Thank you for the quick come back ,
The model of shotgun is SKB Model 500 Over under in 20 Ga , The part I thought it was called slide , but i guess not , It is what you push to the side to break open bbl from action ,,
It has come loose and want to repair , I hope i have stated this
better ??
Thank You
John
PS , I tried to get it fixed by gunsmith in area but was told would take 2 weeks , I train pointing dogs and cant wait that long ,,
