how do you grip your 1911?

[masakari]

I use the high crossed thumbs technique with my thumbs atop the manual safety, as I have for years.
Like this:

I never had an issue until I started shooting aluminum 1911s and the extra recoil made my left (non dominant) thumb slip forwards and bump the slide release slightly, occasionally causing failures to lock back on the last round. I remedied this by loosening my left thumb's grip and relaxing it. It seems to be fine now, but in moments of stress sometimes my grip returns to its old state. I also sometimes feel like my thumb is uselessly dangling there.
I dont want to completely change my grip and use thumbs forwards as it doesnt really work with every type of pistol, and I absolutely must maintain my dominant thumb on the manual safety.
so the question is, how do yall hold your 1911? pictures?
