yes, the Keltec locker is a lot smaller and lighter
but unless you "need" to wear it in a bra, under a pony tail, or in a wristband rig, its size and wt are of no matter, as vs the far more powerful Kahr 9mm, which COULD very well mean life or death. Now IF you reload for that locked breech 380, and get its power up over 300 ftlbs, the diff would be quite a bit less, typical 380 ammo is 160 ft lbs in that short of a barrel, when you actually weigh the bullets, and chrono the loads. It AINT much, the same power level as a Stinger from a .22 rifle barrel. Yes, I DO know that you can't put a rifle in your pocket. Do YOU know that I aint TALKING about rifles, per se? I'm talking about the EFFECT of the bullet strike, not the gun that fired it. In other words, if you wouldn't feel comforted holding a .22 rifle, u should feel a LOT less comforted when holding a 380 with factory ammo. The .22 rifle is a LOT easier to place swift head shots, than is the 380 pistol, and it's also more likely to pierce the skull.
