ETS Mags with TF Basepads

[stick]

Long story short.  My USPSA PCC won't feed Glock 33 round magazines.  It's a mystery.  Even the Manufacturer can't figure it out.  ETS mags work fine in that PCC as do regular 17 round glock magazines.  So here's my question:

Has anyone got the Taylor Freelance PCC +10 Basepads to work with ETS Mags?  I can only get 35 rounds into the magazine.  I've looked at several videos, but i can't find anything definitive on it.  Plan B is to get a MBX mini.  

 

Pictures are worth a thousand words.  pictures would definitely help!

I'm using ETS mags with my MBX Mega extensions without any issues, unless they get full of sand anyways.  They hang a little when I load them, I think right about the 33-36 round mark, and I usually just give it a little smack on the table and then I'm able to get them loaded the rest of the way without any issues.  I haven't tried the ETS tubes with my TF +10's yet, they're on Glock 31rd tubes, but I would just make sure that the follower isn't hanging up somewhere as it transitions into the extension.

From my research, I believe its the follower.  I'm trying to find someone who already made the necessary modifications.

I just went through this issue.  The follower is getting hung up on the basepad, which is smaller in diameter than the inside of the ETS mag.  You'll have to file down the basepad to eliminate the step the follower is hanging up on.  It's about an hour's work, but you'll have 41+1.

 

Also, with your 33rd mags, I had fits trying to get mine to work.  Mine would go salt shaker with and without extensions.  The problem lies with your ammo.  These mags, especially with extensions, are very sensitive to OAL.  The sweet spot with my ammo was 1.135".

You need to file the back side(long side) of the follower so it doesn't catch the extension.

Don't need to touch the extension, unless there's a bur.

The TF basepads were not designed for the ETS mags.  There is a significant amount of material blocking follower travel.  Simply modifying the rear of the follower is insufficient with this combo.

Can you give me more direction?  What exactly am I filing down?

I’ll see if I can figure out how to post a photo of mine.

Do the same on the rear where the follower will hang up on it’s downward travel as it leaves the magazine tube and enters the extension.

Thanks, I'll pull out the dremel and see what i can do.

I’m sure there’s variations between mags, followers and extensions.  

 

I’m currently running an ETS mag with a TF +10 extension. Have about 1000 rounds through it without problems.

 

No mods were made to the extension, only the follower. 

 

Reason I would advise against modifying the extensions, if it’s not needed.  

the extension with oxidize if you expose the bare aluminum.

Robin Taylor told me the extension weren’t designed for the ETS mags, hence why they commonly have issues with that combo.

 

I’m really not concerned about oxidation issues

I actually just ordered an mini MBX.  They claim to work without any modifications.  I'll just give my glock mags with TF basepads to my daughter.

[CalTeacher]

I have the MBX extensions as well.  They don’t require any modifications.  You may, however, need to modify your mags and followers slightly.  They have a video on the website that shows exactly what to do.  Super easy

Thank you.  I watched it before I ordered the extensions.

The only issue I had with MBX minis and ETS mags was the follower hanging up while loading, right about where it crosses into the extension.  I rounded off the edges of the follower all around and, while they still hang up a little, I can push past that point and they run great.

I just got in the MBX mini.  I installed it and loaded 47 rounds into the mag without any mods.

^^This right here! You can do your second one in 15 mins with a dremel, after you’ve spent an hour learning where to grind on your first!
