Yeah , if you removed the barrel once a year it'd be excessive . If you dropped it in the creek or got caught in a thunderstorm , sure but .... Any who ....lock out .... A finish nail with blunt tip and tap the pins out , slowly , carefully. The pins are supposed to go from lock side to S.P. side but I've seen some dumb stuff . ... tang screw out and holding barrel.in channel , tap heal of buttplate on the bench ...barrel breech pops out . I have to do this for each build 5000 f&%$ing times ! ( slight exaggeration for effect ) so its easily done when you get used to it but .... its entirely unnecessary unless something drastic has happened to the firearm or your just bored and curious . Just go slow and be careful , it'll be fine if you have to ....
