Nagant M1895 + Colt SAA + PB 6P9 + Zarona from darktide = this.
The Nagant’s sealed firing system meant that the Nagant revolver, unlike most other revolvers, could make effective use of a sound suppressor, and suppressors were sometimes fitted to it. In that respect (and a bit of design) this revolver is similar to the Nagant.
