7.62 x25 conversion for the glock 20

I rember seeing this topic discussed sometime ago but i can't seem to find it anywhere. Remind me again why it may not be a good idea?

I think it might be a good idea for self defense in the case where the offenders are wearing body armor.

The 7.62x25 is known to defeat kevlar helmets as well as up to level IIIa vests.

I do not know if it would be able to do this out of a shorter barrel, but I would expect it to have greater penetration than a TMJ or even FMJ light weight high speed 10mm round, or even the 9x25.

I had made mention of the 10mm necked down to 0.308" as a variant of conversions possible with 10mm guns with a mere barrel swap.

The 224BOZ(10mm necked down to .224") was one which was touted as being a penatrator, but this never took off. Besides pointed bullets can cause feeding issues.

Now the 9x25Dillon is also a fast little zipper with the 90 grain bullets, I am still working with a 115 hollow point and various powders to achieve some performance for possible hunting situations.

It would be interesting to see a saboted 224 bullet in this application to see what is possible. But no one is producing any sabots in this configuration, although it is feasable.

Who knows what the future holds...

i Have always liked the idea of the 9 x 25 but i have heard that it may cause damage to the frame? 2nd don't the 135 10mm close to the 7.62 x 25 and 9 x 25 dillion.

Its just that the 7.62 x 25 is an inexspensive round to purchase and it would seem to make for a nice practices round.

I think they are too fat, not fast enough (but the 9x25 is pretty fast), but the key component is the alloy of the projectile. The 7.62 x 25 bullets are much harder than the other two.

I suspect if Barnes were to make a solid copper FMJ 10mm 125/135 for the 10 or the 9, that would do it.

...but yeah, the 7.62x25 is super cheap too - also somewhat corrosive. I do not think it would damage the frame at all if it were cleaned on a frequent basis (certainly recoil would not be an issue).

Also, not sure how speedy these are in the G20 sized barrel...

At any rate, I would love to find such a kit (4.45" bbl.) for my G29. That would be fun.

guys I think i screwed the pooch on this one. I was able to make contact with the guy on the you tube 7.62 x 25 conversion. He said he Had over 4000 rounds through his 20 no signs of wear on the frame and he was in the process of a 29 conversion. I was hopeful that he would be amiable to either doing the same for me or helping do my own. Went back to send an email and found that he had taken his videos down. i am bummed. I hope to be able to get more info on this project as i think it would ad to the versatility of the glock 20/29. If i can remember some of his comments he did say double feed ramp in the barrel, ejector to handle smaller case, modified mag follower, he had to make his own firing pin as the glock would not reliably ignite 7.62 rounds (primers too hard). dam i was hoping for this . I think the barrel was made from a .308 ???? not sure on that point. any body else?

well if he is going to that would be great but in the mean time i guess the 9 x 25 is a nice option. Its just the cost of the ammo. "shadow" can you pm some specs or point me to any of your links to this subject as if i remember correctly you have been the biggest proponent of this round for some time. thanks in advance.

Well that completely sucks. WTH would he have done that? I wonder if the ATF or feds made him take it down? - Or maybe he is going straight to the patent office (good idea if that is the case).

I would really like to know how to get a hold of that guy.

Well - it is gone like it never even existed. I can't find the video at all.

At least we know it can be done and that it works!

The mods as I remember were:

1. Modified magazine follower to tilt the bullet side of the cartridge up.
2. Double feed ramp.
3. Heavier rate firing pin SPRING (it was the spring that wasn't strong enough - made himself because nobody else made it).
4. Home made barrel made from .308 barrel stock.
5. Some modifications to the extractor (not much).
6. And one part I can't remember what he called that had something to do with keeping the slide in battery? (I didn't get that part of it).

The more I think about this conversion, the more I would want one.

I think it is an outstanding idea.

Hopefully somebody would start producing this.

i Agree kegs, the ammo prices and plinking factor is awesome. I would purchase a slide/mag conversion kit for upwards of 250 to 300. no more than that though...

Leadslinger, There is a lot of stuff in the 10mm Reloading section on the 9X25 Dillon, I have been experimenting with some loads using powders not published in the Lyman book (all two pages of it) There have been others who are also working up data as well and publishing some good notes and pictures.

One thing I did conclude is that this round does perform better in 6" and longer barrels, I haven't been able to get the higher velocities from my 5" barrel others have seen.

Now I don't know what powder McNett is using in the commercial loads he is selling but it is performing way better than what I have tried so far!

The test I was doing a few days ago happened too late in the evening and the lighting was throwing off the readings for the CHRONY...that an the 9X25 conversion barrel for the G-29 got jammed/stuck during reassembly(recoil rod/spring jumped off the lug) so I didn't even get to test with the short barreld Glock.

Look for the Lyman data posted here http://glocktalk.com/forums/showthre...=228796&page=2 go to post #38 and also the others who have done testing.

I hope this helps...

I've never heard of a 7.62x25 conversion before, but I wish I did while the video was still up. I like the round, and would like to have more weapons that fired it, especially something in a carbine.

I'll have to look around the internet again, I know somebody was trying to build an AR-15 conversion for the tok round.

I have shot an AR in 7.62X25 (Tokarev). What a fun and cheap round. I don't love the idea of using corrosive ammo in a direct impingement gun. Lots of cleaning to do after shooting, and I suspect you will be changing that gas tube fairly often. I am not sure who made my friend's rifle, but here is a Google find.

The video with the 7.62x25 hand loaded with 200gr Sierra Matchkings made me REALLY want a 7.62x25 upper.

I started a thread on this idea a long time ago but it seems this forum only has a limited archive. When I tried to load a G20 mag with 7.62x25 Tok ammo it was too long. Maybe that can be dealt with using a new follower but I could only get like 12 rounds in it and they were angled way up in the front. It didn't take much of a bump on the bottom of the mag to get it to spit the rounds out and when that happened a round further down in the pile was pointing straight up and jammed the whole thing up. They just don't fit.

Well some of us saw the video before it was pulled - Someone has successfully converted the G20 to tok and it held more than 15 rounds (I think it may have been 18). It did not jam during several strings in the video. Look further up this thread for the design specifics (some of which are missing).

It bothers me that Lone wolf or someone similar hasn't made a conversion for this yet. The round will work and it has some advantages to it that the 9x25 and 10mm can't meet - most of all economics.

I didn't say it was cheap. I was merely pointing out that Barnes is making such a bullet. You could get you some maybe and roll your own for less.
