After shooting a few events with my power grip, I was finding that the focus on my camera was having some intermittent issues with not being able to lock focus on a target. I seemed like the harder I gripped the camera the worse it got...then I noticed the base of my right hand...as I would grip the camera to focus the base of my hand would accidentally press against the other shutter button. Now I know why those darn grips have a lock button...doh! Lock on, no issues, problem solved.

Funny and glad you figured it out. Thank you for sharing!
Ideally, the LEFT hand should be supporting the weight of camera and lens during shutter release, while the right hand remains relaxed, touching the camera just enough to keep balance. A relaxed hand will yield a smoother triggering of the shutter button compared to a tense, gripping hand. Unfortunately, modern DSLR body design practically encourages the bad habit of gripping the camera tightly with the right hand. Before the days of electronic stabilization, holding a camera correctly was a must to avoid capturing images blurred by camera shake.

I use a wrist strap with my 300s and D800 .... both with battery grips .... sometimes when I check my in camera photos ..... I have many photos of the ground or my leg .... it is always because I accidently turned the grip shutter on .... never got a useable picture

I see what you mean about the shutter lock. The placement on yours must be very different. I never had that problem with my Pentax K-20D Battery Grip. But it does have a lock on the (portrait format shutter release). But I do have a problem with my auto-focus lenses when shooting auto-focus. I'm so old school manual that I keep grasping the lens around its grip and thus stopping it from auto-focusing. Duh! I mainly use old "film" prime lenses.
