"Rad, But You'll Need a New Spring"

USP Full 9mm

Overall Product Rating:


This thing is sweet! Very happy with it, but you should know it does NOT come with a longer spring and the one in your 15 rd mag won't put enough tension on the follower to lock the slide back. I ordered the 18 rd Jet Funnel spring and it works great. So, make sure you order that too at the same time to save on shipping (learn from my experience!)
