Is 357 SIG too much for a Glock?

  1. I know that this is is sacralige, but I have a question.

    I have a glock 32 and have about 10,000 rounds through it. I have cracked a slide, broken a trigger hinge pin and broken the disasembly lever spring. Compared to my friends 9mm glocks, that is a lot of problems. Glock did right by me, but I am starting to wonder whether there is a much shorter service life with this caliber. I hear that it is definately banging up sig pistols quicker.

    Thoughts?
     
  2. Just wondering did you by chance use a stronger recoil spring to try and dampen some of the recoil? What kind of loads do you usually shoot?
     
  3. Damien,

    I'll have to agree with Reflex regarding the ammunition. Are you using hot reloads or factory manufactured ammunition? The Glock in my Avatar is a G22 that was manufactured back in 91 it now has a KKM 357 SIG barrel and I originally fired over +25K (175PF) 40 S&W and over 10K(+6k 140PF -- +4K 173PF) 357 SIG and no problems to date. BTW the only things that have been done to the gun has been to replace the original adjustable sights with Trijicons, replaced the magazine release with a JP Enterprise magazine release, DMW Trigger Job and inserted a Seattle Slug. This gun actually reminds me of the Eveready Bunny...
     
  4. Standard recoil spring. Factory ammo only. Usual assortment of Lawmen, Blazer, PMC and Golddots.

    DOn't get me wrong. I still love my 32 but I am wondering how long she is going to live. The only failure that caused a malfunction was the disassembly widget breaking. The slide flew off the front of the gun. Serious malfunction with no tactical fix I am aware of.

    ;)
     
  5. You could probably extend the life a little by putting in a heavier recoil spring.

    ryucasta- are you saying that your shooting 357 sig with a non reinforced frame? What kind of recoil rod/spring do you use?
     
  6. Reflex,

    I'm still using the original Glock Guide rod/Spring that came with the gun back in 91. Mind you I do carry spare factory guide rods and springs and I also have a Stainless Guide Rod and a 20 pound spring but to date no problems after firing over +35K in assorted PF rounds.
     
  7. Im using an uncaptured 22lb Wolff spring in my G32.
    Works just fine.
    For what it is worth..................WEB
     
  8. I have a 22lb ISMI recoil spring in my 31. The slide speed is slower than with the stock spring. I think most of your problems are related to the front cocking serations you had cut into your first slide. You lowered the mass of the slide without adding spring weight. Or not
     
  9. You might be on to something... glocks handle 10 mm better than most, but that is with the even stronger and larger frame. I would change out the mainspring to a 22 lb captured stainless unit. The spring helps and the bit of added weight from the stainless rod helps too. The compensated version would bleed off a bit of speed and wear as well. I think glock will stand behind your gun , so it is a matter of convienance . Try another 10000 rounds and get back to us... with the carnage...
     
  10. A easy fix to those reliable problems might be a g20/29 with a conversion barrel. I figure the bigger thicker slide would hold up more than any G31/32/33 slide.

    {The slide flew off the front of the gun.}


    I still don't see how the slide just flew off the front of the gun? A broken or missing disassembly spring would just allow the slide to move but not fly off the gun if you try to pull the trigger. You are correct that if that spring or locking tab is broken or missing you are up a creek without a paddle and a canoe with no easy fix. I started carry one of them along with the trigger reset spring.
     
  11. Interesting theory on the cocking serrations. The last several thousand rounds have gone through a stock slide.

    So what recoil spring should I use??

    THanks,
     
  12. My G-33 has the Wolff recoil reduction kit with 22lb spring. It's ported......only problem I continue to have is keeping the metal front sight from coming loose. I guess I need to go to Gorilla Loc-tite. The G-33 has been rock solid with many rounds thru it. It handles all my reloads just fine. Ya know the operating pressure of the 357SIG is 40,000PSI........a .40S&W is 35,000PSI We're just high pressure kind of folks and sometimes things go south.....just my humble opinion. I just love this caliber, fun to shoot, fun to reload, fun to go BANG!;6
     
  13. 40000 psi is high pressure. For comparison sake... what is the pressure of 9mm and 45 acp which is way lower...
     
  14. 9mm = 35K
    9+P = 38.5K
    9+p+ =anythingover42K,unregulated,no imits
    10mm = 37.5k
    45ACP = earlier specs 18K , raised to 21K
    45ACP +p = 23K (IIRC)


    So yes a 357sig is high pressure when compared to SOME other calibers. But it's isn't when compared to rilfe caliber and other calibers like the 454casul and 480. These other calibers easily runs into the 50K+ range.

