Consider S&W third-gens, they're pretty much entirely made of stainless steel, and come apart even easier than a glock. They are very accurate, durable due to being built like tanks, quite rugged, and they are as reliable as glocks as well with all different types of ammo. Someone might bring up the fact that they are heavier than other guns, but a proper belt and holster take weight right out of the carry equation, while weight definitely helps absorb recoil upon firing. I actually prefer heavy guns, especially for CCW, my Desantis belt makes it no issue. Check out the 3913 or 669 if you're looking for something compact.
