I agree with jsn: A lubricant, such as Breakfree CLP, does not dry out; it has soaked into the metal. It is still there to protect and lubricate the moving parts. On an autoloader, you can probably run a hundred rounds through a "dry" pistol before any malfunctions may occur.
Nevertheless, a dab of grease on the rails, the barrel hood, and on the front top tip of the barrel will work well to keep the pistol functioning properly. I like Synthetic All-Weather High-Tech Grease by Shooter's Choice. It works in wide temperature ranges. A little goes a long way.
Over-lubrication attracts dirt and dust and will jam a pistol. Another product I've been using is Militec-1. It is a durable lubricant that stays where you put it, which is unusual for an oil.
About Breakfree CLP: I have found that this product will "sweat out" on a pistol that has been in storage for a while. You have to wipe the weapon down from time to time to keep it from getting too gunky. G-96 CLP is less messy in this regard and has a better odor. Both products provide long term protection and lubrication on firearms.
Bill Laughridge at Cylinder and Slide has a good brochure on proper lubrication of pistols and revolvers. I recommend it. He advises, when shooting an autoloader at the range, to field strip it every couple of hundred rounds, wipe it down, and re-oil it sparingly. This procedure is probably best for tightly-fitted autos. Also, he advises inspecting a pistol that has been stored for a while to ensure it is lubricated properly before taking it out for a shooting session.
For daily carry, I would prefer to have a pistol that is slightly "dry" since dirt and dust is a concern. But for a range visit, I usually drop a bit of Militec-1 in critical areas before and during high volume practice.
