View Full Version : Glock 43X/48 in 30 Super Carry.
I was dreaming about a 17 or 18 shoot Glock 43x. If Shield Arms can do 15 rounds of 9mm, what about 30 Super.
I cartridge that recoils slightly less than 9mm in the 43X platform would be perfect.
I’d consider it in a regular 43.
I am sure the AM will turn out Glock comparable barrels this year....and maybe Shield will modify their mags for it....
As I understand the 30 Super Carry has 50 thousand + PSI. 9mm max pressure is 34,000
I'm sure it will be a great 100gr 30 cal for carry. If that's what you want to carry. 9mm is as week as I will go. P365XL is the perfect size. It's not like I'm running around dressed like a Hooters girl trying to conceal.

If you're suggesting a simple barrel and magazine swap for 30SC it won't work.

Have you calculated the hoop strength and bolt thrust, or is it the extraction that concerns you?
Edit: I did some napkin math on bolt thrust. It should be around the same as 9mm +\- p, if I used the right amount of fingers and toes.

Can you elaborate? Is it an issue with some slide parts like extractor and ejector?

Dudes successfully use .40 (10mm short) slides with 9mm conversion barrels. I wouldn’t be surprised to find that 8mm SC works just fine in a 9mm slide. A half millimeter or so difference in rim radius doesn’t seem to be a big deal for some guns. I think 9mm has more taper, so I could be wrong.
Every parameter of this cartridge seems as though it was designed to be a straight swap into existing 9mm guns for manufacturers. Even the 50,000psi pressure ceiling might have been chosen for that reason.

The breach face diameter is the issue. Like those who've converted a 40 slide with a 9mm barrel, it might work, but it's not the best solution and I can't see it being reliable enough to bet my life on. 30SC is the flavour of the month, another solution to a non existent problem.

I’m not sure I’d call it the flavor of the month, since I don’t think much of it even exists yet.

That's true.

Not a matter of might work when converting a 40 to a 9mm with a conversion barrel. Never seen one not work all mine have. The issue for me is why spend twice as much for lower performance ammunition for just 2 extra rounds.

Another very valid point.
For me the draw to it was for the micro sized guns like the Glock 43. The lower recoil with an extra round or two is pretty compelling. But all the reviews Ive seen or read they say the recoil is basically the same as 9mm. At that point the minor increase in capacity isnt worth it for me. But Im also not against it. If it takes off and ammo becomes commonplace and cheap, ill give it a try.
Even the 50,000psi pressure ceiling might have been chosen for that reason.
That limit could be driven by the properties of brass and primers.
Take brass much higher than 50kpsi and starts to act a bit like playdoh.
Another boutique caliber that’s near unobtainium and costs a dollar or more per round?
No thank you.
Just for information, the current magazine has the depth for the cartridge length, estimate 13 rounds for capacity(43X)(I will confirm this when I'm in again) I will also try the 43, maybe 8. Keep in mind this is in the current Glock magazine. The only gun in with that caliber is a SW EZ. As some may know, they rely on slide weight to compensate for the lighter recoil spring. With that, the slide weight on the SC EZ is pretty beefy compared to the 9mm version. I won't talk about the EZ positively as a note.

No thank you.
The ball is roughly .50 or less.
The ball is roughly .50 or less.
Is that suggested or true cost?
A quick search engine scan showed the cheapest FMJ available at $1.00 per round for 200 rounds. JHP ran from $1.35 to $2.35 per round.
It may eventually come down in price and maybe get close to 9mm if adoption is widespread, but I don't ever see it being as cost effective as 9mm.
I will take a picture for you---
tiny bit more but not $1. ea. I do agree that I would not buy with limited supply and I forgot to check capacity.

update, although I had to hold them in, 12 rounds in the 43x, 7 in the 43.
