Looking for a 40# recoil spring for a Glock G29.

Anyone know where I can find such a high rate spring system?

Most of the big name gun spring companies only have 23# max available for this gun.

Thanks,
TW
 
You might have to try an industrial spring supplier, measure the free length and diameter and see if there is a 40# spring that is close in dimensions. Have you asked at the 10mm forum on AR15 armory?

What are you loading to that you need a 40# spring!
 
That strong a spring so far over the factory options implies that you're loading up ammo that is well above the safe limits for 10mm ammo. Not a really good idea given what appears to happen to some Glocks when fed overpower ammo either by accident or design.
 
First of all, if you get a 40# spring the compressed length is likely to be longer then the tunnel, and you're likely to ruin the pistol I suspect that's the reason you're not finding anyone offering them

Second, the Glock is a locked breech, not straight-blowback pistol. The slide only travels a very short distance before the slide and barrel seperate and the slide continues backward. At this point the bullet has left the barrel, and internal pressure dropped to zero.

Third, if you are using anything close to a 40# recoil spring the pistol will quickly beat itself to death when the slide goes back into battery.

Last but not least, you may not be able to pull the slide back to chamber a round. :uhoh:
 
Which, if he's loading rounds above the SAAMI specs so he feels he needs such a thing, may well be a good thing....

With that spring he won't need no gunpowder... :uhoh: :D
 
Is this serious? :confused: You might as well get a a T/C Contender in that caliber and get some more velocity out of the bullet in the bargain, because your pistol is going to be a single-shot anyway. :neener:
 
I'd be interested in something stiffer than the 24# that's out there also. When I shoot my 9x25 conversion on some of the hotter loads the 24# spring doesn't quite cut it and the slide locks back after overtravelling. :what: Then I have to tap the back of the slide with my palm to get it to come back to battery.


So yeah, I'd be interested in a 28 or 30# spring.
 
if the slide is locking back under recoil, what you need is a sharper notch in the slide, and a stronger slide stop spring.

The purpose of the spring is not to absorb recoil, the purpose is to close the slide.
 
Going from 23lb to 28lb seems reasonable. But all the way to 40lb? Let me get behind the blast shield first, please! :uhoh:
 
Seems like the answer is, "no." No one knows where to find such an off-the-charts item.

If the OP wants further discussion on the matter, he can PM me to reopen.
 
Sam - Thank you. I appreciate your point regarding the request for serious answers only.

Obviously, one doesn't need a recoil spring for a T/C encore (I've owned one in the past) and while I can appreciate the humor of duct taping two 20# springs together, that's probably not going to work very well. :D

I apologize for not getting back to this thread earlier.

I have made the request to Wolff for a 40# spring set.

That request was denied.

Then I asked the company if there is any additional rate they could increase the spring.

I explained to them that if you load the 10mm cartridge near or at the 37,5kpsi current SAAMI spec, the 23# spring set in the G29 is still insufficiently sprung to reduce recoil enough to the point where the cartridge casing is spent within a reasonable distance of the shooter.

Their reply was that they simply have no plans to produce a high rate spring for this pistol.

I respect their decision to limit the production of such springs, as I'm sure there are several reasons they should choose that decision - none of which have to to do with actual safety, but some of which could be associated with a safety "theater" of sorts (The main actors being irresponsible people and attorneys).

Despite my thoughts on the reasons, I have been unable to find what I am looking for.

THR acquires a great deal of traffic - some of which include intelligent, knowledgeable people. If one of you should have information on an advanced spring concept (particularly a design that has variable rate springs associated with it), I would appreciate a response to this thread or via private messaging.

Thank you.

In pre-OTC springs' days, an excellent gunsmith would have been able to make one. The idea of softening felt recoil is not new.

Nowadays, for liability reasons, it might be harder to obtain. Unless you are kosher with an excellent gunsmith.

So this is my idea. Contact a spring manufacturing shop. This is the catch, if you tell them that it's for a pistol they might refuse. So to order one you would have to provide them with the exact specs that you want. Length, width, whatever.
 
If all your looking for is to find your brass closer and not go beyound what spring rate is needed that can be done. Start to file down your ejector till your brass falls where you need it to. I had a witness that could trow brass 25 feet under a roof. I filed about a 10th off and brass fell about 12 feet a bit more and they were at 8 feet. See how your pistol works with the 23lb wolf springs first and then start trimming the ejector. just changeing to a 40lb spring may stop your gun from cycling and beat your pistol to death when closeing

This may work. And if you go to far you just replace the extractor...
 
Guys, limiting the distance the brass eject is NOT the primary purpose of going with a higher rate spring. The primary purpose is to absorb recoil of the SERIOUS rounds I will be firing in this pistol - think along the lines of the .460 Rowland.

It's not .460 Rowland, but it will certainly have about the same foot pounds of energy as the Rowland (more or less), and also about the same recoil energy - only the barrel (not a 10mm barrel, but an aftermarket conversion barrel - which will actually arrive in about 3-4 days) will not be ported, extended, or compensated.


The 40# rate is a "guesstimate", as I would like to see what's available first before machining a spring set and bar myself.

Actually, even if someone has an idea to get a 28# spring, that would be just about sufficient for the loads I am running through my G29 (KKM barrel) right now, which are very near or at 37.5kpsi - not sure if any of you have shot Swamp fox 200gr. XTPs, but my loads are approximately the same velocity (~1230 fps average out of a 4.5" bbl.).

The new chambering (not going to disclose this cartridge for my own reasons) will be targeted to push a 200 gr. bullet at approximately 1500-1600 fps using the stock length (3.8") barrel.

This should make it good to go for hunting big game.

This will not be a "single shot pistol" as the recoil spring I desire should closely match the recoil energy of the newer cartridge. I would not expect such a spring to allow the slide to eject in its 10mm format however...
 
Well good luck. 10mm has a 37,5500 working limit already and pushing that from 200 gr at 1200 fps to 1500+ hope you have a strain gauge on a test barrel first and then a remote pistol rest for yesting the glock. Good luck. Should be looking to a double spring setup.
