Tagged for info I have a 29 on the way and have a 20 so I had similar plans.

 

I've had a few FTFeed malfunctions with a 21 mag in my 30s. Both times the round was stopped at the bottom of the ramp. I guess its called a "Nose Dive". Both times I was also using an X Grip adapter

 

Exactly. The round was stopped at the bottom of the ramp in every FTF. Hmmm, wonder if the same problem would occur with the G21 mag in the G30 (or G20 mag in the G29) without the X grip.

To attempt troubleshooting, I would say run the full size mag without the X-grip and see if the problem still occurs. If not, then maybe try to grip/hold the differently? Maybe modify/trim the sleeve to fit better if the second option affects reliability.

 

I haven't used my G20 mags in my G29's so have no first hand experience. I remember a long time ago in either the Ten Ring or 10mm Reloading threads, guy(s) complaining of G29 feed failures when shooting their hotter reloads when also using a pinkie extension.

At that time, the ones reporting that issue would have failures when using the extension, the same rounds without the extension would feed fine. I think I recall the final analysis was the extra purchase of their grip on the extension was torquing or somehow otherwise misaligning the magazine and causing the feed issues.

Have you tried maybe playing with OAL to see if you can mitigate the issue with a longer or shorter round?

This may be it. The extension of the magazine below the grip may be torqueing the mag just enough where the bullet does not align correctly. I haven't have this happen using 17 mags in my 26, but I don't use the bottom of the mag as part of the grip.

 

Keeping an eye on this one...planning to pick up a 29 to go with my 20.

 

I carry a G20 mag for my G29 Gen 4. Don't jam the magazine into the gun push it up until it clicks. I carry the 10 round mag in the gun and the G20 mag in case the SHTF big time!

 

I've used G-21 mags in my G-30 plenty of times with no issues but I was not using any sort of mag sleeve. Off topic but I have also run a G-26 & G-27 with mid-size and full-size mags, with and without mags sleeves, with no issues as well. With all above-mentioned pieces, FMJ & JHP was used.

Think this could be it. The extension of the G20 mag out of the G29 magwell is longer than other configurations that I run with the X grip (i.e. G19 mag in a G26) so there is a lot to hold onto and potentially torque.

Going to try it without the X grip to see if I get the same problems.

You may try using the search function in either the 10 Ring or the 10mm Reloading threads in the Gun Related Club subforuns.

I wish I could be more helpful but frankly I am a search Luddite.

 

Just shot my G29 with an x-grip. No trouble, but I really had to seat the mag.

 

I have a newish G29 that I've shot several times with my reloads exclusively. Everything went swimmingly and I used the G29 mags that came with the gun.

Today, went to the range and used a G20 mag in the G29 with an X grip for the first time. It felt soooo good but...I was getting failure to feeds constantly. I'm not sure if it was my reloads or the G20 mag with the X grip that was causing the problem.

I did also have my G20 with me and ran my reloads through it with zero problems.

I suspect it's actually the G20 mag with the X grip that was causing problems. I felt the mag rocking a bit when gripping hard which I usually do with my 10mm pistols.

Has anyone experienced similar problems? I probably should shoot some factory 10mm rounds through the G29 with the G20 mag and Xgrip to rule out my reloads but don't have any factory ammo on hand at the moment.

It'll be really disappointing if the X grip thing doesn't work out with the G29. It felt really good and was planning on carrying it this way (as weird as that sounds since it extends the grip significantly).

I've also run X grips on a number of other Glocks and calibers and have never had a problem so this surprised me. Anyone have a similar experience?

Oh yes! In my avatar you you can see that I have configured my G29 just as you described. It easy to develop superstitions about the cause of FTF. I have tryed every size guide rod in an attempt to eliminate FTF. I had long exchanges with Wee Willy about this. I think using Underwood tapered polished ammo when I CC will help to eliminate FTF. But, That ammo is very expensive! I use 10 mm ammo I buy from Georgia arms to practice with.

The Georgia arms ammo is heaver and gives me a little more kick than my Underwood. I wont say that I never get a FTF but it's rare. I found it's all about how you hold the weapon. I found that when I locked my elbows that I was more prone to get a FTF. The weapon must be held in place using arm muscle not locked elbow joints. If I lock my elbows the HOT 10mm ammo tends to bend me over backwards, my body then dissipates some energy that the gun needs to operate. It happens so fast that you don't know it happening. By holding the weapon firmly in space with my arm muscles, the arms return the energy that the weapon needs to operate. That's my theory. I have never had a FTF if I shoot one handed from the hip, but then I never hit what I aiming at when I shoot from the hip. I'm a tall slender person. I think that when I shoot from the hip close to my center of gravity, It's easier to hold the gun and your body still. Extra weight helps when firing the 10mm G29. I have proved this to myself by putting on a back pack with 30 pounds of water in it. Then the G29 is flawless. Size/Mass matters when firing hot ammo out of the G29. BTW, I like to fire quick bursts of three rounds each at steel targets. I squeeze the gun hard enough so the red dot quickly returns to target and I'm firing the next round as soon as the trigger resets.

