Detailed Features 

 
The AccuTrigger adjusts pull weight from 1.5 to 6 lbs, which is the key functional feature on any Savage rifle or shotgun. A crisp, light pull directly improves slug accuracy. The thumbhole stock provides a stable grip for shooting off a bench or rest, and the laminate handles temperature and humidity changes better than traditional walnut. 
 
The 20-gauge bore is a practical choice for a slug gun: lighter recoil than a 12, still effective to 150 yards with the right sabot slug, and common enough that ammunition is readily available. The matte finish on both wood and barrel reduces glare in the field.

Owners of the 220 Thumbhole tend to be hunters who want a dedicated slug gun and aren't interested in a general-purpose shotgun. Accuracy and the AccuTrigger get the most praise. The gun shoots well at 100 yards once dialed in with the right sabot slug. The thumbhole stock is frequently called out as genuinely improving stability, not just a cosmetic choice.

Criticism is fairly mild. Some buyers note the 2+1 capacity is limiting and the gun is heavier than a field gun they'd carry all day. Shooters coming from semi-automatics mention the bolt-action handling requires adjustment. A few also note that the optic-only setup means you need to commit to a scope before it's field-ready, adding to the upfront cost.
