I have short stubby fingers so I went with the smallest backstrap. That option was the biggest seller for me. IMO if a pistol doesn't fit comfortably in your hand then you should keep looking. Of coarse that only goes for your primary. I also think we would be remiss If we didn't take the oppertunity to own several other types of handguns, you know so we can be well rounded. For what it's worth my wife just doesn't see that as a good excuse. LOL
