someone posted about the EAA witness 10mm needing a stronger spring when using dbbl tap hot loads and still not being reliable. Would the glock 10 mils need the same or are they good to go out of the box?
would the g20 or g29 need a stronger spring?

Glocks are pretty tough. Just decide for yourself. I shoot a bare-bones Glock 20 with hot DT's and have had no problems whatsoever.

Howdy Capitolpeak, and et al.,
My G20 has got a few miles on it, 2.5k+ (quite a bit more if you count all the 40SW through my conversion barrel), stock recoil springs. While I'm not running DT ammo, I principally run factory rounds (180 grs at moderate levels) with a small percentage of reloads. I'm still running the original spring but I've got a spare ready to go when it doesn't pass the vertical lockup test. I've found that all my Glock patterns hold up pretty well. I don't go through too many parts as they seem to hold up well. Even though, just as all things mechanical it does pay to keep reasonably close eye on things to keep em running well.
Cheers!

The Glock 10mm pistols (model 20 and 29) are fine as they come from the factory and they do not 'need' a stronger spring. A stock Glock 20 or 29 is reliable and perfectly safe to use with any factory ammo (be it mild practice ammo or full house loads), or any shooter reloaded ammo that is within the pressure specs for the 10mm cartridge (though like most manufacturers, Glock officially states their warranty is void if reloaded ammo is used with their pistols).
Now having said that, when shooting full power 10mm ammo in any 10mm pistol, sometimes the extreme velocity spread can be higher than typical, and a stronger recoil spring will reduce this spread. Buffalo Bore has an excellent explanation about this on their website (see the bottom part of their 10mm ammo section).

Again the Glock 20 and 29 are reliable and perfectly safe with full power 10mm ammo as they come from the factory, and the sole advantage of a heavier recoil spring would be a reduction in the extreme velocity spread with some full power loads.

sonic---- thanks alot. interesting stuff on BB. I didnt know it wouldnt affect the function of the gun. I thought it would like jamb or something.

The G29 is a fantastic sidearm. Mine is totally stock and that's the way I'll keep it. My carry ammo for it is Georgia Arms G10B 180-gr Gold Dot that chrono's at 1185-fps from the G29s short barrel. That's 35-fps faster than the published velocity!
I think a Glock 29 and this ammo it's as close to perfect as I can find for my CCW needs.

If it ain't broke, don't fix it! My EAA 10mm was a Jam-o-matic with the factory recoil and magazine springs. Stronger of each has got it reliable enough to be fun at the range, the jury is still out as to if I can get it reliable enough for serious usage.

Well my main ammo would be the full house double tap 230gr hardcast load(woods carry) I have an xd45 for anything less. But Im not sure if those are any more pressure than your 180 gold dots.

Need? Nope. Want? That depends on each unique individual preference. Therefore, there's no answer anyone else can give you on that subject, but yourself, when you fire the G20 and/or G29 with DoubleTap ammo in it.
In general, if you mean 'will the Glocks handle the DT ammo without breaking?' Answer: Easily. Glock 10mm platforms were specifically made for "hot" 10mm shooting. Don't worry about it.
As another said above: Stick to factory ammo, and you'll be okay. Yes, there're reports of people shooting over ten thousand REloaded (their own) ammo through Glocks without one single problem, but that still doesn't make it safe. Only a professional, or one VERY experienced in knowing how to load their own rounds can consistently get away with this.
If you're a newb reloader, then please, do stick to factory rounds!
And if you have to, then load your own rounds very light! With NEW brass! Use an aftermarket barrel, too, if you can.
For defense, leave the Glock stock (except for changing sights to night sights, if you want), use factory rounds, and you'll be okay!
If using reloads, then use 'em for practice only, with aftermarket (LWD or Bar-Sto) barrel inside.
P.S. Stay clear of using lead rounds. Only use jacketed rounds for shooting through stock Glock barrels. JHP for defense against humans, and FMJ for practice, defense against bears, and hunting for medium to big game (if pistol hunting is allowed where you live; look up your local laws to see!).

I don't think you NEED a different recoil spring unless you are going with nuclear loads in the G20 (I have never used a G29). I have never shot a factory round of 10mm through mine.
Reloading for them isn't an issue though. As with all things work up your load and you will be fine. Here is my current load
12.0gr of Blue Dot
Hornady 155gr XTP
Winchester WLP primers
Starline brass
It produces a nice snappy recoil that isn't punishing. I could go much higher but I don't see a need to. I also put a Storm Lake barrel in since I don't like Glock smilies on my brass.
As an aside I also changed the barrel to a Storm Lake in my G23 which I carry daily since again I want to take it easy on my brass. I have shot it a BUNCH and I have no concerns over reliability. If you end up using it changing barrels will be the least of your concerns imho.

As with the general consensus, the Glocks don't need stronger recoil springs, and in some cases, they may not even be advantageous.
However, if you handload, you may find having you brass launched into low orbit to be tiresome. I put a 22# ISMI spring in my Glock 20 when I started shooting Double Tap and my own handloads out of it. The spring keeps the brass on this planet, and to me, makes the pistol feel a little smoother in operation.
Keep in mind that a heavier spring will increase muzzle flip and slow down slide velocity. Competition shooters use reduced power springs for this reason. However, I am not shooting competition, and the heavier spring makes it easier for me to track the front sight, even though the front sight moves a little more.
