Gun safety device and indicator

Claim 1

A universal loading indicator for an unloaded gun having a trigger guard opening with an inner circumference between a depressed trigger and a trigger guard, said loading indicator comprising: a cap formed from a flexible, resilient material, said cap comprising: a closed end wall having a generally oval shape with a first circumference in a relaxed state of at least as large as said inner circumference of said trigger guard opening and having a first degree of flexibility to permit deformation of said closed end wall when pressure is applied generally at its center so that an effective circumference of said closed end wall is decreased to allow it to pass through said trigger guard opening and to allow said closed end wall to resile when said pressure is removed; a sidewall adjoining and perpendicular to said closed end wall having a second degree of flexibility greater than said first degree of flexibility to permit said sidewall to be compressed and conform to said inner circumference; and a flange on an end of said sidewall opposite said closed end wall, said flange having a second circumference greater than said inner circumference; wherein said cap is inserted by applying said pressure to said closed end wall pushing through said trigger guard opening until forward progress of said cap is halted by said flange contacting said trigger guard so that said cap is locked within said trigger guard opening by said flange and said closed end wall which resiles to said first circumference after passing through said trigger guard opening, and said cap is removed by applying said pressure to said closed end wall to reduce said effective circumference, pushing said closed end wall back through said trigger guard opening.
