I test fired my charco 38special revolver after having the firing pin replaced...it digested all 50 rounds....however , I experienced problems in the cycling? rather the revolving of the cylinder/chamber?(Pardon my description, am a newbie in revolvers).The gun would sort of get stucked up from time to time( I would pull the trigger and would not be able to do so..it would be so hard...could not cock the hammer with my hand...What I did was to open the latch and and bring out the cylinder and then re insert it and tried to fire it again..sometimes the trigger would become operational and am able to fire...sometimes the trigger would not budge and the cylinder refuses to revolve in order to fire the gun...I hope you guys understood my explanation of my problem...Hoping for your kind assistance and advise...Thank to you all in advanced..best from Manila..Clarence
