I started shooting a few years back with my XD9. I have recently purchased a Sig mosquito .22lr and a Kahr CW40. I really wish I would have started out shooting the .22 because I can go to the range and shoot for hours and spend very little on ammo. I shoot CCI mini-mags which are about $7 per 100 rounds and it is a blast. Now that I am more comfortable with my shooting skill moving up in calibers is easy.
