Hi folks,I`m totally new to .45 cal. handguns and have just purchased a model 36. Can anyone tell me the best self defense round for this handgun? I bought some 165 gr.Powerball +p when I bought the gun and I was wondering what is really best.It seems that all the ballistic tests used a 5 inch barrel and as the 36 has a 3.78 in. barrel,I was wondering what was the best round.Any suggestions? Thanks to all.
