I wanna say I saw the 30274 part for the 9mms on GlockParts.com for ~$8 + shipping a couple weeks ago but I'm not seeing it there now. Whole trigger assembly is only like $10 but is showing as backordered at the moment.
I just got the 30274 in my 17 Gen 4 this weekend and the combo of it and using 124gr ammo seems to have greatly improved the stovepipe and crazy ejection issues I was having. Still haven't got to try it w/ any 115gr ammo after the ejector swap yet though.
