This is good info, as I was wondering about the grips on my 28-2. The target grips that came with the gun are well-used, the right panel dinged up much worse than the left, lots of embedded grime, and more than a few dings. The magnas I bought the other day are not as bad, but they had been sealed in shellac by a previous owner. I removed the shellac with acetone, smoothed them down with 0000 steel wool, and rubbed in a few coats of boiled linseed oil. The targets got the same treatment.

Anything else I should do to my grips?
