The Smith & Wesson M&P 22 Magnum offers a high-capacity rimfire experience, aiming to improve upon the Kel-Tec PMR30's reliability with a robust build and a 30-round magazine. Its gas-operated Tempo barrel system handles most ammo well but shows sensitivity to bullet profile and heat buildup, requiring cooldown periods. While accurate and low-recoiling for plinking and training, its suitability for self-defense is debated against 9mm alternatives.

Quick Summary

The Smith & Wesson M&P 22 Magnum boasts a 30+1 round capacity and uses a gas-operated Tempo barrel system for cycling. While accurate and low-recoiling, it exhibits sensitivity to bullet profiles and can overheat during rapid fire, requiring cooldown periods.

What are the main drawbacks of the M&P 22 Magnum?

Drawbacks include tedious magazine loading, a narrow thumb safety, and the lack of a threaded barrel for suppressor use. Additionally, the gas-operated system can overheat during rapid fire, requiring cooldown periods.
