Here are some posts (on various forums) that I've used to decide what 9mm bullet weight to use:

• Concealed Carry - what weight
• M4Carbine - Service Pistol Duty
• M4Carbine - stickies in the Terminal Ballistic Information section

I personally go with 147 grain weight for the following reasons, in order:

• they are more accurate in my P99
• Remington Golden Saber's run flawlessly through my P99
• I can get good pricing per round on 50 count boxes of 147 grain Golden Saber

IMHO, each gun is going to have it's own "sweet spot" for ammo weight and performance. For me and my P99, I ran almost a thousand rounds through it before settling on my SD ammo. Soon I'll have a 9mm P99c AS, at which time I'll once again run through different ammo weights and brands to find it's sweet spot. I hope it's also 147 (simplifies ammo reloading / purchasing), but it may not be.

As always, YMMV - Fargazer
