Welcome. If you like the ergo of the P30 then the logical choice would be the little brother P30SK, however if you are planning to put an extended mag then try carrying the P30 instead since it is only half an inch that you'll be shaving off from the standard size mag.
Try the P2000 since it is just a tad smaller than the P30 but with the grip like USP/C or the P2000SK. Also the USPC is worth mentioning. I know you said that you are not a collector but that's how many of us start at first lol.
Wearing a good belt is one of the most important factors when CCW. I really like BigFoot Gun belts.
Good luck and let us know what you decide.
