    Folks,

    I bought my first Glock, a Gen2 G19, in December 1996. Up until that time, my only handgun was a Ruger KP95DC. The Ruger has a very soft recoil spring and will run on anything. My brand new G19 would not run on my light Ruger reloads, range reloads or Carroll factory reloads. I was about to give up on it and told my dealer, Blue Ridge Outdoors, about the problem. The dealer gave me a box of Blazer 124-gr FMJ ammo and suggested I give the Glock another try. WOW, 100% function, but all my shots were low/left--that's another story.

    I had been reloading the lightest 115-gr reloads found in the manuals, so I switched to maximum loads, which functioned 100% in the Glock. Range reloads and Carroll reloads never would work in my Gen2.

    Fact: New Glock recoil springs will soften up after a few hundred normal rounds. My Gen2 G19 now functions 100% with my very light 147-gr reloads, or did until I finally replaced the recoil spring assembly after 75,000 rounds. Now it's time for another few hundred rounds of Blazer 124-gr ammo before Saturday's GSSF match in Oxford, NC.

    A new Gen3 G17, G17L and G34 would not function with my 147-gr reloads at first, but all were flawless after a few hundred rounds of 124's. My new Gen4 G19 has been flawless with 124-gr and 147-gr factory ammo, even flawless with Winchester USA 115-gr ammo

    Glocks do not need to be broken in to function with full power service ammo, but there are some substandard choices out there that may require a short break-in period with a new Gen4.

    I know that we all need to price shop for ammo, but there are many choices within anyone's price range. If in doubt, buy Winchester USA 115-gr or any 124-gr/147-gr ammo.

    And for the dedicated shoppers that think their Glocks should run on anything, don't ever buy a BMW

    You could have just said: "mouse-fart reloads require a softer recoil spring."

    or buy a SIG or HK and feed it all the mouse fart loads you want without issue.

    The only experience that counts is one's own.

    My G3 19 has cycled everything flawlessly. Outside of maybe 20 gold dots, it's been run on the cheapest ammo you can find.

    Now, my CZ P-01 ran 100% on Tula 9mm ammo which is the weakest 9mm ammo I have ever fired. It makes the walmart federal 9mm feel like full power stuff, a true "bunny fart" load if I ever shot one.

    So in conclusion, yes I understand that Glocks require a certain amount of energy to reliably cycle the slide. I see it more of an annoyance than an "issue" per se. And since I know my G3 will be 100% reliable with cheap walmart ammo, I would be dissapointed with the G4 not doing the same. 9mm recoil is light enough to begin with that I don't want a heavier spring if it means lower reliability.

    +1 on that, Danny. You might not have given any new info to the old-boy network, but there's lots of Glock short-timers who are glad to hear that their new baby will eventually recover, and who appreciate your continued help.

    As always Danny your info is right and very appreciated, thank you for sharing and keep on doing it.
    I cannot be more happy with my G19, for me is the perfect gun.
    I can live now only with a G19 an a G26.
    Thank you.

    A sample of one gun working or not is not significant in a % approach.
    If you are an owner of one that does not work, it is a deal for that person.

    That's definitely not true as a browse of the dedicated Sig and HK forums will quickly reveal.

    Exactly. If my G4 19 ever misses a beat and I suspect the spring I will be on the phone with Glock in 5 seconds. But after 700 problem-free rounds I'm not anticipating having to do that. :) I may have them send me the spring anyway, just for spare purposes. It would also be interesting to see if I can tell any difference in recoil or slide racking.

    My Gen 3 G19 OD has had no problems.
    Must be better than black 4th Gen G19s.


    Silly is that not?


    Guess throwing rocks at 1911s, M&Ps, etc. is not such a good idea now.

    Thanks for the info. i appreciate all you put into it. THe Blue i put for reasons.
    One i have 2 Ruger's like yours. Go to the CZ forum and you will find a sticky of breaking some CZ's ie. SP-01 among others( NATO Guns) with basically all you keep so politely saying. I would love to come meet you and others at Sat.'s Match its my daughters Birthday, I'll see how far i'm in SC. Third i worked at BMW and know 100's who still do.

    BMW's require High Octane Fuel for High Combustion Engines. Lastly never used HK for customer service but had a nightmare with SIG's CS on a couple Navy 226's that were the worst guns i ever owned Period. Have a great Match DannyR. I will look forward to see how you enjoy NC and the Match.

    I had similar problems with some underpowered 9mm reloads in my Gen 3 G19 and 5" 9mm 1911. They were accurate and would cycle the gun but not enough to lock back the slide on the last round. I added an extra 0.2 grains of titegroup to my next batch and have not had any problems.

    My Gen2 and Gen3 G19 would cycle my light reloads my G26 will not. Replaced my G19s with the G17; same deal.

    Recoil spring weight is critical. You can have the same issues in a 1911 when you replace the old/used recoil spring with a new/heavier one if you've watered down your reloads to the minimum that would cycle with the old/used spring.

    IMO the issue many have with the Gen4, and understandably so, is comparing it to the Gen3 in terms if ammo reliability. If the Gen3 eats something the Gen4 chokes on, folks aren't happy. I get that.

    The solution to the Gen4 appears to be the use of warm-hot loads. Maybe just in the beginning until the spring wears in, maybe for the life of the gun. That means the cheap target stuff may not run reliably in the Gen4; not great if your goal is to pinch pennies. Defensive ammo is all loaded pretty hot, so no worries there.
