This is not an arguement over a handgun vs shotgun, right or wrong, I prefer a handgun for home defense for my own reasons. What I am struggling with is should it be a revolver or pistol? I have a S&W M&P 9mm compact that used to be my conceal carry. I have found another gun for that purpose now. I'm trying to decide if I want to use this pistol as my main home defense gun. I was always a revolver guy, and although it is possible to have a malfunction with a revolver, I feel it is much more reliable than a pistol. With that said, it is hard to argue the magazine capacity (firepower) of a pistol. In the case of my M&P 12 and 17 round magazines. I am on the "fencepost" on whether I will keep the 9mm or sell it and purchase a revolver. I used to own a Ruger Gp100 357 but traded it a couple years ago. I do miss it. You can't argue the knockdown power of a 357 magnum. I would not shoot it for years but it would always go "bang" I have thought about the 8 shot S&W 357 although expensive does give me more capacity. I am looking for something that I can put away loaded in my lockbox and forget about it until needed. When I do need it, I want it to work. With a revolver you don't have to worry about getting that cartridge from the magazine to the barrel. It is already there and ready to go. I am concerned about the magazine spring in a pistol. I have searched the internet and get various opinions on spring life. I have emailed Ruger, S&W, Springfield and all of them replied back that they do not recommend leaving a magazine loaded for a long period of time due to spring setting. They recommend checking the spring length periodically and rotating magazines. But can't get a clear answer of how often. Will the oil on the slide rails gum up over time? With all the other things around the house to maintain, do I want to add something else? I took my pistol out to the range the other day and purposely tried to "limp wrist" it by hold it low on the grip and allowing it to recoil up. It did "stovepipe" on me 2 of the 3 shots. So now if I'm hiding behind cover and reaching around, will the same thing happen? Looking at the revolver, if 3 "bad guys" come knocking down my door, will a six shot be enough? I would much rather have the higher capacity at that time. Not sure if there is a clear answer on this subject, but just looking for your thoughts and opinions.
