The VT version of the Ruger Mk II does have an adjustable two-stage trigger. My pard's gun came from the factory with it perfectly adjusted, 2nd stage 2.5 lbs and no backlash or 2nd stage creep. Ruger discourages your messing with their triggers due to liability questions, but it is possible to adjust the old 77's (ones with the tang safety) and the VT (dark stainless HB laminated.) The standard Mk II trigger has the same adjustment capabilities as a standard crowbar, i.e.: none.
If they take our guns, I intend to let my hair grow long and acquire the jawbone of an ass.
