I'm still waiting on my Wilson Combat mags to arrive. I've always heard and read that WC's are really good. Sometimes ammo not feeding properly or slide sometimes not locking back with some brands have been fixed by using these mags. I'd go with Wilson's.
My Valor came with and runs fine on Metalform flush fit 9 round mags. Check-Mate and Ed Brown (Check-Mate) work equally well in all my other 1911 9mm.
Sorry....my bad, no experience with officer 8 round mags. I'll stick my neck out and say I have had no issues with Mec-Gar mags in my Springfield EMP and I do know they make 8 round officer mags in 9mm.
