Another DES 69. This one is strange: has had feeding problems. This seems to be because, compared to the other one, the face of the breech lies further to the rear. Can't remember the distance, but in the order of 1 or 2mm. This means that the feeding round jams obliquely in the breech, before it has cleared the magazine lips, causing the top of the feeding ramp to indent the underside of the bullet. It must be a manufacturing defect. When time permits, I'll machine it back and attend to the chamber, as required.
Hi everyone,
A newcomer to the site here. I was just doing some googling around and ended up here, and noticing there are quite a few fellow Unique shooters, decided to register.
I know the posting I’m replying is quite aged, but just in case someone is still wondering about this. I had exact same symptoms, but no reference unit so I don’t know whether the breech location is incorrect. I wondered this for a while, until I noticed that the jam always happened with the last round of the magazine. And a little further investigation revealed that it was also with one of the two magazines, so obviously, it was, in my case, mag related. The follower is rather soft aluminium, and the rim of the last round eventually digs into the material, creating a little notch that causes slight drag when the slide tries to push the round out. Carefully filing the front wall of the notch (just the buildup of the material pushed forward by the rim), you can smooth it out enough to prevent the rim being ever so slightly jammed to the follower. In my case, this cured the problem permanently.
About the ammo you feed to your Unique DES 69. I’ve found mine to be a bit finicky about its diet. Everything shoots fine from the accuracy perspective, but it certainly requires a bit more power to cycle perfectly than most other target pistols I’ve shot. Cheap rounds like CCI Target Standard and Geco Pistol work fine, but many softer loads don’t fully cycle causing stovepipes or failing to pull the next round from the mag. And of course it makes no sense shooting anything more powerful than you need to cycle well, just wearing out the gun and generating more recoil. What are your favorites? Any similar problems?
