I am aprox. 1 week away from purchasing a pistol for home defense and was pondering the effectiveness of the different caliber pistols--9mm, .40 cal, and .45 cal. pistols. I have noticed on many different sites you can find the percent of stops you have with each caliber. The funny thing I have noticed is there is not much of a difference in hollowpoint expansion. The shop where I will be buying the gun claims that as long as you are using hollowpoint ammo all 3 caliber pistols I have mentioned are equally effective at incapacitating a person! I presently own a Sig 239 -9mm pistol and was thinking of buying a .40cal. pistol or .45 cal. pistol but if what the shop owner said is true about all caliber pistols being equal in incapacitation then the buying field is wide open ! Do any shooters have both an opinion on this subject and what caliber pistol works best in the street?
In the Marines I was taught shot placement ,shot placement so I am quite aware of accuracy & point shooting! This pistol will be used for home defense!
Think I'll have some coffee now-- Thank-you for your opinions & Semper Fi!
