Winchester SXP Marine Defender 12 Gauge Stainless/Silver Pump Shotgun

A: They won't fit they would need gunsmithed for this model. Other SXP models come with LPA Ghost Ring rear sight (insert), Winged fiber optic front sight

A: Jim, Winchester lists the trigger guard as (Trigger Guard Material Composite). Yes the Pistol Grip Stock is relatively easy to do with regular hand tools.

A: Hi Jim, the Receiver is made of a "Metal Alloy" and the trigger guard is a "Composite" Material and not metal. (http://www.winchesterguns.com/products/shotguns/sxp/SXP-Current-Products/sxp-marine-defender.html)

A: Yes Jim, the "Trigger Group" is made of metal and the Trigger Guard Material is Composite. http://www.winchesterguns.com/products/shotguns/sxp/SXP-Current-Products/sxp-marine-defender.html

A: parts in the trigger assembly are metal but the assembly itself is a polymer

A: Jim, this will depend on the mount type. A piece of masking tape will be some inexpensive insurance to help protect the sinish.

A: it would depend on the type mount. Electrical tape is better protection than masking tape

A: The stock is listed as (Stock: Synthetic) by Winchester.

A: Polymer synthetic stock.
