I only have one gun with disc set strikers. The tool is very well fitted, and looks like a screw driver with three little pins on the end, instead of a blade. The strikers are spring loaded against the disc, and don't hang up in the primers. Either disc is easily serviced anywhere the tool and a spare pin happen to be (usually in my glove box). It is a slick deal, with one of the three holes that match the tool having a witness mark, that tells you how far to turn it in. If one needed a vise to hold the action, one screwed it in way too tight.
I could service them in the dark, with the light from a match.
I have ventured away from spare guns since the meth craze started to blow hard-hunters vehicles make tempting targets in rural areas. Oh, there is a spare S&W 360 PD Chief's Special Airweight along any time I leave the house, and especially when I hunt in Pine or Aiken counties, but, it is in my waist holster.
I haven't found any of the listed American doubles to be really trouble free guns, either, by the way. Some have.
Best,
Ted
