The replacement hold-open part and spring will probably require some hand fitting. Can anyone with a metallurgy background comment on this part failure? It looks from the photos like the heat treating may have been uneven (note the fire blue color which fades before the right angle that failed). Marc

This horse is about beaten to death- just buy another hold open.
You tagged a question to an old thread elsewhere- asking if it could be repaired. The short answer is yes- any good welder could "repair" it. Then it would require re-shaping and re-fitting to the pistol. The big question would be how durable is the repair in service; it could easily break again- in the same or another spot. Which brings us back to - buy a new hold open.

Does LugerDoc ship parts like this to Europe?
- - - - Over on Jan Still's forum, someone else is replacing a hold open on a Mauser gun, and is showing a part with the same "24" number on it... Seems like issues bunch up... This is one of several "hold open" issue threads in the past week or so... I do see Miguel's post toward the end of that thread... http://luger.gunboards.com/showthrea...pen-latch-WWII

Bummer!
Have you tried these? https://www.google.pt/url?sa=t&sourc...TwYR4kbadM7H7Q PS. My BYF 41 is # 8024 So guess the number on the holdopen. |

CDS does indeed have lots of parts we would be interested in. You're lucky to live in the EU because they don't export to the U.S.! I have been acquiring mostly Erma and some Luger parts from them for a few years, but I had to establish a proxy who lives in Oberndorf. I send him a list and he buys them, obtains an export permit, and sends them to me. Considering three shipping charges, international check-cashing fee, a proportion of the permit, and something sent to my friend to make it worth his while, my customers wind up paying just about double full retail for any part. In most cases it seems worth the expense and trouble, because otherwise their guns would be paperweights. CDS was my last chance to obtain certain parts, as stock of U.S. sellers is depleted, but even they are running out of some components, which are now not available NOS anywhere on earth. As G.T. would say, they're made of "unobtainium"! Miguel, You will not be happy with their answer, as above. They are also weird to deal with, kind of snotty, condescending, and dismissive. Not particularly friendly.

I used the Geco 124 gr because they are the available on the market, now I see that they are used for IPSC and maybe they are too strong for my old P08. Now I am seraching for the Winchester 115ge, 363 m/s velocity. Anyway, I don't understand how a strong ammo can break the hold open, because if the ammo is strong and the recoil spring is old and weak, the velocity of the breech going to the front, to hit the hold open couldn't be bigger than with a weak ammo and /or a strong recoil spring, don't you think? If my logic is correct, the break has no relation with the ammo nor the weak spring but maybe weak or defective HO |

Wow! 4 in 20 years; that is one every five years and in a real shooting environment.
I probably lose one every five years; seems I lose or "misplace" a part every day-though sometimes I find it later in the strangest places. Seriously, every thing breaks sooner or later; however, I don't see the "power" of the round having any real effect on the hold open.
