Like many have reported with their own guns, my full size M&P9 is feeble at throwing brass and was pelting me with casings every fourth round. Several suggested that the 115gr. UMC I use at the range 99% of the time was a light load and partly responsible for the problem. Well, it's not cost effective to shoot 124 or 147gr. FMJ if you can even find it, so I plunked down the $33 (shipped) for a stainless guide rod and 11# recoil spring from Speed Shooter Specialties, who btw provides prompt turnaround and very good service. Installed both items and sent 150 of the same rounds down-range. 8) While it didn't totally cure the problem or turn the gun into a mad flinger of brass, the casings were at least kicking clear of me and reduced the problem to getting hit with a casing every 35-50 rounds. That's a much more tolerable frequency, so I'll use this setup at the range from now on. I was a little concerned that the lighter spring has a noticeable pause before the slide goes all the way into battery. It always goes bang, no failures. There's just a slight hesitation. I'm curious if splitting the difference and going with a 13# will result in a more-positive snap into battery and still throw brass clear. I guess for a mere $9 plus shipping, I can find out, huh? :wink:
