Kimber or if you can afford the extra $$, an STI Trojan single stack or an STI/SV limited gun. You can shoot Limited 10 with a single stack and not suffer any significant disadvantage due to mag capacity. Though Scooter is right that a wide body will reload easier. People can reload a single stack real fast if they want to learn though.
A Para will not hold up under heavy IPSC use without replacing literally most of the parts.
I had a Para, have Kimbers and STIs and the while the Para served the purpose to get me to a B card, parts failures were frequent. About 8 regular shooters in my club also bought P16s and P16 Limited and had similar experiences, some worse - some better, but in the 6 or so years I've been active in IPSC, Paras seem to break at a rate far higher than other guns.
