Frequently Asked Questions
Are Winchester SX4 shotguns any good?
Yes – as an FFL who’s handled hundreds, the SX4 offers excellent reliability for the price. The gas system cycles light target loads better than many competitors.
Can a Winchester SX4 shoot slugs?
With the right choke (Improved Cylinder recommended), yes. However, it’s not optimized for slugs like a dedicated slug gun would be.
Where can I buy Winchester shotguns online?
Kansas Gunshop (kansas-gunshop.com) carries the full Winchester lineup with same-day shipping from Kansas.
What’s the difference between SX4 and SX3?
The SX4 improved the gas system and reduced weight. We find it cycles more reliably with light loads than the older SX3.
How many shells does it hold?
4+1 capacity with the included plug for migratory bird hunting compliance.
Is the walnut stock finished?
Yes – it has a satin finish that protects the wood while maintaining the classic look.
What chokes come with it?
This Upland model comes with a fixed Modified choke – ideal for pheasant and quail at medium ranges.
