I bought a P238 blackwood recently and the first thing I did was polish the feedramp and manually cycle the slide 500 times, in fact I do that with all my guns when I purchase them new. I've always been a "release the slide with lever" kinda a guy and I have had zero malfunctions through 250rds. I do use slide grease instead of oil on my Sigs, something I think they require.
