I have and do, but have run into problems; a Dan Wesson Supermag(no sideplate)trigger group comes out from below and requires 3 hands to replace. Brought it to a local gunsmith, who kept it for 2 weeks and ordered me a new hand spring after breaking the one it had, gave it back to me as I had brought it to him, finally talked to the DW smith and he talked me through reassembly, great people!!
I usually get a manuel with blow-up diagram of the gun and check if there are any websites/blogs specific to my gun, before opening now.
