I just swapped a 1914 commercial Colt New Service in .455 for a blued VG/Exc pinned/recessed Combat Masterpiece c/w original box plus cash.
Always wanted one back in the day. It has Magna grips, wide trigger and hammer. I'll likely grind down the trigger or replacement it with a smooth combat trigger.
I've got black hard Safariland 'coke bottle' grips for it. I find the Magnas useless for any purpose.
