JLM,
Bar-sto drop ins might not just drop in. I have had to fit 2 drop ins into Glocks.
Accuracy wise, the USP factory barrel is plenty accurate. I dont think much will be gained in that area with a bar-sto. If your concerned about leading in the polygon barrel thats a different matter. I shoot only ball or copper plated in all my semi's, so it's not an issue with me.
