I am a cilvilian who has a 40 S&W MP for home/personal protection. I have been on the forum and just poking around got some gold saber 165 grain HP for my protection ammo. I just had a friend get a glock 40 and we went out shooting for the first time. When I asked him what he was going to use for his personal protection ammo he brought out the 180 grain JHP remmington UMC he got at Wall-Mart for 26$ for 100. He said that he did not think that it mattered that much and the guy at Bass Pro said they where the same thing as the Gold Sabers. Now this is from a guy that gives every one at deer camp a hard time if they are not using top of the line bullets for deer, but I can not get it through his head that there is also a difference it pistol ammunition. Any help of resource material would be appreciated. Thanks in advance.
