Nephew always borrows my 1978 standard model when he goes to range, so as he is 18 this month my brother and I were going to buy him his own .22 pistol. Turns out here in MA, all the MK3s and 22/45 models were removed from gun dealers stores, as the pistols are no longer MA compliant. I emailed Ruger customer service and a few days later, a rep called and told me the pistols are being redesigned, and therefore are no longer MA compliant. So here in MA, only the SR22 is the only Ruger .22 semi-auto that can be sold
