This right here . Boom. Internet high five .I understand that for a professional or say a competition shooter a more expensive weapon tuned to their needs would give that person an edge. As for me I shoot a lot for a typical law enforcement guy but nowhere near the amount of a competitive shooter. For myself I do not believe a more expensive handgun would give me much more of an edge.
I do not take it as a knock at all. Like I said I am carrying what works best for me. I carry a Glock at work and the Shield is similar enough in function that I carry it as a back up. I just never liked the 43.
I also have nothing against someone that wants to carry a nice custom pistol. If that is what that person is comfortable with then I have no issues at all with it.
