I was wondering if someone may be able to help with a problem I have with my TX200 MKII. Basically I can cock the rifle but when I pull the trigger, nothing! I have to recock the rifle to be able to fire it, it does this regularly and is very annoying. What do you fine folks think the problem could be? Am I just being a cack handed fool and not cocking it properly? ( I'm right handed but shoot left handed and find it a bit of a pain in the arse if I'm honest). Thank you in advance for any advice you may be able to give.
