Sorry for hijacking the thread but I see you have a TX200hc in your signature.
I have recently bought a used lefty and after using it I think that a little more thought could have gone into the design. Whilst the loading port is cut out to the left side of the gun, the anti-beartrap release is on the right which is awkward as you use your right arm to cock it. The easiest way round this for me is to press the abt with my thumb whilst I use my middle finger to push the cocking lever past the notches and then close the lever as normal.
I wouldn't have thought that it would be too difficult to fit the abt on the left and machine the notches accordingly.
What are your thoughts?
