Pulled the side plate today and cleaned up the yellow sticky mess inside. It actually wasn't to bad as I had sprayed some cleaner in there when I first got the gun.
Plate popped right off, no problems with screws no problem with re-assembly. Always great fun removing the side plate from a revolver!
Just note that if you attempt to remove the plate from your revolver be sure you do not pry the plate off! Just tap the guns handle (with the plate up, and grips removed) with the plastic handle of a screw driver. The plate should start to come up. And when re-installing the plate be sure the hammer block in in correctly, you want it pushed all the way up. Also be sure to slip in the top corner of the plate first then press firmly. You should get the plate down about 90% of the way then you can slowly draw it down with the screws.
Make sure you keep track of the far right screw, the one closest to the barrel. This screw holds on the cylinder and has a little spring and pointed cap that you do not want to lose!
