I also have a little problem with trigger reset when shooting slow double action. The remedy, in my case, was to wiggle the cylinder with the thumb of my support hand. Could be the gun needs a little more break in.
My Alfa has the reduced power mainspring and less than 200 rounds through it. It needs Federal ammo or primers to ignite reliably. It is also reliable with Winchester primers. Shooting double action pff hand at 15 meters, I could do 4 inch groups with my own cast Lee RN 124 grain bullet reloads. I'm sure groups will shrink with further load refinement.
I like the size of its frame and overall weight being similar to the S&W K-frame. I'll shoot a thousand rounds through it and if it holds up, ie, remains mechanically tight and retains its timing and accuracy, I'll declare it a proven firearm and will make it a keeper.
I like my Alfa as much as my 686-3 and GP100, both with stock springs.
