The OP did not list a particular gun model and any gun may have issues particular to the brand. I notice most nose dive problems occur on the first round, at least in my guns. In a 1911 9MM Colt a Kimber magazine provides a higher angle than my Springfield magazines. Much easier to use the Kimber magazine with hollow points. My RIA .45 will feed from a locked open slide better than when the slide is racked.
In my Kahr PM9 the slide has to be locked back and released to feed hollow points. If you try to rack the slide it will not feed. Instant nose dive.
The good thing about the Smith & Wesson autos is they never seem to have the problems of the Colts due to the intregal feed ramps.
If a magazine won't feed diassemble and clean first. Check the feed ramp for burrs or scratches and if all else fails try another magazine.
Just my .02
