7.5 FK for the Glock Platform?

It might be possible, but why?

I would shy away from the 22-9r bullet type design, you are really limiting versatility by doing that IMHO. It's much better to go with a shorter case and have lots of bullets to be able to use. I also like to have easily accessible brass which the 7.5 does not have going for it.

I've wildcatted a few rounds in Glock platforms using easily available cases. I've gotten close to 7.5 ballistics with my 30 super which is a 9x23 (9mm largo or 38 super brass is used) case necked down to 30 cal. The 7.5FK runs a 95g bullet at 2000fps and I've got an 85g bullet to just under 2000fps in my 6" 17L all while fitting in a 9mm frame gun loaded to 1.150". Taking a 357 sig or the 9x25 case and further necking it down to 30 cal would be faster faster than my 30 super and could be a great g40 pistol round. This would meet and most likely exceed 7.5 ballistics in a much more available case without limiting yourself to a funky nosed bullet.

Moving up to the 35 cal I have the 357 sig, 9x25 and 38 casull glocks. I can exceed 2000fps with 90g bullets in all of them. The 9x25 can hit 2300fps with a 7.25" barrel and 2200fps in a 6" barrel. The 38 casull (really a 38-45 improved which is a 45 acp necked down to 35) will max at 2400fps in a 6" barrel with the 90s and 2700fps with a 65g bullet. All 3 fit into the 10mm frame guns wonderfully with room to spare for different bullets. I can run 65g up to 180g bullets at usable velocity.

If you're an energy nut, the 30 super can approach 750lbs of energy the 357 sig can touch 900 loaded to 1.250" and both the 9x25 and 38 casull can exceed 1000lbs of energy loaded to 1.280". The 10mm, 400 corbon and 45 super are all over 1000lbs from a glock as well.

I love your posts SS 3078. I funnally in life found that in life my tokarev round Is all I need in a handgun. Never thought I'd say that . Next project Is your 30 super as soon as I get the Money for the bar sto barrel
Can we somehow come up with the 357 sig necked to 30? How would you see this happening? Would be a dream come true in a glock. I don't know of Anyone making a base barrel like the 30 luger for the larger case head would you just have to start with a Barrel blank and cut the barrel bore yourself?

I would love to have a glock do this but also the tokarev isn't limited by oal and it already uses a 30 cal!! The only limitation is strength of the older guns And absolutely no way I have found to have a longer barrel made . I've gotten to 90gr at 2000 fps its a BEAST!! My purpose is to stop lugging a rifle and gear for it weighing in at almost 20 lbs backpacking..with a tok all you'd need is a few mags and the pistol itself!! I can't believe its not more popular its crazy you can make tokarev brass out of 5.56 brass and the rounds are ideally 30 cal 90 gr xtps! They are unbelievable and that last statement kinda reminds me of a shorter 300 blackout..hmm. crazy thing is it is just like it ! And with a longer barrel staying at 110gr or below it's absolutely nipping at the heels or equaling a 300 blackout in pistol lengths! And the recoil is basically non existint it's absolutely incredible..i have no idea why it's not more popular

I would love to see a modern firearm like a Glock chambered in 7.62 Tok. I was lucky enough to pick up about 4k reloadable brass. 90 Gr XTP over H110 makes a great combo

Hey bud! I don't want to post the loads on here but I'm fanatical about the cartridge lol... I have done my own chrono work and with a 90gr xtp my "light load" gets 1850fps. My hot balls to the wall load gets 2004 fps..it's absolutely unreal out of the 4.5 barrel . For penetration I'm just short of my 300 aac in wood with 110 grain round nose 30 carbine bullets. I shot the 90gr xtp into a light steel pot of water it blew the steel pot in half lol. Can you imagine the pressure wave to do that ? I also shot it through a steel thick frying pan the 10mm did put a deep dent in using 180gr fmj but not only did it penetrate it like butter it blew the water jug behind it to little pieces. Doing testing with this round shows above 1850fps it frags nasty but ALSO penetrates extreme hard cover making it ideal for medium game protection while hiking
I look at the tiny pistol and look at the tests and go how is this even possible? I can't believe that they came up with this round in 1933 or what not. I'd pay a stupid amount of money to have a 7.5 or 8 inch barrel . The very long oal with room to spare In the tokarev design is simply incredible but I'm right there with you with the glock idea it is a very old platform and isn't good at all for maxing out a round. I think even better would be the 40 necked down to 30 since then you have more volume in the width rather than length. Also to Have basically a relic you can ccw rather then 20 pounds of gear on a hike tucked away would be a dream come true . Any sort of extended barrel on a platform that can take the heat like a glock could literally approach or even perhaps equal a 300 black out of a short barrel! I think If we can find someone who can make the barrel we'd be set . As a reloader you know how easy it Is to shorten oal. I love was ss3087 has done by keeping the weight by finding blunt nosed rounds. We can do this . I would do almost anything to have it in a glock and living in extremely liberal areas I'd absolutely love to just have my CRelic for the outdoors...it is a beast in disguise I cannot believe how well they engineered this round If only someone could make an extended barrel...
By the way I use 90gr xtp and AA9 . The 90gr xtp round Is the best designed round I've ever seen its insanely tough yet creates a massive temporary or permanent cavity exactly what I want for the field when critters might be about that wish to eat me

As a side note I think the soviets designed it to be a complement to their 30 cal rifles and now with modern day reloading it Is the ultimate ak clone(300 aac ) companion..you can use the same brass same powder and same lighter grain bullets! It's a keeper for life .why hasn't anyone noticed with all the short barrel rage?

The first (American) conversion of 1911 to 7.62 Tok that I saw was done by the mono bloc method.
The breech end of a .45 barrel was cut off and reamed out. A .30 tube was sleeved in and chambered.
I don't see why that would not work for a 7.5 in a G20. It does for Imbel, FN, Perazzi, and Beretta on various guns.

Well guys If anyone Is still reading I found the solution
Order a heavy profile 308 barrel blank
Machine (easy for ANY mill ) the outside of fhe barrel
Ream to 7.5FK
I can't believe how easy this is
If only the freaking tokarev didn't have such a long locking lug at the bottom.
I looked over all the dimensions. It will work with 1.2 plus Diameter barrel blank
I am going to machine one for my glock in 40 cal since that's all I have. I will machine one for 7.62x25mm and one for 7.5FK
This is a dream come true and a barrel blank Costs about 100 bucks .it is obviously the steel barrels are made out of so it's built for this very purpose another plus .I guess I will check here on the Services board who can machine it otherwise I'll find someone local. But here you guys go no more looking for custom barels and paying possibly thousands IF you get a company even interested in doing it

I made this post almost 4 months ago, and after a while, I forgot about it.
But coming back and seeing that it ended up gaining interest was surprising to me.
I am glad that I inspired something interesting like this.
