It was hard to find in August 2026, in stock on only 8 of the 14 days we checked, and today the one retailer we track has it in stock. Prices barely moved in August 2026, holding around $325.30, so there haven't been real sales lately. Buying today, the lowest price is $325.30 at Classic Firearms, which matches the best price we saw in August.
