There's only one thing I don't like about the impact.. The clip on it is a little too short. With the rounds I just put the needle in upside down so the needle is on top of the needle bar and its not a problem.. But it's a little too short when I use mags.. It pulls down on the needle bar to much. I bend the bar or use rubber bands or sometimes those glider things bit I really wish they made that clip to stick out just a little bit more.
