The 2024 Buyer's Guide from Salvimar has this listing of new spear tails and sliders for their pneumatic spearguns.
The 45 degree angle on the face of the spear stop diameter and the matching rear face on the stop ring is to create a better passage through the vacuum cuff with the high speed exit of the shaft. A soft face in polyurethane has been used on spear tail stops by companies such as Taimen, it will be interesting to see if these 45 degree angled faces hammer up with repeated blows. Some of my shafts have developed angled faces due to being hammered, they once were 90 degree stops. The transformation was caused by stop rings jamming on the shafts and having to be bashed free, not always possible in the water and spelt the end of shooting with that gun and another brought into action, usually a shorter spare gun. Always carry two guns on a dive.
These new inox sliders may only take mono, but I hope they will take woven line as mono can be cut on some bottom situations and with a knick in the skin of the mono the strength plummets. Like a cut in a tomato.
