yeah idk, 9mm is pretty much the sweet spot. i mean, sure + 2 rounds would be nice, but i dont think this will really catch on.
its very similar to what federal did with the .327 fed mag. its like a .357 but alittle smaller diameter, supposedly allows a small revolver or more capacity, and also less recoil than .357.
but.. i dont think that its better enough to overcome the market density of the common calibers out there.
This has been my thoughts exactly. The 30/32s have enjoyed an almost cult following for over a century. There will always be the 357/38/9mm at the same weight, greater velocity, but lower capacity or larger frame size. I'll fall back on sectional density. Obviously if weight and velocity are similar, the one with the WIDER projectile leaves a wider hole and the one with the NARROWER projectile offers more penetration.
So it comes down to what your target is and how far it is. I think it's going to be a hit with 32acp and 327federal fans, and might make a splash with anyone who had resigned themselves to the SW EZ and similar sized 380s.
It's definitely going to be a niche caliber, but I could see it eeking out a place in the market for lower recoil shooters.
It could be a lot of fun in larger guns. Steel frame 9mms already enjoy a firm hold on pistol competitions because of their capacity/low recoil. Can you imagine a CZ Shadow II with some 23+ capacity in 30 caliber? We'll have to see how well it does but I think it won't be long before someone is trying it out.
