Join the queue of wannabe photogs making a $$ or two. There are sites that take your pix and list them along with millions of others and If they sell an image or two you will get a few cents as part of the 'stock photo' collection. You need to upload many pics to these to make a return and they have to be good.
If you actually want to make money at it you (a) have to be darn good and recognised as a gun photog and (b) specialise in something that people want or is unique in some fashion. Ideally for those you have your own website.
I looked into this when I was doing Motorsports Pix ( you needed a connection with a Car magazine for that ) and when I was about to be made redundant and my employment options were rather limited.
With retirement a not too distant prospect I have refined my chosen direction now so hopefully it will keep me entertained, busy and make a few $$ in the long run.
It is not an easy path to $$ I can say.
(Fortunately I was offered my old job back via the outsourcing company so didn't lose too much, only 30% of my previous salary
)
