I had given the Kriss consideration but wasn't looking for another 223/556 platform.. besides, it's fugly!
Discounting all the handgun bull pups as I have that covered under another project. I've fired the FNH handgun and really enjoyed it except for the grip size. Unfortunately I found the grip just a bit to large, a common complaint I'm aware of. I got to handle the PS90 a bit awhile back and liked it. The round itself has advantages and disadvantages when compared to rifle or pistol rounds. I like that's its different and somewhere in between.
I'm still only reloading for handgun right now but I've become comfortable with it and reload most of my range rounds now. Initially I'd likely bulk order a few 1000 rounds and save the brass to reload later.
Still contemplating.. Might have to pop over to see Chris soon.
