PC Single Action Half Cock Hammer & Trigger Kits for Ruger® SA [PC-REV-012]
$199.95
I ordered 3 of these-one for an older model Vaquero--one for a new model Vaquero and one for a single six 22 cal.ruger--all work perfectly and only took a few minutes to install if your familiar with the inner working of a ruger--also communication is excellent as well as shipping---Paul
