Took my sons ruger 44 carbine down for full cleaning last night. That's not a user-friendly rifle to disassemble to get to the gas tube and bolt assembly. You tube is asweome.....unless of course you remove the wrong pin. I popped out the pin that the trigger pivots on instead of the pin that holds the trigger group in. The second that pin came put I knew it was the wrong one because the trigger dropped free and I heard a pop. Shit. Spent half hour looking at a schematic I downloaded and couldn't figure it out. Oh well. Rifles perfectly clean but ill be taking a drive with the trigger assembly in a box to the local shop today to pay a Smith to put it back together.