This is interesting. If true, that's a bit worrisome. I don't want to worry about whether my elbows are locked or not when firing my G29 and whether I'm going to induce a FTF, especially since I was going to make this my EDC.

I will try it next time at the range, locking my elbows and then just using my arm muscles. Come to think of it, I was locking my strong side elbow when I got all those FTFs. So now I have another variable to consider (my reloads, the X grip or the locked elbows thing). Hey, I thought Glocks were supposed to go bang no matter what! [emoji39]

P.S. I like your red dot set up. Coincidentally, I am sending my G29 slide out in the next few days to have it milled for an RMR. Have my G20 set up this way and love it. A 10mm Glock with an RMR is quite a formidable weapon as far as pistols go.

why do you need or want the X grip part ??

 

Good question indeed. I just like how it feels when I grip the gun. But not at the expense of reliability. I'm going to do more testing. If I find it really is the X grip that is causing me the problems, I'm getting rid of it pronto.

Practice with your elbows unlocked until it becomes natural and a habit. Bad habits are hard to overcome. I have been told by some that a red dot slows down target acquisition. With years of practice that too has become second nature for me. When I pull my weapon and extend my arms the red dot pops into view without much thinking about it. In a SHTF situation I think I'll be throwing rounds down rage as soon as I see the target in the window, while I'm looking for the front sight or red dot. The front sight and red dot normally pop into view at the same time for me.

I'm lucky enough to have a firing range on my own property. I get to practice a lot.

 

For you that are having NTBOFR OR ND, nose to
bottom of feed ramp or nose dive,
try taping a shim on the bottom back of the mag,
just a little that does not extend up the back
of the mag, it will make the bullet nose in the mag
aim a little higher.

To better see the slop, take the slide off and insert
a loaded mag and push fore and aft on the bottom
of the mag, note how much movement the bullets
nose has.

Not saying this will fix your NTBOFR, ND, but it might.

Maybe if you push up on the bottom of the mag it will
get the nose a little higher too, I notice the mag has
a lot of slop up and down when the mag is empty.

 

I know this is a (very) old thread, but maybe folks are still active who were discussing. I have a g29 with tungsten guide rod, KKM precision barrel (for the chamber support), upgraded trigger shoe, and slide cut for a trijicon RMR red dot. I exclusively shoot reloads (often with virgin brass), with various loads around 1100 - 1250 FPS. Ever since I got the red dot installed, the gun has been beating up magazines and spitting them out of the gun. This is happening with g29 mags as well as g20 mags. I have the pinky plate installed on some g29 mags, and not on others. I have the x-grip sleeve on the g20 mags as well. I took it to the range this last weekend after consulting a gunsmith about the problem. He seemed to think my issue is related to overly hot ammo, and "magazine surge". So... I moved down to a lighter load, and a brand new factory g29 magazine, and replaced the factory mag catch with an aluminum one. First magazine, on the 3rd or 4th round, magazine is kicked out of the bottom of the gun. The ammo in question for this test was a 165gr hollow point with 11.1gr of alliant blue dot powder, and a S&B large pistol primer, this load clocked at average 1172fps.

This is becoming frustrating, and I don't know if I have now gimped my pistol by putting a red dot on it or not. The gunsmith indicated that the reduction in mass by removing that much steel and replacing it will less mass (aluminum red dot) may lighten the slide enough to alter things mechanically and cause my problem. The other thing is that the area of deformation on the magazine notch is very very slim. It seems to indicate that the magazine is only retained by the slightest of contact with the mag catch, and I'm honestly not sure if that's working as it should.

Has anybody else seen this with a Glock, g29 or otherwise?

Thanks

Interesting. First I’ve heard of a red dot causing magazines to be spit out.

I’d remove the red dot and shoot the pistol again. You’ll know in just a few rounds if this solves the problem. Better yet, if you have a buddy that has an unaltered G29 slide, try shooting it with that and see what happens.

I wonder if something is preventing the magazines from seating fully. Do you hear a click when inserting the magazine and have you tried tugging on the magazine from the bottom to see if you can get them to pull out without touching the mag release? I’m thinking there is something interfering with the mag being seated correctly. Something sounds out of spec. Might have to send it to Glock to have them take a look.

My department used to issue G22/23 to patrol and G27 to CID. We issued G23 mag with grip collars to them for uniform use. They did to seem to have a higher than normal malfunction rate which we attributed to rearward pressure on the toe of the mag base causing the feed geometry to angle more to the feed ramp. This was all we could come up with but it sounds similar to your issue.

 

I have a G29 and G40 and have had no problems using the 40 mags in the 29. However, there is a noticable amount of movement of the G40 mags than there is the the OEM 10 round G29 mags. The mags look and measure the same but yet the slop is there. In fact, when I replaced the slide stop with the extended version, most of the mag followers slipped under the lift arm of the stop, causing the slide to not lock open on the last round. A little tweak of the stop arm that engages the follower solved the problem and now all is well!

I can't say I'm a huge fan of the X collar, as it feels weird to me, however, it's worse without it! At least no malfunctions. Make sure your mags are properly seated and that your support hand is not contacting the mag release is about all I can suggest. I wish I could be more help.
