I have heard that as well. So you're saying it's pretty much on par power-wise with 9x19? Way to go, Euro gun-grabbers! Make it illegal to own 9x19, offer up its nearly identical brother instead! I wonder if .45 GAP is legal in places like Mexico which ban all "Military ammunition?"9x21 is primarily a European cartridge, though I think it has seen some adoption in South America and parts of the middle east and Asia. It's my understanding that the intent behind it was to offer a cartridge of different dimensions so as to be different from the NATO standard 9x19, as some countries do not allow civilians to own firearms in "military calibers".
I would think if you are wanting to go that route, the .38 Super would be a lot easier path and has more power and uses the same bullet.Is there any, even slight, advantage to having a race pistol chambered in x21 rather than x19? A tiny bit more accuracy perhaps?
I have shot .38 super, and it's max pressure (36,500) is more than the more niche, less powerful, less popular 9x21 (34,084). Maybe you use cheap ass cases or push your loads past max safe pressures to shorten the life of the cases.Gee, I've been shooting 9x21 for about 20 years. Load it long like a .38 Super and run 'em hot.
If you load it to 9x19 COL, then it is simply a 9x19 that head spaces funny.
For whatever reason, the 9x19 and 9x21 can take more pressure than a .38 Super case. Love people talking about what they have never used.
Remember, don't buy any 9x21 guns. Just let me know about them, please.
