One thing to rember that even a .22 is better than nothing.............just the fact of a gun in your hand
will stop most people from advancing and make them think about getting out of the area. The thought of
having bullets hitting your body will usually make people think twice if it is worth the problem.
22,25 and 32 cal guns have a 30 to 45% one shot stop rating, meaning that it normally takes 2 - 3 bullet hits to stop
an attacker while the 35 to 38 cal loads have a 69 to 78% rating, meaning 1 to 2 hits are needed to stop an attacker.
One note, the 22 or 22 mag are not listed as a self defence cartride , due to the bullets make up and as stated are the
last choice that a person should use to save them from harm, since there are better calibers out there and most gun
authorities say that the .380 is the minimum load that should be considered for self defence and even this gun in a
automatic pistol can jam with the wrong ammo.
Good luck and I hope you find a unit that will work, if the time ever comes.
