One of the other guys (younger instructor, still in his "acquisition"stage of life

) picked up a M&P9 Pro 5" sometime last Fall. He's owns a few M&P's and Glocks, and just trd off an older M&9 VTAC before getting another standard M&P9 & the Pro 5".
Anyway, I tried his new Pro 5" with our standard 124gr +P duty ammo, and it not only was a tack-driver, but the trigger was smooth, light-feeling and had a clean break. I didn't pay any attention to the loudness of the mechanical reset, as I'm a longtime trigger recovery shooter for defensive application. I save the shoot-to-reset for leisurely, unhurried target shooting.
I didn't have a gauge with me, but the way his trigger felt it could've easily been at the lighter end of the normal range for the 5" 9Pro, which is listed at 4 - 5 1/2 lbs on their website (never got the engineering specs for other than the standard models).
It felt better to me (and him) than one of his other M&9's (that he only uses for range enjoyment) in which he'd previously installed the popular aftermarket parts.
The newer stock M&P 9/40's have been feeling good, though,as I've randomly sampled new ones we've received for duty issue. I let them grab me a boxed M&P40 off the top of a stack of new ones for my new duty weapon.
It was virtually bone dry (which struck me as odd, considering the guns saturated with packaging oil I've seen over the years

), as were the mags. I gave it a quick visual inspection and took it downrange, where Ir an 160-odd rounds through it (mix of 180gr ball & one of the current duty loads), and then took it back the next day to run another 100-odd rounds of some more ball and this time some mixed JHP's we've used.
The M&P40 fed fired everything with equal aplomb and monotony, and it produced fast, tight groupings. No sight adjustments. I finished the second day by making a few called hits on staggered wooden clothespins pinned to the target cardboards out at 5-7+ yds.
Good enough for gov work, I'd think.
I actually like the overall grip (using small insert) better than either my M&P40c or my M&P45 FS w/manual safeties. Significantly better grip ergos than my SW9940, too.
Not bad.
I'd have taken a M&P9, but they've become more popular than expected as the 9's, .40's & .45's were rolled out for issuance. I thought it'd be more appropriate if I left what remains of them for any guys or gals who are working full time and who want/need a 9 instead of a .40/.45
FWIW, the M&P40 is one of the softest shooting .40's I've ever used, owned or tried. The M&P9 Pro 5" reminded me of shooting a K-frame competition gun firing something between target wadcutters, and the standard M&P9 using 130gr ball. Very nice.
