If you're looking for a .44 mag handgun, why wouldn't you just buy one of the many revolvers made in that chambering? Just curious.
Not the OP.
I once had an Encore in 44. At the time, the reasons I sought one out and bought it, as opposed to another revolver, were:
1. Simplicity of a single shot. Break open, fewer parts, easier cleaning. Quicker, easier load/unload process.
2. 10" Encore is about the same overall length as a 7.5" SBH. Longer barrel, higher velocity.
3. No b/c gap. Theoretically higher velocities, also eliminates chamber misalignment possible with revolvers.
4. Easier to mount an optic.
Downside and the reason I sold it? Way too big and heavy for a 44.
All the qualities it possessed were real, but for me the size/weight of the gun outweighed those positives.
