Just because you want to save money on ammunition does not mean you have to look like you are saving money. The Walther PPQ M2 22 LR was designed as a tactical pistol first and an affordable pistol second. This gives you the performance of a self-defense pistol and the ammo cost of a 22.
When you do want to get to the range and have some fun, this compact PPQ is chambered to hold 10 rounds of 22 LR, which should allow for nice breaks between magazine changes. The polymer frame is light-weight and features the same ergonomic grips found on the larger caliber models, which ensures a comfortable feel and makes for great training. The quick defense trigger allows for quicker follow up shots, which will allow you to perfect your double tap method. Thanks to the 3 dot polymer sights, you should be able to stay on target well enough to improve your grouping. Finally, this model features an ambidextrous slide stop and magazine release.
For those who want a compact target pistol, this PPQ offers a great way to save money while still shooting a great gun.
