Hi folks. Does anyone know of a drop-in grip safety for the Kimber Classic? I know what you're thinking- Kimbers come with beavertails. Truth be known, I just don't like the factory safety, and want to replace it with, say, a Brown "memory groove" or similar safety. Surprisingly, the Chip McCormick "extreme" grip safety is a no-go. Is the Kimber frame peculiar in any way, or should beavertails from Brown, Wilson, King's et al. drop right in? Thanks!
