Weight and recoil come up first. At 6 lbs 12 oz, the SX4 is light for a semi-auto shotgun, and shooters report the 20 GA recoil is genuinely comfortable over long sessions. Both new and experienced shooters mention this as a strong point. Reliability is frequently praised. The gas-operated semi-auto action cycles cleanly with most 20 GA loads once the gun is properly cleaned and lubricated. Build quality gets positive marks. The matte black finish and synthetic stock hold up well in field conditions, and the chrome-lined bore is cited as a durability plus. Versatility with different choke and shot combinations comes up regularly. Waterfowlers and clay shooters alike appreciate the Invector-Plus system. Some users mention a break-in period with lighter target loads, where the action can be slightly sluggish until the gun wears in. A few also note that the factory choke selection is adequate but limited compared to aftermarket options. ## Pricing **4 offers available** | Vendor | Price | |--------|-------| | Grabagun Com | $907.99 | | Primaryarms Com | $929.99 | | Gunbuyer Com | $953.35 | | Guns Com | $986.99 | ## Similar Products - [Winchester SX4 Compact 12 GA Semi-Auto Shotgun, 28" Matte Black](https://gunsnation.com/p/winchester-sx4-compact-12-ga-semi-auto-shotgun-28-matte-black/UCr9whMK) - [Winchester SX4 12 GA Semi-Auto Shotgun - Matte Black, 4+1 RD](https://gunsnation.com/p/winchester-sx4-12-ga-semi-auto-shotgun-matte-black-4-1-rd/UCr9wemA) - [Winchester SX4 Compact 20GA Semi-Auto Shotgun - Matte Black](https://gunsnation.com/p/winchester-sx4-compact-20ga-semi-auto-shotgun-matte-black/UCr9whND) - [Winchester SX4 Compact 20GA Semi-Auto Shotgun - Matte Black Edition](https://gunsnation.com/p/winchester-sx4-compact-20ga-semi-auto-shotgun-matte-black-edition/UCr9whN6) - [Winchester SX4 Compact 12GA Semi-Auto Shotgun - Matte Black, 26" Barrel](https://gunsnation.com/p/winchester-sx4-compact-12ga-semi-auto-shotgun-matte-black-26-barrel/UCr9whMb) - [Winchester SX4 Compact 12GA Semi-Auto Shotgun - Matte Black Finish](https://gunsnation.com/p/winchester-sx4-compact-12ga-semi-auto-shotgun-matte-black-finish/UCr9whMi) --- *Data from [GunsNation](https://gunsnation.com)*
