    Almost fantastic. Incomplete Upgrade

    Posted by Michael on Jul 8th 2026

    First of all, the gun is awesome. The team at WBT did an awesome job, the customer service was great. The fit and finish of the updates is perfect. The reason I only gave it 4 stars, and honestly, considered giving it 3 stars is because the gun, as you receive it, does not function. The reason it does not function is because upgrades to the magazines are not part of the package. The standard M18 magazine baseplates do not fit inside the flared Maxwell. So, rounds will not chamber, and there the slide lock does not function. The minute you use a legion mag, or another P320 magazine with modified baseplate, the gun functions perfectly and is as awesome as you want it to be.