    I also find it strange when people tag the 40S&W a high pressure round. It's "max" operating pressure is the same as a 9mm std loading.
     
  15. Last night I went through about 200 rounds of Blazer and Lawmen. The trigger hinge pin broke AGAIN!!!! Less then 1000 factory rounds on this pin. What gives?

    For the record, the gun kept working, but still...


    Any thoughts?

  16. Damien,

    The max pressure for the 357 SIG is around 45K which is about 10K higher than 40S&W or standard 9x19 loads. It strikes me as odd that your having this problem since the model you have was originally chambered for 357SIG caliber unlike the ones I have which are all conversions. If I was in your shoes I would be contacting Glock and have them give you a new gun since it seems like you have a lemon. Since your located in California, if you still don’t get satisfaction I would take them to small claims court since the dollar amount in question is less than 5k and this is a case you’ll easily win. Anyway that’s my 2 cents.
     
  17. Actually, I moved back to America. I am in Washington State now.


    Very weird, to have had these issues all of a sudden. I had come to trust this piece with my life (in fact it saved it once), and now I have doubts creeping in...

    D
     
  18. ryucosta is dead on right. take his advice & call GLOCK or have the pistol checked by a Glock Armorer. Your pistol should not fail like that......mine has been stone reliable and it is highly modified....best wishes and keep us advised how this turns out for you.:(
     
  19. No
     
  20. Where in Washington? I am amazed at your ability to break the Trigger Pin with such regularity...I have replaced many broken trigger springs but never a trigger pin. -Coug (Glock Certified Armorer)
     
  21. Coug- My wife (armorer) said the same thing. She's never done an R&R on pin. I would advise our friend that this pistol with such a history qualifies as a "not safe to shoot" until this issue is remedied. I wonder what else might be burned, bent, broken & ready to fail.?
     
  22. Hello Again,

    I live in the Seattle Area and am taking my 32 to the GSSF match this weekend. The folks at Glock think it my be the locking block. They asked me to have the armorer look at it and if necessary, send it to them. They are sending me some trigger pins in the mail.

    The first time I did it was at John Farnum's course. He carries a 32 as well and had never seen/heard of this issue before.

    D
     
  23. By the way, I am not a certified armororer but I have worked on Glocks for years and everything else seems to be as it should be. I have not had an oppurtunity to look at the block yet.

    D
     
  24. I recently inspected a fellow shooter's GLOCK at an IDPA match after he was getting erractic operation. I found a crack on the left lateral side of the locking block.He was using an aftermarket metal guide rod & uncaptured spring. In addition to a crack in the frame a small chunk of metal was gone from the front of the block. his was a 40S&W. The guys will take care of you at the GSSF match. We sent the broken block back and he got a whole new lower.......Good Luck and let us know how your problem was resolved.
     
  25. As long as you get it looked at you should be fine. I just moved over to the dark side of the state (near Bothell). My first thought was an out of spec locking block. Anyway good luck with your gun. It sounds like something very wrong is happening with it. I wouldn't put it past Glock to replace the receiver if there isn't anything obviously wrong with your re-assembly. Just make sure that it's put together correctly before you take it to the GSSF match. If its wrong you may have to wait until it breaks again before they replace it (but I doubt it). Heck if there is a real problem they may be able to swap it at the match (I have no knowledge if they can or not, wouldn't it be nice). -Coug
     
  26. The saga of the sick 32 has ended!
    At the GSSF match in Shelton WA, the armorer disassembled my Glock and the locking block came out in 2 pieces. Hmmmm… It certainly was not broken when the first pin broke, but it finally gave up the ghost. It is a credit to the gun that it functioned )albeit roughly, with a broken locking block and trigger pin. The armorers replaced all the springs and pins in my 32 and my 35 (6 inch barsto barrel), and changed the trigger in my 35. Much better now. They also changed the followers and springs in all my mags. All was done free of charge. GSSF is a great program.

    They were also selling preban, nonmetal lined bright orange training mags. They are ugly but they work great.

    Thanks for all the input.
     
  27. Went to the GSSF matchi in Shelton WA and turned by 35 (6 inch barsto) and my sick 32 over them. I had not dissasembled the 32 since the second pin broke. When they removed the pins the locking block fell out in two pieces. They replaced all the pins,recoil springs and extractors in both guns. They upgraded all the followers and springs in my carry mags and armorer cleaned both weapons. All for free. Got to love GSSF.

    Interestingly, they also were selling new, preban, non metal lined, bright orange training mags for Glock 23's. They are ugly but they work!!

    Thanks for all the imput. My 32 is back and all is well with the world.
