Well, for bear and in .45 I'd recommend a Les Baer in (or 10mm).
Whatever gun you get though make sure you dry fire a ton and practice live fire as well. I would also take some competent training to get you started right.
I dry fire every day and shoot 50K+ rounds a year between training and USPSA/IPSC matches I can't emphasize enough the value of proper formal training so you can practice correct techniques. A trip here for a 3 day handgun mastery course would be well worth it. https://tacticalperformancecenter.com/
