Like many I'm always trying to get the exact setup I want for CCW. After several drawer fulls of holsters and just as many pistols, I have finally narrowed it down. Full size Smith and Wesson M&P 9mm with thumb safety (only one side) with Crimson Trace in a IWB Crossbreed holster. (one of the ugliest but most comfortable holsters), carrying one back up magazine. Plenty of ammo, cost of ammo is where I can still shoot and practice, quality self defense ammo carried, can shoot pistol one handed if needed, quick follow up shoots, low recoil, pistol is light weight and accurate.
