Just picked my New Special Forces. This is the older 5 inch version with the original Scallop style treatment. I'll be using it as my duty gun so started the test firing today with 100rds of ball. So far no issues not one using Wilson 47d mags. This is going to be a good one!! Anyone know what weight recoil spring comes standard? I assume either 16.5 or 18 but I can't find the answer anywhere. Thanks!
