Great product !!! im runing these on my TF mag EXT ... lock the bolt back every time
I use these with Taylor Freelance +10 magazine extensions. I have them on two mags and both feed flawlessly. Both mags lock the bolt back when empty and after the last round. I have about 250 rounds and one range trip on them so far. I am very pleased with these springs as the factory springs are shorter and mine wouldn't hold the bolt open.
