Hey guys,

I just started the paperwork on my CHP 4006TSW last night. If i recall correctly, my serial number is a 9xxx number.

I was wondering what are some of the things I should look for in terms of maintenance. I don't have much experience working on guns, but I'd like to keep this gun for a while.

Also, does anyone know if the 4006TSW parts are interchangeable with the original 4006? Do they use the same barrels/magazines/hammers/decockers etc?

Thanks!

I added a part commonality list to this thread:

The list is strictly based on part numbers, you may be able to fit parts that do not have identical part numbers.
