Bought a spending 1911 threaded barrel to replace the stock barrel in my Springfield and the Stormlake does not come with the pin/pivot installed. Maybe there is a reason for that, but for what you spend I'd think it would be there and you wouldn't have to get a drift punch out to change barrels back and forth . Anyway, this pin does not want to come out and before I beat it to death is there some trick? Left to right, heat it up first? Even a steel punch and hammer isn't getting it done.
