So I currently carry an LC9. However I've been wanting to get into something with a bit more capacity and heft to the round. I've debating between 40 s&w and 45 acp. If I go 45 I think the glock 30 (especially the model S if I can find it) would be perfect. I like that I can carry g21 mags as backups. However any other thoughts on the choice of cartridge or perhaps gun choice? Don't offer XDs I don't like them and never will. Just saying.
