Hello everybody. Thought I introduce myself, straight from Lynnwood. I am really eager to learn as much as I can on firearms them to better prepare myself and knowing what they are all about. I went shooting the other day with my Father-in-law and soon to be brother-in-law at Wades range. Rented out all the handguns they had in 9mm and .40. It was a blast. Trying to figure what would be best for me on a concealed. Any input would be great on any of your experiences. I was also wondering, Is it possible to convert a 9mm to a .40 or .45? I will do some more research but if anybody can point me in the right direction would be great.
