FAQ
What makes the Winchester SXP faster than other pumps?
The SXP uses an inertia-assisted back-boring system that helps drive the bolt rearward during cycling. This reduces the force required to pump the action and allows for faster follow-up shots compared to a traditional pump. It is a mechanical advantage built into the design, not just marketing.
What magazine extensions fit the Winchester SXP?
The Winchester SXP uses a specific magazine tube design. Extensions must be SXP-compatible. We carry SXP extensions where available. The aftermarket is smaller than Remington 870 or Mossberg 500, but the key upgrades are available. Always replace the spring when extending the tube.
Is the Winchester SXP compatible with Winchester Model 1300 parts?
The SXP and Model 1300 share some design similarities but are not fully parts-compatible. The SXP is a modernized evolution of the 1300 design with updated dimensions. Verify any accessory is specifically listed for the SXP before purchasing.
What configurations is the Winchester SXP available in?
The SXP is available in field, waterfowl, turkey, and defender configurations with barrel lengths ranging from 18 inches to 28 inches. The Defender configuration is popular for home defense applications. Most accessories are compatible across SXP configurations, but barrel-specific parts (chokes, extensions) depend on your barrel length.
