What are the advantages of using a 9mm conversion barrel in a .40 caliber Glock?

Using a 9mm conversion barrel offers several benefits: 9mm ammunition is typically more affordable and readily available than .40 S&W. Additionally, 9mm produces less recoil, making the firearm more comfortable to shoot, especially for new shooters or during extended practice sessions.
