Sure hope you guys wear safety glasses while taking guns apart. While taking guns apart and cleaning them, sometimes my hands get a little oily (slippery) and I have lost my hold on the recoil spring plug and have launched the plug almost high enough to orbit the planet....well, maybe a slight exaggeration.
Anyway, I always make sure I am not directly under a light fixture and now clean the guns in my outdoor patio so when I launch a part, it usually hits something stucco and doesn't do any damage. Also keep a few spare springs and recoil springs on hand because sometimes it takes me a few days to find those parts. With the spare parts I can put my gun immediately back in service and leisurely search for the missing parts with a surefire flashlight and a cold brewski.
May the Schwartz Be With You.
