Razorwind:
Having cranked innumerate rounds through the "990" over the past 5 years, I can testify that it is a strong, accurate and utterly reliable gun. During this timeframe I have not had a single failure to feed and none of my peers have either. However, though I have complete faith in it my objective is to have similar faith in something a little less irritating to use when the time(s) come to lock the slide back, switch magazines, etc.
This past year the "Production" class at my IPSC club was dominated by the S&W M&P which is prompting me to give it a long look. Aesthetically, it looks very similar to the 990 but the trigger pull is considerably lighter and the requisite knobs are in the right place.
Anyway, I am still looking for the "right" gun too, and if the M&P isn't it I'll keep looking.
