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.
First match report

Springs approximately 1.5" longer than OEM. I guess this is because of the 10 round mag extensions shooters commonly add. Wire gage same diameter (.054") as OEM. Used in practice and PCC match this past weekend - about 200 rounds. Performed perfectly. Original OEM springs had failed to hold bolt open after a year.
You need this!!!

I bought three basepads (TTI) and they didn't come with the Power Spring (I purchased thru another vendor). The bolt wouldn't lock back. So a buddy told me I needed these, man. I'm glad I got them. Bolt locks back, good pressure when you load the magazines, and also no feeding issues. Thanks.
