We are pleased to offer these brand new all metal 45 round drum magazines for the popular Walther P22 pistols and G22 rifles. Made on state of the art CNC machines in the USA, you will get a lifetime of service from these. These are key wound similar to the Thompson machinegun drums and come with complete instructions. These have been extensively tested with both the 5" and 3.4" barrels. The 5" barrel functions perfectly with or without a suppressor. The 3.4" barrel funtions flawlessly with a suppressor, but without the back pressure provided by the suppressor, functioning can be problematic. We will offer a muzzle booster in the near future that will solve this problem with the 3.4" barrel. Buyer is responsible for complying with all state and local laws concerning high capacity magazines. $10 priority shipping. Insurance is optional. Multiples are available. Orders shipping to Indiana are taxable.
