Coyote,
I carried a Kimber TLE at work for years and used it for WB. It was originally equipped with an extended safety which I had changed to a standard non extended style. Since I retired I purchased a Remington R1 Carry and have changed it from the extended ambi safety to a standard style. I have never had much of a problem having a safety actuate but being I carried them cocked and locked while at work and CC I had them disengage while carrying them ... totally unacceptable.
I also concur about pulling it off and adjusting the detent depth so it engages to your liking.
Hope this helps.
