While at the range the other day, blowing off some ammo to test magazines, I had my trigger pin work it's way out of the hole part way and jam up the works.  Having never had this problem, I figured I would call upon the collective wisdom of ARFcom.  Should I just replace the pin and be done with it?   Are those "anti-walk" pins worth the effort? [I don't like the looks, but if they work..]
I don't see any obvious broken parts, but it happened three times in a row, all during bump-fire.

trigger pin is retained by the legs of the hammer spring. are the hammer spring legs on top of the trigger pin?

The pin didn't come all of the way out, only about 2mm, enough to come out of one side of the reciever and allow the hammerspring to misalign the hammer.  The spring, hammer and pin are in proper relation to each other.

most likely then the diameter of the wire used for the hammer spring is too large in relation to the annular groove in the trigger pin. you can grind the legs into more of a V shape/deepen the groove in the pin or RR either part.

This sounds like I ought to just replace the hammer spring and the trigger pin..  after all, the parts are cheap enough.

I've seen more hammer springs made from too large a gage of wire than shallow trigger pins grooves. always good to have spares tho.

you could put in anti walk pins

I have seen those, but aestethicly (sp) they don't appeal to me.  I was thinking more along the lines of a dab of blue loctite in either side, that ought to be enough to keep everything where it should be without gumming up the works too bad...

Never was keen to the idea of the "C" clip spinning around and scratching the hell out of the receiver anodizing finish.

As for the exsiting trigger pin,
might help to just chuck the trigger pin up in a drill, and use a jeweler's file to spin file/ deepen/widen the annular end groove. If your like the rest of use, you already spun the pins to smooth them out with 600 sand paper, and may have swallowed/ narrowed the grooves then.

I had the same problem until I realised the hammer spring was installed upside down, it will work that way but the pin will walk out.
