Detailed Features 

The break-open action loads and unloads quickly with no moving parts beyond the hinge. At 5.4 lbs, it's light enough for youth shooters and older hunters who want a gun that doesn't fatigue on a long walk. The recoil pad absorbs some of the snap from 20-gauge loads. The modified choke tube gives a mid-range pattern suitable for upland birds and small game. Disassembly for cleaning is straightforward.

The Savage M301 in 20 gauge gets a straightforward response from owners -- it's a budget-priced single-shot that does what it's supposed to.

Affordability is the most common positive comment. Buyers frequently recommend it as a first shotgun or as a utilitarian option for occasional use. The lightweight build is appreciated for carrying during hunts, and the simple break-action operation makes it accessible for newer shooters.

The negatives are predictable for a lightweight single-shot 20 gauge: recoil is sharper than some users expect, especially during extended range sessions. A small number of users find the trigger pull heavier than they prefer. The lack of adjustable chokes or upgraded sights limits versatility compared to over/under or pump options at higher price points. Aftermarket accessory availability is limited.

Overall the gun fits its intended market -- entry-level and light use -- without pretending to be more.
