Skans- I could hear a little "click" when I pulled the trigger. Not as loud as the "click" when its dry fired though. As stiff and gritty as the hammer felt when I took the gun apart before I cleaned it, I believe it was my problem. It freed up ALOT after spraying it with gunscrubber and working it back and forth several times. I'll shoot it later this evening to be sure.
Cajunbass- I've got the exact same model as yours. Mine is about to have a Tru-glo open red dot and Hogue grips. Do you like the BSA you have on yours? I have that same sight on a shotgun and I thought about putting it on my mk III but I was afraid it would be too bulky. Looks good on yours though.
