Hi, I came across a video of a guy doing Walker mods. Some work, some don't. IMO a wannabe gunsmith. The video:
A few mods of his leave me cold:
A loose fitting brass arbor extension.
The replacement of the hand spring with a "ruger" type spring.
The washer under the bolt/trigger spring.
Notice the location of a house relative to his targets, minute 39:05.
IMO it won't be long before he sells his problem child to some poor unsuspecting newbie.
Regards,
Richard
