Agreed and my experience too. Before I put mine [Colt .38 Super] through it's first 2000 round test I figured out it liked to be well lubed. After watching a Larry Vickers you tube video where he actually submerged a DD AR 15 in motor oil then fired it successfully I decided I really couldn't over lube it within reason. So generous grease on the rails and barrel hood and Mobil 1 in other places. In addition, full power springs and no bunny fart loads.
But, if one takes a long time to do the test, as in months, the lube may dry out a little.
