I have both, like both Hi-Point 995 and Kel-Tec Sub2000, like both very much. Picked up the HP good long while ago 'cause I didn't expect to own any pistols that interchanged with the KT. Then later decided that I just must have a Beretta 92 in the stable so found KT in Beretta config too.
Mag capacity of course is what the HP995 is most dissed for. But what the hell. Also, those mags get bent easily; most all feeding probs with the HP is mag related. Easy to tweak feed lips back more narrow though, generally all that's necessary.
Both are just fine for torso shoots out to 125 yards with just the iron sights.
The KT subbie has the possibly very big benefit to one of folding up into backpack/briefcase size. And 33 round Glock mags or 30 round Beretta mags (the Beretta mags are really nice, have built in spacer that just extends the grip frame neatly.) Dunno what SIg makes long mag wise.
Anyway, I find them both nifty and effective carbines; I have the older 995 with the Planet of Apes stock, I love it like an ole ugly dog. I like the KT cause it's kinda the opposite, sort of slightly futuristic and the fold up always gets a wow from first time folks see it.
The KT is much lighter than the HP, btw.
Oh, but the world class pistol caliber carbine I own is the Marlin 1894c in .357 mag.
