I would strongly recommend against Alien Gear. My OWB was floppy and loose fitting to my body and the IWB clips would slide around or come loose from my belt. I recommend Winthrop OWB holsters, Crossbreed IWB, or a high quality leather from Mitch Rosen or similar. Get a good gun belt. Very important. They will wear out so you'll need a new one every couple years. Comptac makes a good one. Carry a flashlight. You cannot shoot what you cannot see. Fenix lighting.
It takes a couple months to get really comfortable carrying everywhere. The holster and clothes you choose will morph until you're dialed in. I feel sloppy in an untucked shirt so I often wear a light jacket to conceal my OWB, mag pouch, and flashlight.
