anyone know where I can find the little bullet shaped threaded guides to install the pins in my colt small pin lower not sure of the brand of pins they look like K&S TIA


 

KNS has them Here

KNS pins are antirotation pins.  You need to make sure you lube the trigger and hammer pin bores after you clean, or you'll wind up wearing the parts.

Antiwalk pins shouldn't be needed; the hammer spring retains the trigger pin, and the internal "J" spring inside the hammer retains the hammer pin.  If you have pins walking, you need to make sure you have everything installed correctly.  Walking trigger pins are a nice indication that the hammer spring is in upside down...the tail of the hammer spring should be horizontal - and on top of the groove in the trigger pin - when properly installed.

That's not always true. With today's sub-standard parts on the market (including some two stage trigger groups) installed correctly the pins can still walk.

Buy quality parts.  I've never seen an in-spec hammer spring fail to secure an in-spec trigger pin.  Because that's how the parts were designed to work.  If it's installed correctly and it still walks, the pin is out of spec, period.
