It really depends on what sort of matches you end up shooting in. As far as a .45 goes, SIG makes a version of the P220 called the P220 Sport but you would want to buy it with the mods already made. I know where one is but it's not for sale :lol: and gunbroker/etc will have one occasionally. And there are some great wheel guns in .45 as well. I love the S&W Model 625. Good luck with the search!
