Thats a good point Dave and I had not thought of that even though I use my half cock position with a loaded gun all the time while hunting. I will confess that I have never handled a gun with that safety feature so have no on hand experience with them.
The Henry barreled Whitworth semi military match rifle I shot for 11 years had a sliding safety..
It worked fine (I suppose) but there was NO real need for it and I turned down requests for them
on new locks.
As for the size of Jim Kibler's new flintlock if used on a 12 bore rifle ,Lynton McKenzie and Steve Alexander
made a copy on Lynton's 16 bore English target rifle and it used a tiny lock as found on a pocket pistol.
The gun was made by Fenton and had double set triggers which are NOT common on English guns of
any type.I have made two of these tiny locks and will not even consider a 3rd one now. I think TRS had
this lock as a kit and may still have if anyone wants to tackle it. It's TRS catalog #599.
Jim and Katherine should be commended for this endeavor and the major upgrade in quality in gun locks.
