    I've briefly searched recent posts, but it's been some time since I was warned not to fire 180 grain bullets out of a .40 S&W Glock.

    Is that general warning still operative?

    Was it intended for only early .40 Glocks?

    Are there any Glock models/generations with factory barrels now considered safe with those loads?

    I'd really like to know. Until told differently, I'm shooting those factory loads only in guns made by other manufacturers.

    Thank you for anything you can tell me on this issue.

    I guess all us competitive shooters that run 40S&W, maybe like 40,000 in USPSA Limited alone, at about 20,000 rounds a year, and all the LEO depts that run 40s, never got that warning. What warning? From Glock? The very first 40's had some brass bulging, that's all. And the very, very first Federal rounds that came out were a little too hot. But all semi autos have what the internet calls "unsupported chamber" which is really the feed ramp. They won't work without it.

    I think the issue with 180s was the pressure spike when rounds are repeatedly rechambered causing bullet setback

    In fact, most guys run a 200 grain 40S&W because it is softer shooting and makes the USPSA Major power floor going only 825 fps. Especially popular in IPSC, where the floor is 175,000 and it still only needs to go 875 fps.

    I carried a G23 for about 15 years, fired 180 gr rounds through it frequently, and never had any issues.

    Chambering the same round, over and over, is not a good idea, for any caliber. First of all you never unload a carry gun, it's always hot. 2nd, when you do get to the range, recycle the chambered round by shooting it out first. It's not like anyone goes thru several hundred rounds of carry ammo a month.

    I’ve been shooting 180 grain almost exclusively in a Glock since 1993. In the Glock 23, I would occasionally get some bulges in the brass. I no longer have the 23 but I have a couple other 40s. I haven’t noticed bulges in the casings in my Glock 27 or my Sig 229 for that matter.

    Thank you all for your encouraging remarks. I'd been doubtful about the case of Remington 180 grain Golden Saber I picked up last week.

    Shoot that Golden Saber stuff, brother Flincher. Its yummy. About 5,000,000 cops have been shooting it or similar 180gr .40 in their G22's for the past 20 years.

    Shoot the hell out of that Remington GS. I have an old Gen2 23 that has at least 2k rounds of 180-gr GS ammo thru it. All without a hiccup

    It is complete internet myth.

    Only a moron buys into totally illogical nonsense.

    I've only been exposed to Glock .40 S&W for 22 years. I heard some grumble many years ago that the 180 grain was a compressed load because of the powder type and bullet length.
    The main knock then was at times inconsistent lots and some accuracy issues.
    I don't recall any pistol issues and all the LEO that use a .40 just love 180 grain. I don't know why and most of them don't either, but it is very widely used. Probably more so than all the other wights combined. I'm sure the issues have been long ago addressed and corrected if there was anything to them.

    Anything from 165 grain to 180 grains is the optimum bullet weight for the 40 S&W. The 40 with 180 grain bullets is comparable to th 45 with 185 grain bullets and even though the bullet diameter of the 40 is just about half way between the 9mm and the 45, ballistically it's closer to the 45 than it is to the 9.

    Years ago when the 40 was first introduced there were a rash of "Ka-booms" on the internet most likely cause by reloaded ammunition and not factory ammunition and people theorized that the G17-G19-G26 platform was inadequate for the 40 S&W.

    But when Glock came out with the 357 Sig built on the same frame there were no disastrous results in spite of the fact that the 357 Sig is loaded to higher pressures than the 40 or even the 10mm.

    A Glock is plenty strong for any 40 S&W load even those made by Double tap, Underwood, and Buffalo Bore. If you were uncertain whether or not there was an "Issue" with any kind of 40 S&W ammo in a Glock, this forum is a good place to get answers to that question

    When I do shoot .40, it's only 180gr on up.

    .357 SIG makes it too much fun though, so I rarely shoot .40 anymore.

    I unload my carry/duty gun on occasion to shoot range ammo. My agency issues me 180 gr HST. As a FYI: I once chambered a round of Golden Saber 50 times. After the 50th rechambering it measured 0.005" shorter. The first 5 rechamberings didn't budge the 1.120" starting length. There was a difference of 0.004" in unfired rounds from the factory, 1.120-1.124" new in box.

    This is a big load of doo doo. I agree with clambering the same round over and over but the rest is way out there. Leave your carry cub hot and never unload it??? Are you for real?

    I'm not sure what you are trying to say, but they work a lot better with BOOLETS in them.

    Seriously?

    Do you REALLY think Glock would be selling a pistol that would be at high risk for "blowing up" when firing generic .40 S&W ammo? The internet has been responsible for a great many negative results including whether or not a person who owns a Glock of ANY caliber, feels comfortable shooting it with factory ammo. Seriously? Do you think Glock would still be in business if they needed YOU to look out for them? Or some other internet "town-cryer" to tell everyone what to do in order to not have a blown up Glock?

    Seriously.....if you don't think the pistol you chose to buy is up to the task then do NOT buy it!
