I just shot an IPSC match today with my trusty 34. When tactical loading one in the chamber and 10 in the mag my glock was double feeding for the first shot. Not sure what to look for. Suggestions...ammo, mags, extractor or ejector. TAzz
 
Having not experienced such, what does a double feed entail? Two rounds out of the magazine I suppose, but how?

Ammo, would only be powerful enough to cycle, or not powerful enough to cycle. Even the most overloaded charge, assuming it didn't blow up the pistola, would only cycle to the next round, with only eventually peening occurrring if used constantly.

Magazines, I think.
Weapon Magazines

Magazines are the single most critical component of the weapons system; a properly designed and fabricated magazine can enhance a weapons reliability dramatically whereas a poor magazine can make it non functional. After using modern small arms on nearly a daily basis for over 20 years and having first hand knowledge of what it takes to make a reliable magazine I have come up with some key things to live by;

1.) Baby them. Treat your magazines as gently as you can within the realm of realistic training. Don’t drop them fully loaded during a mag reload drill as that is very abusive and does not reflect reality. Don’t drop them on hard surfaces such as concrete and gravel as a matter of habit. If it is necessary to do this due to range restrictions then put down something to cushion the dropped magazine.

2.) On tough to seat mags, download at least 1 round. If a fully loaded mag is difficult to seat with the slide or bolt assembly in battery then download the mag by at least 1 round as a matter of habit. USGI aluminum M16 magazines are a good example of this as they are really only properly designed to take 28 rounds, not 30 as advertised. Glock pistol mags as a general rule should always be downloaded 1 round as a fully loaded mag is difficult to seat with the slide forward.

3.) Leave loaded only when necessary and rotate with fresh magazines monthly. This will increase the longevity of your magazines.

4.) Attempt to keep them clean particularly in sandy and salt water environments. Do not oil the magazine internals as this tends to attract debris.

5.) Use OEM mags as a general rule. Original manufacturer mags tend to be the best choice across the board. An exception would be magazines for 1911 and AR15 magazines. 1911 manufacturers as a general rule supply a cheap low bid magazine with their pistols as they realize most serious shooters will buy higher quality aftermarket magazines. Wilson 1911 magazines are some of the finest on the market. For the AR, Magpul magazines are worth a hard look.

6.) They require periodic replacement. I know this will come as a shocker for some of you but believe it or not after awhile you need to trash your mags and buy new ones if they are used a lot. They take a lot of abuse and are expected to work 100% of the time with no exceptions yet be reasonably priced. This is a tall order and it means that after awhile they have simply have met their service life and need to be replaced. I know it is a radical concept for some people but it is the truth.

I have lived by these guidelines for years and have had exceptionally good luck with my magazines. Those who know me also know my weapons tend to work very reliably and a major reason is I treat my magazines with the respect they deserve. I would recommend you do the same.

a double feed is a magazine related issue.... since the ejector is fixed in the glock pistol it would have zero impact on how the gun fed.
 
maybe your magazine lips dont have enough friction to hold the round in place when its full (and from alot of spring pressure pushing the rounds up). so when the first round leaves the mag towards the barrel the second one shoots to the top of the mag and forward towards the barrel because theres no friction holding it back? maybe its just warn out

It has been suggested that Glock magazines should be downloaded one round than max capacity..

by who ?? glock mags should be fully loaded... yes it takes time for the spring to "work itself in" and comfortably hold 10 rounds but you should always use them fully loaded....

also make sure to give the magazine a little tap on the baseplate onto the palm of your hand, it helps settle the rounds a little.

the other thing to ask is are you using .40S&W mags in a 9mm or something ?
 
Ok wendall lets read that,

2.) On tough to seat mags, download at least 1 round. If a fully loaded mag is difficult to seat with the slide or bolt assembly in battery then download the mag by at least 1 round as a matter of habit.

he says on TOUGH TO SEAT mags... not every glock mag and not every user.. just the mags that are tough to seat... frankly your short selling yourself if you do not break the magazines by using loaded to full capacity, yes glock mags are tight at first but with usage they loosen up.
 
:rolleyes:

You should email him, and let him know how he's been misleading people with his silly advice.

I got the gun was cycling another round and jamming and not extracting the one in the chamber! lol

IF its loading 2 at a time, then YES, a mag issue, is it seated all the way in? How tight is the lip of the Mag holding the exposed round?
 
It was not extracting and feeding the second round. This gun has been used in competition at least for 6 matches without a hiccup with the same 7 mags. I checked the extractor and the ejector and they look good. I am wondering about a bad batch of ammo. TAZZ
