HW 45 Tinbum drop in kit

[Reevo17]

On my old 45 I fitted the tbt kit and an OZzy parachute seal! That’s next level - felt like a different pistol and no slam whatsoever

Interesting thread, I'm thinking about putting in a new spring and getting an Aussie seal for my single power 1988 .22 HW45, does the seal make a big difference?

Thought about the TBT kit too but unsure if its worth it for the .22, I also have a .177 twin power from 2005 so thought the TBT may be better in this calibre?
