Brent,

If you're placing an order with an Authorized Randall Dealer or the Shop, the free spacers are:
1. Red-White-Blue the standard for most models, excluding full-tang like the 14,15,16 & 28, for example. You do not have to request it.
2. All-Red spacers
3. All-Black spacers

Chargeable Spacers are $25.00. Four choices
1. Aluminum & Black Spacers
2. Aluminum & Red Spacers
3. Brass & Black Spacers
4. Brass & Red Spacers

Regarding switching out standard handle material on a model,

The Captain can clarify my thinking. If the model's standard handle material, in this case, stag @ $70, is more than the replacement choice, Micarta @ $50, in this case, there is no charge. If it were in the reverse, the replacement would be a chargeable option and count on the five option limit, I THINK.

This rule excludes the full-tang models, of course.

Pictured here is a Sergeant's Model with all-black spacers, coupled with desert ironwood from the Shop. Gone but not forgotten.
