Pmag 10/20 - How To

[NiteQwill]

I used the idea from the original post

Required materials:
20rd PMag
3/8" diameter rod, 6.20 cm long
2-part epoxy

Tools:
hacksaw or dremel to cut the rod

The original post gave me an idea. I originally was going to convert the Pmags to 10 rounders but thought I could convert them to 10/20's instead.

1. Epoxy a 6.20 cm 3/8" rod in the C on the follower.

2. Assemble as necessary.

3. The mag will hold exactly 10 rounds.


*NOTE* The included feed lip cover will not fit with 10 rounds. Download to 9 and you should be fine. I did not want to overtrim the rod I would inadvertently fit an 11th round.

Good job man!!

Great idea I never thought about using a rod epoxied in.

Nice job,

So you have to use a 30 round follower correct?

Nice and quick

Yes. It works best. I tried it with the 20 rd follower and it just didn't seem "right."

For 3/8" rod I went the inexpensive route: a clothes hanger

haaaa haaa, what ever works... but might not go over well with the wifes dresses on the closet floor.
I guess one hanger can do a bunch of mag mods...so they are 6.2 cm long?

I'm sure you can make it up to the wife somehow...

Yup, just cut each rod to 6.2 cm. One standard clothes hanger can easily do 5-6 magazines. FWIW, I used a sturdy (hard to bend) clothes hanger not the ones that you can buy 25 for $5 at Target

Forgot to mention, let the epoxy fully cure before moving stuff around. Don't ask me how I know...

The hanger material was a nice touch. To be honest, I tried doing it with steel rod the first time around, and the disimliar materials didn't bond well with either JB or epoxy. Now plastic on plastic, epoxy or weldon should be good to go.

An idea though for added permanence; once the epoxy cures, take a drill and cross drill the follower and rod and use a pop rivet to pin the rod to the follower. That way the rivet will bear more of the load, and the epoxy is just there to stabilize the rod from swinging. I cut mine down to 10s after being less than entralled with the flimsy bond with steel rod. I might have to order a couple more 20s to give the plastic rod a shot.

Last question, what's gonna be the group concensus on whether or not these should have to be epoxied closed after they've been verified functional?

Thanks for posting the exact measurements on the 20s, I didn't bother to measure mine after I fit them and then chucked the rod.

I found if you cut the rod a bit longer and angle the rod slightly towards the rear of the mag you can get the cover on and still hold just 10rounds. Just slowly trim rod to fit. Double checking the 10 round capacity.

I spoke to a Sheriffs officer about these at the range and said that if you epoxy over the button to remove the base plate that would provide enough permanency. He agrees the wording is vague but no access to the button removes the ability to reverse without ease. Much more than a rivet in the metal mag versions.

Need to bump this to push it to the top of my subscribe list

[glock_this]

read all the posts on this conversion topic and have 2 questions still please:

1. how do you dissemble the pmag/remove the base plate to get to the follower? it looks like it just slides off.. but is that really the case and does it take a lot of force to pull it off? any tips?

"Yes. It works best. I tried it with the 20 rd follower and it just didn't seem "right."

2. still not clear why you 'need' a 30 rnd follower? if you just make the rod the right length, what does the follower have to do with it - that is, why would the 20 rnd follower from a 20 rnd mag not work?

[xxdabroxx]

There is a detent in the middle you have to depress, rectangular shaped.

i think the 30rnd follower has the longer tails, so it is less likely to tilt???

[glock_this]

thanks for this thread, and read this as well, with the help of it I just converted 5 10/20 pmag kits. I did not use the 30rnd follower.. guess we will see if it 'really' matters

my feed lip covers still fit as well even with 10

could post photos if necessary, I also used a plastic 3/8 coat hanger as the rod & I used JB weld epoxy on rod and floor plate

Thank you, I have now "sticky'ed" your thread into infamy.
