Caring For Your Gun Grips Our wood grips are made from the highest quality California and European walnut blanks available on the market today. As with any wood product, it contains moisture, which can evaporate (dry out), and lead to cracking and "checking," if not properly sealed and cared for. We finish our grips with linseed oil, which is a standard practice in the industry, on almost all wood used in the firearms industry, including rifle stocks, which allows them to be modified, resanded, refinished, etc., in case you somehow damage them. This is not possible with the modern epoxy and resin types of finishes. Like any non-petroleum based wood finish, linseed oil tends to dissipate over time, and we highly recommend that a coat of either linseed oil or some other natural oil be reapplied if you notice the grips drying out, or turning a lighter color. This can be done with a brush or rag, and applied liberally, and allowed to dry or soak in. As an alternative, even using the "gun" oil, or lubricant that you use to lubricate your firearm is fine, and will NOT HURT the wood. This was common practice for many years, and can add a fine look of "age" to your grips, if you choose to do so.
