I was looking to get the S&W 1911PD 4 1/4" to use as my concealed, but it does not come with an ambi-safety. Does anyone know if this gun can be outfitted for a lefty and if so what is that best to use. I don't know if this makes a difference but I was looking at the Crimson Lasergrip model which might be a problem if the grip needs to be modified at all. I really like this model so any suggestions would be great!
