chambering issue

[mhardy]

I am having an issue with my G21 glock. The first couple chamber perfect and then its hit and miss after that. Anyone have any thoughts on whats going on? This has never happened before, I was using the same ammo I have always used. Any help much appreciated

Is the barrel and chamber clean? Is all ammo the same manufacture or different? What type of ammo are we talking about?

hope you get your problem resolved. if youve put thousands of rounds through it by now, maybe its time to freshen up the magazine springs?

[NotEnoughGuns]

mags would be my guess. Then a good cleaning maybe.

[OneSevenDeuce]

Seems like a classic magazine issue. Have you marked your magazines? Do your others do the same thing?

[den888]

Yep, I would try different magazines and a good cleaning.

Ammo used was the standard white box winchester. The problem was with all of my mags. I use five mags that i rotate the hole time so each them probably only has 300 or so rounds through them.

For starters, I would give each of your mags a good cleaning. I would then take however many mags you have, I assume that they are Glock factory mags, and number each of them.

Inserted the empty mags in to the magwell, pull the slide back to check that the slide remains locked in the rearward position, until racked and released.

The next time you go to the range, keep track of which mag is giving you issues. You may need to rebuild them.

I had the same problem with the new gen mags.(the ones that can be used with the ambi release)

Limp wrist.

New mags, new recoil spring, clean. How many rounds / age is your G21?

[Colt]

Are you sure? I read many times that Glocks don't malfunction...

Seriously, though - mags are often a problem with pistols. Specifically mag springs.

[cineski]

Problems can happen w/ any gun. Especially those w/ a very high round count of just some manufacturing anomaly.

...then its hit and miss after that.

Can you elaborate?
