cleaned and lubricated my 1911 today and had an odd thing happen. i do 2 "hard/violent" slide pulls during my function check and it stuck open on me multiple times. to the point where i had to smack the back of the slide to get it to go forward again. this was while empty, no mag.
i disassembled and checked the guide rod and recoil spring. all seemed well. after reassembly i have not gotten it to stick open.
any thoughts to a cause of this?
