The pistol does need to be properly lubricated, although not necessarily "wet." You cannot "limp wrist" a pistol this small...the recoil must be controlled by the shooter to allow proper function. I agree that you should try speer gold dots as the most likely ammo to function predictably...some of the R9's are ammo sensitive. I have noted some wear on the inside of the slide at the takedown pin hole on my Covert, but it has caused no issues and has not gotten worse after the break in period (about 50 rounds or so), and this has been discussed/noted on at least one other thread in the past 6 months. The first few times you fire it and clean it you will note metal filings from the break in period....these can cause issues at first also...take it down, clean it well, shoot it again. Mine had a few issues to begin with, but is now my primary carry piece and it seems to work without fail.
