That new style of sight seems an improvement. The bright orange sticker on the one I had made precise aim needlessly dificult. The nice thing about the Mini-Master over the short barreled ones is you can actually hit stuff at a distance. A soda can at 20 yards is not safe. I recommend holding the gun with one hand and pressing the trigger with the finger of the off hand.

Is it possible to make a 5mm Rem Mag along the lines of the Mini Master?

The .25 ACP was developed because John Browning wanted to make a .22lr pistol that would feed reliably. Putting a .25 ACP in a revolver would be un-inventing the wheel.

Bump. At least a 3" would be cause for an immediate purchase.

According to NAA customer service: "The bore of the barrel is the same on all Black widows, it is the cylinders that have a different bore. "

I asked about Mini-Masters but I will consider it applies to all.

Do the different Mini Master models have different bore diameters? Is the diameter of the bore for the model with both cylinders different than those with one cylinder, either 22lr or 22 magnum?

Also, is there a significant difference between lr and magnum loads that tend to be most accurate? I have looked at the velocity numbers. I am not sure there is a significant advantage to the magnum cartridges in the short barrels.

Thanks!
