Great to have options.
This barrel fit my 40 caliber S&W M&P Shield perfectly. There was no play as it fit exactly like the original 40 caliber barrel. I had great results at the range. The only thing I don’t like is that once installed, there are no visible markings to indicate there is a 9mm barrel installed as these markings are covered. This is a great option giving me two guns in essence. The 9mm is easier to control, the 40 caliber has more fire power. I can choose which one I want to use with a quick barrel exchange and change to the proper magazines. I’m very happy.

Works great!
I replaced my M&P Shield 40 barrel with this 9 mm conversion from Lone Wolf. Barrel dropped in with no problem. I did add a little oil to the top of the barrel, which is recommended in S&W regular cleaning instructions. I used the same recoil spring assembly that came with the 40 M&P Shield. It fit snug and performed well. I also purchased 2 Smith & Wesson Shield 9 mm mags. They fit as designed. I ran 100 rounds through it with no problems at all. I am very pleased with is conversion barrel from Lone Wolf.

Do you need 9mm magazines with this product or will the .40 ones work? Thank you.
Answer:
You need a 9mm magazine.
I don't see any reviews so I'm a little nervous about ordering this 40-9mm conversion barrel. I don't know anyone who has it. Do you have any info from people who have tried it. I would love one because 9mm ammo is much cheaper to shoot at range.

The Lone Wolf Distributers Alpha Wolf 40-9 Conversion Barrel is an excellent upgrade and have not heard any negative feedback from our customers.
