Glock Heavy Loads

Springs, springs, springs...

The author explains, “The stock recoil assembly wasn’t designed for the recoil of the heavy 10mm loads. The Glock was built around the 9mm NATO cartridge. They used the same recoil assembly in all the standard frame pistols regardless of caliber. It is over sprung for some and under sprung for others.”

If people are concerned, just get a separate guide rod and heavier spring in the 10mm’s, not a big thing, people do it all the time on 1911’s You also have to take in account, slides are bigger and heavier on the larger calibers, more mass to offset some noticeable recoil

for the uncaptured springs i use a tungsten gr and flatwire spring of whichever # is needed. 1 day i might try the "recoil reducing" setups? some are 2 spring, but many use 3.
 
not a fan of heavy loads in 10, 9 or much any other pistol cartridges. using heavier springs would be the way too go in some loads, but becomes muzzle energy dependant and reliable function.
I still use a G20 standard-strength spring in my Lone Wolf long-slide (6") because the extra slide/barrel lengths weight tames the hot 10mm loads.

Enough to the point where the softer 40 S&W type loads barely make it function.

they are some heavy slides for sure! other than lengths being different in the 20 and 40 the widths stay the same unlike the 21 and 41. good thing is the 20/21/40 use the same holster and the 41 can use the same holsters as the 17/22/31's. that's of course the holster being an open ended type. saves me money!
 
The Glocl 20 slide was over built to compensate for original 10mm Norma velocities. If you noticed the
Glocl 41 has the same slide width as a 9mm slide because the 45 doesn’t have to have the slide mass.

I also will say this as a Hlock armorer that worked and saw a lot of 10mm and 40 call Gkick use red come in with issues.

He biggest issue is people (and agencies) are cheap on replacing recoil spring assemblies. Period.

That’s why 40 cal has so many issues with cracked kicking blocks BUT nobody does proper inspections to find it OR timely RSA replacement to prevent it.

The 10mm is more forgiving because if the massive slide but hih still have to change them ours which over 80% of users do not.

And many will go throw some Spexial aftermarket RSA and think they are good and never change it out and then start having issues.

Everyone can do what they want but the original 10Mm Norma load was about as good as one can expect. If you need more a 44 mag revikver would be a better choice.

As far as “Bear loads” (like most of the ones talking don’t hike in the wilderness area theor waistline tells everyone they don’t)

I just talked to Chuck Haggard and Justin Dyal this weekend. And we all concur a 9mm with 147 grain Flat point TMJ would so wverything with the penitrarion. That load zips through 2 gel blacks (iver 32”) and keeps going

But everyone can do whatever

i realized that the 41 didn't need the mass the 21 did although they same recoil spring is used. yes, those og loads with 200gr needed more poundage to go with the mass on a 20 size.
