While I’m not particularly interested in the Brno pistols themselves, I do really like that 7.5FK round! Just imagine a G20 or G40 pistol in this caliber. I realize the 9x25 Dillon exists and it’s pretty close, but I think the 7.5FK edges it out. The FK is probably too long to fit in a G20 mag, so swapping the barrel is likely a NOGO so it would probably require a new frame and magazine. But, I’m confident that Glock could pull it off if they wanted to.
CMMG could also make a killer Banshee in this round too!
