I'm not a Glock guy (don't own one, don't have any interest in owning one), but I happen to know and very much respect the guy who made this video about how often he replaces various parts on his competition Glocks.

For anyone who runs high round counts on Glocks, this may be of interest. I think it's clear, well-organized, and analytical without going off into theoretical atmospherics.

 
Thanks for the video. I'm not a Glock guy either, but I was surprised by a couple of things.

I his comments are accurate, I had no idea a broken mag release spring, first could not be accessible, and second could essentially make the frame useless. Big surprise.

I was also surprised, and I'm not completely sure I understood it, but he replaces the mag springs in his 9mm Glocks with mag springs for a .40 S&W Glock.

are they different?? That’s a surprise. I assume the .40 is a heavier gauge?
 
CW among most competition shooters is that guns typically come oversprung on recoil springs and undersprung on magazines.

A stack of .40 ammo is a lot heavier than a stack of 9mm ammo... stands to reason that the .40 might have a heavier/stronger mag spring.

My personal view is that I want as much magazine spring as I can cram in the mag without binding or cutting capacity. A mag spring can be "late" in presenting a round in the feeding cycle (which leads to jams), but I'm not sure it can realistically be too "early." Seems like the only risk would be too much drag on the bottom of the slide as it cycles to the rear.

I misread the above. I read “magazine catch spring”.
 
Is 17rounds of 9mm heavier than 15 rounds of 40 S&W? I ordered some mag springs once and I they were the same part number for the g17 and g22.

Edit: Weighed Gold Dots;
17 rounds 9mm = 208 grams

15 rounds 40 = 235 grams.

But uses same spring

Informative, accessible information, no talking-down and.... NO IDIOTIC INTRO OR SOUNDTRACK!

I like it. I wish more information video producers would take note.

Hey, wait.... Did this fella just video document Glock imPerfection? :evil::neener:

Maybe there are other springs available but these cover most full length grip magazines.

Sounds like some parts aren't "stock" and he's not using full power loads.

It also sounds like he's being a little over cautious in his replacement schedule.

This past summer, after 10 years of weekly shooting with my one 17, at least 300 rounds a week(150k +/-), I finally had something "important" (a rail in the frame) go. The only other parts to go, were two trigger return springs, one at around 90k, and the other at around 120k. I changed the RSA twice a year.

That's it. Gun was "stock", and ammo was mostly my "full power" 124 grain reloads, with around a case or so of +p+ each year as well.

Glock rebuilt the gun, 9 years out of warranty, with the frame stippled to boot (I guess Glock didn't hear that would void the warranty :)), and it didn't cost me a cent. I'm still shooting it every week too. Well, what's left of it. :)

May not be perfection, but it works for me. :D
 
Oops, he missed the Striker Channel Liner...or maybe he's unaware of it. It's plastic so I replace it every 2K rounds (requires special tool). He didn't mention the Firing Pin Spacer Sleeve either, which has metal-to-plastic contact. With a sub 3 lb. trigger, my main concern is light primer strikes...not broken springs.

Not to one up you but as far as warranty with Glock, I don't think time matters. My sister gave me a gen 2 Glock 19 from 1989. The frame was cracked and Glock replaced it 25 yrs. later for me free. Can't complain about CS with Glock.I was amazed it was free and everything was replaced except for the slide and barrel.I love the gun now that it shoots straight.

That spring isn't just for the G22. Glock also uses this spring in the G17+2 or any of the 19 round magazines. So he's probably running an extended mag.
I prefer Wolff but that's just me.

I was really surprised to find they only had a one year warranty. Not that they seem to worry about it.

And youre right, their CS was great to deal with, and turn around was quick. .
 
Shhhhhh. Don't tell him I've had 2 G23 mags loaded since 1999. No spring change and work just fine.

Good info. Thanks for posting.

Honestly, although Tyler is unusually bright, well-organized in his thinking, and very articulate, that kind of detachment from emotional hangups about gear is very common in USPSA. High-level competitors, such as Tyler, are going to shoot stuff so much that it breaks. All guns will have stuff that breaks when shooting the kind of volume that nationally-competitive GM-level guys shoot. Rather than getting upset about it, they just figure out what are the components in a particular gun (or other gear) that break, and they figure out how to deal with that. Usually through preventative maintenance, or sometimes through changing parts, or some other approach.

Among less-analytical shooters, the prevailing attitude is that gun stuff breaking represents a "failure" that they need to yell about. Mainly because their sample size (volume of shooting) is so small that they can't see any pattern - the breakages seem random to them, and like a thing that "shouldn't ever happen."

Shooting high volumes in a measured, competitive context forces realistic, rational thinking on you. It's one of the reasons I like competitive shooting and competitive shooters.
