M&P 9 ammo question

[pingpong]

I've had no problems with WWB, Federal, AE, UMC, or Fiocci.

However, I've had reloads that wouldn't chamber. I'd have to whack it out from the other end of the barrel with a screwdriver, but the same round is fine in my XD and Sig. Gives me the impression that the chamber is a tad tighter than on other guns.

I have 2,000 through mine and have settled on two being the most accurate and having a nice sharp recoil that I enjoy...Magtech 115 FMC, being clean, accurate and just a blast to feel...Sellier and Bellot 115 FMJ being the most accurate, and being clean and slightly less recoil...this is the best 9mm I have ever owned and a joy to shoot...this is one gun I will never sell.
