Semi-Auto Pistol slide doesn't cock hammer..?

    My pistol (the French Unique Model 52 22 L.r.) is supposed to be semi-automatic. It is not. When a round in the chamber is shot the slide goes back and the empty round is released and a new round is put in the chamber, however, the slide does not go back far enough to pull back the hammer for the next round.
    What causes this? Has anyone else had this problem? Anyone know how to fix this or possibly what part I need to replace?
    Thanks for your time!

    I'm most definitely not a gun smith, but, if it were mine, the first thing I would do is replace the recoil spring. It sounds like it may not have enough power left in it to fully rack the slide.

    Maybe one of the more expert members here can give you some other/better ideas.

    Thanks for the reply CA357!
    I was thinking this was probably the issue, I just wanted to get a second opinion.
    If anyone else has any input it would be greatly appreciated! :)

    I've had this problem on a couple of pistols, none a Unique though.
    Pre war 1911 in .45 "National Match......and a French M-1935A in
    7.62 Long. In the case of the .45 it seems a previous owner had
    tried to get the trigger pull too light by filing on the full cock notch
    in the hammer. A new hammer fixed it.

    The 1935A suffered from about the same thing......It was a phospatte
    finished WaffenAmt Marked pistol and had been poorly assembled.......
    I sold this one because of its markings to a collector.......Suggest you
    look at the hammer.

    It cocks manually.
    Is the recoil spring "binding" or installed backwards?
    What ammo are you shooting?
    Enough lube on the rails?

    My PPK/s had the problem when new. Tried a box of high velocity and the thing would work (Stingers should not be used as the casing is different than standard LR).

    Now that recoil spring has "loosened up" a bit and I keep it cleaned and oiled, I have no problems.

    The recoil spring is not installed backwards.
    I'm shooting 22 L.r. Ammo by Federal.
    Im pretty sure theirs enough lube on the rails.

    Thanks for the suggestions :)

    I shy away from Federal's. Try a different brand.

    You might try some CCI Mini-Mags. They have a little more "oomph" than standard .22LR.

    I don't know anything about your gun. If it's older, make sure it's OK to shoot higher-velocity loads.

    Might be a dumb question on my part as I don't know the gun but is it a double action only?

    JPyle, the only dumb question is the one not asked.

    That handgun works like a single action. When you pull the slide back manually to load, the hammer is cocked. The slide should cock the hammer each time you fire.

    Does the slide lock back on the last round? It sounds like the recoil spring is not allowing the slide to come back far enough. Might be due to needing hotter ammo, Spring is too heavy, improper lube or dirt.The spring is binding and not allowing the slide to move properly. Let a gunsmith look at it. They should be able to find and solve the problem pretty easily.

    Damn, ya learn something new everyday...the French made a .22lr pistol? :confused:

    Anywho, I concur trying the CCI .22 ammo with a little more push and if it continues to do the same, take it to a gunsmith as stated. We have a few good ones here on the forum. But this sounds more like a "hands on" function/inspection/repair to me.

    The odd thing is that it does, so the slide is going back far enough to pull the hammer back for the next round, however, for whatever reason the hammer isn't staying back.

    Im no expert or gunsmith, but unless I'm missing something it sounds to me like it could be hammer follow.
    The hammer is being cocked by the slide but the disconnecter or a worn sear is not allowing the hammer to stay back until the trigger is reset and pulled again.
    If that's the case it's possible that it could go FA on you.

    Have you tried to recreate the malfunction by hand(dry firing)?
    If not
    Make sure it is unloaded and there is no ammo in the area. Then check it again.
    Point in a safe direction and squeeze the trigger, and keep holding it to the rear.
    The hammer should drop.
    While continuing to hold the trigger to the rear, pull the slide fully back and release the slide.
    The hammer should remain cocked and you should have to release the trigger(you should hear/feel a soft click as it resets) Then pull the trigger again to get the hammer to fall.
    If you hadn't tried this, it may clue you in to the source of the problem.
    Worth a try

    I believe we've found the problem. I continue to hold the trigger after dry firing and pull the slide all the way back and the hammer is pulled back again, however, when I release the slide the hammer goes forward along with the slide. Thanks for the help.

    I suppose the next question is how do I go about fixing this..? Should I take it to a gunsmith, or does this mean a part is broken that I should order and replace myself?

    It could be that the spring for the sear is weak or the sear and hammer were worked on by someone before you.

    Recommend that you take it to a smith. You may want to check the firing pin after dry fire. Dry firing a .22 can flatten the tip and create other problems.

    Sorry to bring up an old thread, but I finally figured out the problem. The pistol is missing what's called a 'disconnector'. I'm not too smart when it comes to guns, so I didn't notice it was missing. According to the Internet, this pushes the trigger bar down so you have to release the trigger before you are able to shoot again. Apparently removing or modifying this piece usually makes semi-auto pistols full automatic, thankfully this has not happened to me. I'll be sure not to take it out to the range until I order and install this part.
    Thanks again to everyone who helped. If anyone ever needs any info (such as the original papers that came with the gun), feel free to message me and I'll be glad to send them to you. Have a great day!
