Sounds odd but what the Armorer had to say makes sense.

You are absolutely right, TAB. They are the AKs of pistols: they are not the most accurate, pretty, or well made. But they are damn effective.

I really enjoyed one episode on one of MB's competitor's shows where Dave Sevigny (sp?) beat all the 1911 clone and S&W boys at S&W's Winter shoot last year. I really had to chuckle seeing him kick their asses with his ugly, plastic pistol.....

The bad news is the malfunctions occur when shooting weak-handed, strong-handed, or two-handed. The good news is it's only a major malfunction with a .40 caliber Glock, and there are several other guns that could replace it. Aluminum frames that don't bend like plastic when you shoot them only weigh 3-4 ounces more. The best news is that the .40 caliber is like an appendix - nobody knows what they're good for and we can all live without them.  ;D

The 40 just can't get any respect can it?  ;D

For me, I shoot 9mm or 45 ACP. There was something about the 40 I just didn't like. Evidently, there are many who feel the same but are much more articulate about why.

Anything the .40 Short&Weak can do, the .45 does with a lot less chamber pressure and a fatter, heavier bullet. If you want something smaller get a 9mm and you don't have to put up with the recoil of the .40. JMNSHO.

My understanding of the .40 origins was that it is a smaller version of the 10 mm. Some police departments were going to the 10 but some of the decision makers in those departments objected to the recoil of the 10; so the .40 was created. I don't know if it that is true but it sounded plausible....  :-\

The recoil of the awesome 10MM was too much for America's Finest so they down-loaded it and called the WEAK version "the FBI load". Since the case capacity wasn't be fully utilized they SHORTened it. That's how the .40 Short&Weak came to be.

I'll stick with my .45 O&R thank you.

OK, I'm ready for the s-storm to follow this. PC to the rescue! The reason for the .40 I was told - most female fed recruits/agents couldn't handle the .45 or the 10mm. So stick everyone with the .40 . I'm surprised they didn't go down to the 9mm, guess there are limits to pissing people off. PA Troopers 'upgraded' to the .40 from the .45 also...

Kinda like male PO candidates here must go over an 8 ft wall unassisted and the females get a 6 foot wall and a step if they need it.  Not to mention the 2 1/4 mile run requirements - a 18-20 something female candidate gets 30 seconds more than I at 47 must run it. WTF? IRL I would be expected to get where I need to be - when I needed to be - partner-less because of PC???

The FBI started out with a .45. It kicked a little bit so they switched to a 9mm. Agents got shot and killed by people they already shot with their 9mm, so they switched to 10mm. It kicked worse than the .45 so they down-loaded it. Then they switched to the .40 that is nearly equal in performacne to the the .45 they started out with, but supposedly has a much sharper recoil impulse. Then special units switched to the .45. WTF?  ???  Why didn't they just stay with the .45 that they already had instead of going the other route, .45, 9mm, 10mm, 10mm "lite", .40, and back to .45?

Alright the .40 bashing is making me sad :-[.    I like my .40's. My first was a S&W model 411. 

Here's a 2002 AG article re: 9mm, 40, and the 45ACP. With a funny title.

http://findarticles.com/p/articles/mi_m0BTT/is_158_26/ai_86704766


The .40 S&W cartridge has become a huge success in the United States because, while possessing nearly identical accuracy[10], drift and drop, it adds 50% more energy over the 9 mm Parabellum with a more manageable recoil than the 10 mm Auto cartridge. In the rest of the world it has become a popular combat pistol shooting sports cartridge.[citation needed] With good JHP bullets in the more energetic loads (> 500 ft·lbf) the .40 S&W can create hydrostatic shock in human-sized living targets.[11]
.40 S&W Load Tables

The energy of the .40 S&W exceeds all standard-pressure and +P 9x19mm Parabellum loadings and many standard-pressure .45 ACP rounds, generating between 450 and 600 foot-pounds (550 J and 800 J) of energy, depending on bullet weight, with mid to high 500 foot-pounds typical. Both the .40 S&W and the 9 mm Parabellum operate at a 35,000 psi (240 MPa) SAAMI maximum, compared to a 21,000 psi (150 MPa) maximum for .45 ACP[12]. Some small ammunition manufacturers offer .40 S&W ammunition consistently developing energy well above 500 ft·lbf (700 J) in all their .40 S&W ammo as off-the-shelf items.[13]. While SAAMI has not established a +P standard for the .40 S&W, there are companies marketing ammunition claimed to be +P, but they do not provide pressure data to support +P labeling.

Good shot placement is more important than caliber.. But I enjoy my FN9 also, BUT, IMHO there is only one .45! ;)

Personally the 40s I have shot recoil worse than a 45.  40s seem to be very 'snappy' to me.

Sorry if I seemed to be giving no love to the .40 .  I've no problem with any particular weapon (unless it shoots backwards), but like most folks, I have my preferences. I'm really giving no love to the PC attitudes that frankly, may get people unnecessarily killed. As I've found out, the best performer is the platform you are comfortable with.

And after looking at the info on the tac light and the glock, I'm even more in line with letting LE qualify with what they are comfortable with.

