Purchased a new R9 stainless yesterday.  my first.  Purchased to replace my primary pocket carry gun which was a LCP, which has served me well for the past year, but wanted more power.  Before buying this masterpiece I bought a diamondback db9.  Had problems, long story short after a replacement gun and still unreliable performance I had to return the db9.
Took the R9 to the range and fired approx 75 rounds.  What a weapon.  Solid construction, sharp recoiled, and very reliable with quality ammo.  I fired 36 rounds of PMC with no malfunctions, 24 rounds of WWB with two FTF.  7 Hornady CD, 7 Gold Dot 115, and 7 GD 124 with no malfunctions.  
The gun is unbelievably accurate.  I shot two separate 6 round groups with WWB at 7 yards LESS THAN 2"! 
I plan to carry speer GD 124, I'm sure there is a thread, I have not read the whole site yet, but i was wondering what ammo everyone suggests.
Thanks for any input 
very happy with this gun
