old boito shotgun

[Stillhunter]

Have an old 410 single shot boito shotgun,it has been refinished & re-blued and looks great,but when the hammer is in the firing position it can be pushed closed with your thumb without touching the trigger,rather easily to. I do know these are old cheap k-mart and hardware store shotguns,I would like to fix it,but don,t want to have the expense of a gunsmith in a cheap gun. Could someone help me get started on what part is worn out,so i could possibly fix it myself?

I disremember at this remove - especially since I never touched one of those Boito's - but if it has a rebounding hammer, what you're experiencing is normal.

It looks like the trigger is the sear if I'm looking at the right blow-up. You can see if the edges are rounded and square them up or Gun parts corp has the trigger in stock.
