The Winchester SXP Buck/Bird Combo is a pump-action shotgun in 20 gauge that ships with two barrels: a 26-inch vent-ribbed bird barrel and a 22-inch rifled deer barrel. Swapping barrels converts it between upland/waterfowl and deer duty. Both configurations use the same SXP pump action and 3-inch chamber.

Detailed Features 

The bird barrel has a vent rib for a consistent sight picture on moving targets and is compatible with the Invector-Plus choke system, which lets you change shot pattern density to match your quarry and distance. The deer barrel is rifled for slug accuracy and has an adjustable rear sight for ranging in different light conditions. 
 
At 6 lbs 8 oz (bird configuration), the SXP is light enough to carry comfortably over a full day of upland hunting without becoming a burden. 
 

Target Audience 

This combo suits hunters who pursue birds during one season and deer during another and don't want two separate guns. The 20-gauge recoil is manageable, which also makes it a reasonable choice for younger or recoil-sensitive hunters. 
 

Usage Scenarios 

• Bird Hunting: The 26-inch bird barrel with Invector-Plus chokes handles waterfowl and upland game. 
• Deer Hunting: The rifled 22-inch barrel with adjustable sights improves slug accuracy at typical deer distances. 
• General-Purpose: The pump reliability and matte finish hold up in field conditions.

The Winchester SXP Buck/Bird Combo in 20 gauge gets generally positive feedback, with a few consistent criticisms.

Versatility is the primary selling point owners mention. Having two barrels that convert the gun from bird to deer hunting in one package is valued by hunters who cover both seasons.

The pump action is routinely described as smooth and reliable. The SXP cycling speed is frequently noted as faster than competing pump designs, which is noticeable on fast-moving birds.

The 20-gauge recoil level suits hunters who find 12-gauge loads hard on the shoulder, including youth shooters. It is mentioned positively by owners who do high-round-count days in the field.

Recoil during extended sessions draws some comment even with 20-gauge. A minority of owners find it firmer than expected, though this is typically tied to specific heavy loads.

Fit and finish gets occasional criticism. Some owners note quality control inconsistencies on specific units, though overall reliability isn't called into question.

For the price, owners generally consider it a practical, capable hunting tool rather than a refined sporting gun. That expectation seems to align well with the SXP's actual character.
