For anyone out there that has a Hatsan Bullboss in .25 cal I've seen references to the hammer spring backing off as it is fired. I saw a post about applying locktite to the striker nut to stop the problem. Has anyone done this tho their Bullboss and what were the results. I've also noticed the a the spring is tightened the sear doesn't want to engage. I thought I might look for some input before opening mine up to do some deep cleaning and deburring. Thanks in advance for your help.
