My take on a 22 is this… for plinking and shooting squirrels and other SMALL animals and targets they are great! However, a 22 is NOT adequate to protect you in the event you need it too, be it from people or animal attacks… a few weeks back I posted up about finding a pack of wild dogs on our farm. 2 broke off from the pack and came at me. I had a 22 rifle in my hands. I shot one, and hit it, twice. luckily, it changed its mind and retreated, but the 22 did NOT put it down. That makes a 22 UNACCEPTABLE to me for protection. If it wont kill a wild dog that is charging me, it is NOT going to put down a crazed junkie loaded up on meth looking to do my wife, kids, or me harm. Therefore, I never leave home without an ADEQUATE side arm now (being my 40, and now a 44 mag I just got). I just would NOT trust my life to a 22 PERIOD…
That said, I had a p-22 pistol that I had bought to use for target practice thinking, I can practice with it, and then fine tune with the 40… nope, I am dead shot with the p-22 and group to the left with my 40. I now recognize the need to practice with what I carry only…
Keep in mind, these are conclusions I have come from MY OWN experiences and only apply to ME DIRECTLY… you may have other experiences.
