Jim Cirrillo was a NYPD stakeout squad cop back in the 60s. Was involved in more than 250 shootouts and survived, killed more people than any other cop.
His main weapon was a Smith Model 10, 38 Special. Not sure what loads but back then issue ammo was pretty anemic. I think he rolled his own but not sure.
250 shootouts ????? Come on man, Joe Biden tell you that story?
