The more I look into the 9mm carbine, especially the KelTec Sub2000, the more interested I am. I like the idea of a low cost rifle with a high potential for inexpensive fun. If it was just about the low cost enjoymemt, I wouldnt need to look any further than the .22lr but the potential of the 9mm carbine for self defense is more appealing to me than the .22.
Now, by no means would the 9mm be my "go to" "fighting rifle" (except maybe during a zombie apocalypse) but I think it good to keep some some optimum SD ammo for every gun you own.
I find it appealing that out of the 16 in. barrel there are some 9mm loads that approach the .357 magnum in ballistics. So what Im curious about is if you folks think there are any exotic loadings (super light and fast) that you could fire out of a 9mm carbine at velocities over 2000fps. And if there were, would you recommend it?
This question stinks of "noob", I know...
Look forward hearing your thoughts. Thanks.
