I have friends to crash with in the Tampa area and I have shot with the Florida West Coast Defensive Pistol Club on a number of occasions. They used to use a range in Ruskin but now shoot on the Wyoming Antelope Club in Clearwater. I shot the Florida State IDPA there in February. WAC hosts both IDPA and USPSA/IPSC
Monthly club match fees are $10- $15 at the places I shoot.
Most individual matches are open and you do not have to be a club member. You are supposed to only get one match in IDPA before being required to join the national organization but a lot of places are not real strict on that with their cheapskates.
