Any u guys own a Glock 20 10mm that has had problems with ftf and fte. My buddy is at my house and having problems with his, its fairly new, seen about 500

The only thing I can think of is try a different mag and/or find someone who knows Glocks pretty well. I have a pair of G20s and they just shoot with no problems. It's not my favorite action, but they work well.

Can you give more detailed info on what it is/isn't doing, how often, how many rounds in the mag, stovepieing. etc? There are a lot of different ways a gun can malfuntion as you described.

I'd also like to know if your using aluminum Blazer ammo.

Reloads or Factory Ammo?

All types of ammo. Remington and pmc and its really bad with hornady. About halfway through a mag it either won't eject the spent cartridge or it won't feed.

Limp wrist?????????? Based on very lwt frame....one can short stroke the slide based of soft wrists.

If its not related to a firm grip

There are too many other things that need to be checked on a new gun.

Was any parts replaced...meaning not factory??

If it was...return the factory parts and see if reliability returns...if not find a glock armorer or contact glock for repairs.

Sorry I could not be more help

Is this a G20SF (Slim frame)? I think there's magazine compatibility with old/new frames. Could be limp wristing as suggested, 10mm is a lot of bullet. This would be more apparent as you got to last rounds in 15rd magazine, and total weight of gun goes down.

Thanks for the help guys, I think we have figured it out, it has only had this problem after a good cleaning with REM oil. Dried it completely out and it shot a hundred rounds flawlessly

Guess they didn't include a Remoil bath in those YouTube torture tests...

I'm sorry. I just couldn't resist.

Rem oil was designed for slow moving shotguns and bolt guns.

It has the consistency of water. I suggest using a heavier gun oil of your choice on the G20.

There should be NO oil in the firing pin channel.

alright ill do this the easy way. haha since were both in Maine. do you and your buddy ever end up in the saco area? im a glock armorer haha if you end up this way. send me a PM. ill give it a once over for free.

dont use the cheap KTP or cabelas china mags. they are junk and wont feed right.

also the spring that sits behind the extractor may be worn , the 20 takes a serious beating in the action.

has he detail stripped the slide? if so the extractor has a small bar behind it that runs through the slide assembly. one end of it is angle cut, while the other is a plunger shape. the angle cut end needs to be facing the front of the slide and during reassembly , the angled face of this piece NEEDS to be facing inwards towards the slide, if not the extractor has no pressure on it and will not engage the round.

Good to hear issue resolved. Happy shooting with that 10.

Keep in mind some of the advice already given anyway.

Yup, I don't know how many people I've had to tell that that little hole in the slide is NOT a oil filler hole.

I've oiled mine and wiped the excess away just for corrosion control. Then I dust it with dry teflon. I do the same with the mags. I can load 15 and my one 17rnd g20 mag up full without the loading tool.

Prudent to wipe off the breechface once in a while just in case.
