Yes, I do it now with the 40c.  It's perfect.  Not one malfunction and such a better shot with it.  About to start a "2-gun" match with it and my AR.     
    
I can't get to a site now to get the actual type, but i'll describe it.  Not a stovepipe.  It's the one where it feeds a rd into the chamber and the slide is slightly back where I can see it.  Then it appears it's trying to insert another rd.  I was told to try diff mags.  I bought a couple more Kimber mags.  Then I tried two Wilson mags....Same.   I was then told I need to hold it differently...go figure.  Same.  It was a quick drop the mag....rack, rack....insert mag, rack...back in the game.
