The following procedure has worked well for me for the last 40 or so years.
New handgun: Field strip, clean, remove every trace of lubricant!
Take totaslly dry gun to range and fire at least 200-250 rounds. If no malfunctions of any kind, clean and properly lubricate, put it in my holster and trust it. It it fails, clean and run same tesat over again. If there are malfunctions during second test, trade gun away.
I believe in properly lubricating my guns, however I will not trust a gun that isn't 100 percent reliable with no lubricant at all.
