Hands down, what is the best pistol caliber?

this probably wont get read but Its all about personal preference (and your wallet size) practice is necessary and practice cost money remember you become the weapon not the gun guns don't work by themselves but hollow points work better what ever you choose make sure it works shoot at least 150 to 200 rounds of the ammo you use with out any jam or failure to make sure your gun will cycle that brand of ammo correctly. 45 ammo cost more 9mm is faster and has more accuracy at longer distances but most hand gun fights occur at 0 to 12 feet and at night your best defense is a very bright flashlight "surefire" is the most popular but there are some cheaper alternatives but get night sights "true glow" for exa the above is stated as informational purposes only always consult with a trained professional before engaging in any self defense practice
