Unable to Slingshot my G34 Slide.


October 2, 2005, 11:28 PM
I just got my 2nd G34. I have magwell, THE Accessories scope mount, tungsten guide rod, and Ghost Rocket disconnector. When I load a full magazine, I can not use the slingshot method to release the slide, I have to use the slide lock lever. Does anyone have any idea what could be causing this? I did have to fully disassemble my pistol to put in the Ghost Rocket, but I'm pretty sure I put it back together properly? Could it be that the scope mount is somehow screwed too tight and is causing the slide lock not to drop? I'm thinking it might be the magwell maybe binding the bottom of the 10rdn magazines therefore even though the magazine seats, the follower isn't actuating the slide lock? The pistol shoots dead on , but I can't slingshot my slide.

When you reassembled your slide lock lever, make sure the spring rests under the top (locking block) pin. Just put the top pin in before putting in the lever and lower pin. This should solve your problem.

If it were a 1911 pattern pistol I would ask if you had installed some type of shock buff that is preventing a little rearward movement of the slide. Not sure about them Glocks....tungston guide rod the same dimension as the original??

You're using 10rd magazines? Are they brand new? If so, you may need to break them in through use (only cycling will wear a mag spring, not leaving it loaded) before you'll be able to insert the full mag into the gun with its slide closed and "slingshot" it back to chamber a round. This is because the Klinton mags (as well as the 10rd G30 mags) push the top round so forcibly against the bottom of the slide when full that this makes it difficult to hand cycle the slide from full battery. Try loading the mag with eight or nine rounds until you get the mag fully broken in and you'll probably be able to slingshot it without any problem. If the scope mount or anything else was affecting the slide stop you would experience malfunctions while firing.

I recommend that you consider dropping your race gun's recoil spring weight to an ISMI 13lb spring. This gets the slide speed up during fire, reduces felt recoil and puts no additional wear on the gun. It will also make it easier to cycle by hand with a full mag.

The follower doesn't actuate the slide lock until the last round is fired and the mag is empty.

Take all the aftermarket stuff out, reinstall the factory parts and put everything back together correctly and you will again be able to 'slingshot' your new Glock.
I have a G34 and none of that stuff will make it shoot better.

While I am not fan of ghost rocket connectors (or any connectors other than Glock OEM), I don't think that any of the aforementioned aftermarket parts are red flags in terms of reliability or function. While I don't think that aftermarket parts can make your glock shoot better(only you can do that), they can make it shoot the way that you want it to, and that's no small thing.

I am unclear about Sactown's first post as to whether he is have trouble "slingshotting" from a slide open or a slide closed position with a full mag inserted. If it's the later, I would look to James481's answer, but I don't understand that why the slide isn't locking open during firing with rounds still in the mag.

This is the single most common mistake when reassembling a Glock.

tungsten guide rod,

Try removing the tungsten guide rod and putting in the G-34 plastic captured spring guide rod that came with the gun. That will fix the problem for sure.

Its the guide rod head on the after market rod that is stopping your slide from reaching the full rear position that would allow the slide stop to drop, just like a shok buff will do in some 1911s

We all know this is not what you wanted to hear but.....

Once again, take all that stuff off the Glock and go back to stock. Simple as that.

Glocks really were meant to be used right out of the box. The quickest way to slow one down is to install all kinds of aftermarket parts.

We all like to personalize our stuff and make it something that know one else has. This is not a bad thing most of the time but a Glock is not the platform to do this with.

Hey Sactown. Incoming phone call.

Thanks for the suggestions everyone. I will try breaking in the mags first. My problem is sling shotting the slide with the slide locked back and a fully loaded magazine. I have had no problems while firing and the slide locks back on an empty magazine. This is more my fun gun and not my HD gun so I'm not that worried about having to use the slide lock to release the slide, it's more of an annoyance. Hopefully it's just some breaking in issues, but I'll try everyone's suggestions, 'cept for putting in the stock parts. :D This is my project/goof around gun.

Just another suggestion,

Check to be sure that the mag body or the bullet of the top cartridge in the mag don't interfere with the slide release enough to lift it up and keep the slide locked back. This can easily be seen by inserting a mag into the frame with the slide removed.

....and the winner of the Sactown Can't Put His Glock Back Together Correctly is ....James481. I didn't have the slide lock spring resting under the top pin. :scrutiny: Problem solved, back to shooting fun!!
