I was having a problem with my primer slide assembly returning to battery, and I suspected that I'd simply worn out the little spring that pulls it back in after picking up the primer. I knew about their warranty but figured this wouldn't apply since springs wear out through normal use. I tried to find the part number but it was missing from their online schematic, so I sent them an email of inquiry. Their response was to ask for my address and told me no charge, including shipping.
What I received was not just one spring but two... and both a large and small primer charge bar, a primer washer (that sizable black plate under the charge bar) and various other primer parts. From what I can tell, it's about $60 worth of parts and shipping expense.
And all I asked for was $.50 spring!!!
Wow, I can't speak highly enough of those folks and their products!
