I would dearly love to say one of my beloved S&Ws or 1911s. Perhaps even a classic PP/K but due to the high acid content in my skin none of them are really a go-to, Ill remove bluing and eventually pit stainless in the form of my grip. Secondarily I have a fear of employing one of them to save my bacon and having it impounded only to have it possibly returned in shameful condition, if at all.
I bow in shame to admit I was actually glad when the Tupperware guns came around. As long as I don't handle the slides much or forget to wipe them down every couple days I cannot harm them.
If I didn't have this inherited condition Id easily be happy with a 4 inch model 29.
My go-to is a H&K VP-9.
