I just found out about these weights, having used an SJC frame weight for a while with no issues. Is their any benefit to the Toni frame weight over sjc? It looks smaller to me but I'm not certain which weighs more.
Kinda strange that their description says it comes with a "custom" mag spring designed for open division. Then they also sell a 170mm grams spring which may get +1. Very curious what the capacity ends up being here.
Hopefully the 170's are as good as the 140's I have from TF. Their 140 with stock spring and follower get me 21 reloadable. 23 reloadable with the grams spring/follower. Edit: 9mm, obviously.
