No lock back on last round? FINN Luger *UPDATE 4/21*

redbear · 04-08-2007, 04:32 PM

I rececived a 9mm Finnish luger recently as a gift. Thankfully, I do know the provinancee of the piecec; it is one of the Finn lugers that came from AIM.

It's a somewhat odd piece, though.

First, it has a 4" barrel. More curious, at some point in time it was done up like a BYF [the so called "black widow"] luger; All parts blued [truly blued, I checked], black plastic grips [they are the originals, I also checked]. It bears the [SA] finnish property mark on the left hand side. All parts are either un-numbered or are matching; The Takedown lever, barrel, trigger, toggle arm are all marked with the last two digits of the serial number. The pistol does show some evidence of being refurbed, perhaps several times, by the finns. The toggle is amrked DWM, and it bears the import mark of TG gunns discreetly on the right side, like all these recent finns do. The bore is excellant, and she shoots amazingly well.

The only issue the pistol has is that when firing it does not lock the toiggle open on the last shot. It will lock if you cycle it by hand.

I was curious if anyone has an idea as to why this will not lock open? Also, any more information you could give me on this curious gun would be helpful. THANKS~

UPDATE 4/21~
Well, I sent my Finn Luger off to member "Lugerdoc" to check over the main spring, the bolt hold open and give it a general "once over" in case there are any other issues that might crop up later that I'm unaware of... I figured this was the best thing to do, as I don't consider myself any kind of luger expert at all.

Heard back from hi, today, and he already has it fixed!!! He says the issues was basically all the spring, and he made a few small adjustments as well, and polished the feed ramps. Can't wait tog et it back and shoot it proper next to my TT-33's... kind of an Eastern Front Shoot out, if you will!!!

Hi Joe,

Welcome to the forum...

I just got a 4" Finn like yours. The 4" barreled M08s are hard to find.

It sounds like your magazine button isn't contacting the hold open and pushing it into postion. Have you tried it with a different magazine? Does the mag spring feel strong?

Ron;

I've tried two differant Finn mags [the one that came with the gun, and one from Numrich], and a German mag [borrowed from a friend], and a brand new MEC-GAR mag I bought from CTD. All mags fed 100%, but none would lock back on the last round. now, the gun WILL lock back if you cycle it by hand, on any mag, but will NOT lock back when actually firing on any mag.

I haven't tried changing any magazine springs, but with the new mec-gar I didn't feel that would matter or help... I could be wrong though, I'm no luger expert ;-)

I DID think that perhaps my toggle felt SLIGHTLY stronger than a friends luger... unsure if mine is stronger or his is weaker.

Ron Smith · 04-08-2007, 05:05 PM

If you have tried other mags with the same result. that pretty well rules out the magazine aspect.

It sounds like the main spring is pretty ridged. It's probably not allowing the bolt to retract far enough to engage the hold open. What kind of ammo are you using?

You might try checking with Tom Heller , forum name "lugerdoc". He has Wolf spring kits for sale. It may require a different main spring to function properly.

I'ev tried Fiochi, Blazer Brass, Cor-Bon +P, GoldDot +P, POW'R'BALL +P, and Winchester White Box.

I'll send Tom a PM and see what he thinks and if the spring kit might help, thanks for the heads up~

Ron Smith · 04-08-2007, 05:58 PM

Part of your problem could be the hot ammo. It's cycling to violently to let the hold open to engage. The Winchester shouldn't be too hot, but the other ammo listed will beat the Luger to death. Cor-Bon is way too hot for it.

redbear · 04-08-2007, 06:24 PM

The Cor-Bon +P, GoldDot +P, POW'R'BALL +P were all only one box each [which was 20 rounds per box, so not a whole lot was fired this way]. I was thinking that it wasn't coming back far enough, so perhaps hotter ammo would help... it didn't. I've put probably 2 boxes of WWB and 5 boxes of the blazer brass, and one box of Fiochi. It actually grouped BEST with the blazer brass, but NONE would lock it back.