I'm pretty sure we could give dave just about any hand gun and he would still kick ass.  His glock are about as stock as a nascar...

About Dave: I agree with you about his skill....I think he shoots production in USPSA and I think they are very limited in what they can do in that division; disclaimer- I have never shot USPSA so I could be wrong about what is allowed in Production.

I understood where you were coming from: I just like them- I must because one of them saved my life about three years ago.....

In the end, I think it's all about preference no matter what one decides to shoot.

Production = you can do what ever you want to the inside of the gun as long as the out side stays the same other then sites.  At the very least i know he as a trigger job and diffrent springs.

I personally will not carry a 9mm for personal use. I have to use it when I am doing work and have seen it fail at stopping my aggressor. I use a .40cal Taurus and love it and the round. I have owned 40 Rugers and loved them too. I just can't bring myself to carry a 9mm. I do however want a subcompact 1911. I do love my 45's. =)

It occured to me that having a light on the gun instead of in your other hand forces you to sweep your muzzle across everyone before you identify them as family, friend, or foe. I don't like people pointing guns at me.

As to the .40 vs. 45 issue, .45 ACP cases were made with a large capactity to hold the bulky powder of a century ago. With modern powders you can fill them way up before they get to .40 S&W pressure levels. And if you load regular .45 bullets in suitably strong cases to about the same pressure levels as a .40 caliber you can get over 800 ft/lbs ME and have .44 Magnum performance in a M1911.

Well....  once again I disagree with this hooplah..about Glock's and tatical lights. Is there something to it? Really? Is it a certain type of light?...  I dunno. I do know that I've shot my G23 (that's right .40 cal) with the standard Glock tatical light well over 1500rds without a single jam, malfunction or hi-cup. Maybe I'm the only one in America that has Glocks that work like they are suppost to. I dunno..  I shoot my G23 and my G27 a lot and amazing they run flawlessly. And as far as recoil.. at least out of polymer .45's, like the H&K for example, the .40 ain't any worse. I'll try to do even more research and evaluation with my tatical light or others if I can get more ammo.. after trying to buy everything I can before BHO gets started  :(. And the only other thing that comes to mind would be if someone was shooting some of the very first Glocks to have lightrails cut in them. Perhaps,  they were cut at a time before the deminsions of what most light companys are using now. Even though I have shot the crap out of all my Glocks (yes mostly .40's too) they are mostly all the newer.. Glock models.. only 2-4 years old.

yes we know, glocks are perfect.   ::)   the thread I got that link form has several other links in it( its on THR, should not be hard to find), all reporting simlar probs and from all over the place.  Including glock forums.   So i'd say there is something going on with them.  It could be something like  how the wieght of the light changes the balance point and its a grip  issuse, then again it could be frame issue.  it does not really matter what is cuasing it, just that it is happening.

Tab, maybe you are right. But, I can assure you that my Glocks have not have any issues thus far. And I know of a few police officers and military people that have used tatical lights mounted to their Glocks while they were shooting them. Fortunately, they survived because their Glocks did work while the tatical light was attached. Maybe they got lucky too. I dunno. But, I appreciate your willingness to report any issue what so ever if it pertains to Glock. Keep up the good work.  ::) And the next time I go gun shopping ... I'll buy a Glock just for you, only I'll keep it because I know the truth. Dang that coolaid tastes good!  :P

I've never had any failure to feed with or without a light on my 22. I've had my own personal failure to insert the magazine properly during competition a couple of times, but that was all on me. I don't know if these people are having a problem that is a design flaw or a user error, but it seems that the design of the rails would somewhat hamper any flexing of the frame that some are stating as necessary.

I also have a 23 that I've had since 92 or 93. It has no rails, but it has eaten a lot (I mean mega-buckets) of ammo and has never had a single problem. I did however recently replace the recoil spring assembly, but only because I wanted to use the captured assembly. That 23 truly is "perfect."

Figures. A quick search on the 10-8 forums tells us that these Glock 22 problems are WELL documented. Apparently Glock hasn't been able to resolve the problem.
Title: Re: glock + tactical light= failure.
Post by: Big Frank on January 08, 2009, 06:57:53 PM
From what I read the problem is mostly with bigger non-Glock lights that people buy because they say the Glock lights are wimpy little pieces of crap. I haven't seen a Glock light next to another brand so I can't compare the size and weight. I wonder why none of my dealers seem to carry the Glock lights? Anyway, if that many Glock owners have a problem then it has to be the gun that's messed up, not the people. The solution is simple. Trade the .40 in for a .45 or 9mm Glock. Problem solved.

Did you read the posts that he linked to ? There were a lot of them but they all seemed to focus on a fairly small number of models. Also, somewhere, either earlier in this thread or in one of those posts a Glock Armorer posted with a reasonable (to me) sounding explanation of what was happening and why and I believe he narrowed it down to a particular range of serial numbers. It does not matter how perfect Gaston's design is or isn't if the guy mixing the plastic was hung over one day.

What were the serial numbers that were mentioned? I haven't had any issues, but I'm curious. I ran the Glocks through a few hundred rounds tonight with no problems. I'll be getting rid of a few Berettas though. More Glocks please!
