In public it's either a Ruger LCP with laserguard or Sig 938. I'm a big fan of 1911 style pistols mainly due to their triggers. I shoot rifles and revolvers with light triggers all year long and am more accurate with a good trigger. The LCP is a striker fired handgun and I can't shoot it as well, but still shoot it considerably better than what most consider necessary for a CC pistol.
I carry the 938 during cooler months where most people are wearing jackets and heavier clothing. It's both easier for me to conceal, and a more powerful round for penetrating layers of clothing and still offering good performance. I use Hornady Critical Defense ammo in both.
When traveling but not hunting I usually also take a full size 1911 45 and a darn good flashlight in case they are needed. Hope they never are, but I trust them more than my CC handgun when I'm in a home, hotel, or tent.
In the woods I mostly carry a 357 S&W 386XL Hunter when not carrying a rifle or shotgun. It weighs a little over 30oz with a 6" barrel and 7 shot cylinder. It weighs exactly the same as my Ruger SP101 4.2" barrel 5 shot revolver and is easier to shoot well. It is an extremely accurate gun, and the recoil is very mild with the grip they put on them. If I ever need it I have a Ruger Redhawk 5.5" 44 magnum with tritium sights and a Diamond D chest holster. I shoot it quite a bit but haven't been on a hunt where I need to carry it yet. I mostly rifle hunt and don't pack a handgun if I'm also packing a rifle. The 386 goes on scouting trips when not packing a rifle and no big bears are present.
Around home I have a few beat up Ruger P series handguns I picked up cheap over the years that reside in the vehicles. They are bulky but pretty accurate and very reliable. I live in a pretty rural area but also pretty close to a major highway. There have been enough times over the years people from the highway have showed up and created tense situations I like having one with me. I have never, and hope never to use one, but it's better to have it and never need it than the other way around.
Last fall we were eating supper with some elderly friends and a jeep Cherokee showed up loaded to the gills. The lady got out of the jeep and walked up to talk to our elderly friends that owned the place. She was wringing her hands, eyes unfocused, acted like she may be on drugs. She said her boyfriend in the jeep with her was abusive and that she needed help, but didn't want to call the police. He got out of the car and came up and apologized, said she was off her meds, and then she jumped in the jeep and left him. He started walking after her. They called the law and they picked him up, turned out he was right. A situation where being armed was not necessary but I was sure glad I was, you never know what to believe or what might happen.
