I built a .410 last year wanting the smallest lightest little single shot I could find but 28 ga is by far my favorite turkey round.

I really like the Mossberg SA line, available in 12ga, 20ga, 28ga, .410)

The Viper G2 and the SA line are essentially the same guns. They were manufactured in the same plant, numbered, stamped with different company names and built in Turkey. The vast majority of parts and internals for both brands are reportedly interchangeable
