If you want a small pistol with a lil more power than that keltec, I cant recommend the bodyguard 2.0 enough. It seems so small, but just has the best grip out of small sub 9mm caliber handgun I can imagine. You can get this gun so low in your hand and with the bore axis so low, it has nearly no recoil and a great trigger. A step up from that I would recommend a shield of any kind, but if capacity is an issue for you then I'd get the plus. a step up from that, the 2.0 compact with interchangable backstraps is the best feeling handgun I've ever held. the shield and compact being optic's ready is huge too. Great triggers on all and all concealable. Then for home defense, you could use the 13rd in the shield or a 17rd in the compact to make it a full size handgun. but then again, I'm a smith and wesson guy who thinks glocks grip angle, grip shape, and texture are subpar. you can get a really comfortable grip sleeve for a shield 2.0 as well.
