The Smith & Wesson M&P45 is a full-size semi-automatic pistol chambered in .45 ACP, intended for personal protection and shooting sports. The polymer frame keeps weight at 28.2 ounces despite the larger caliber, with a 4-inch barrel and 7.6-inch total length. The double-action mechanism and 10-round capacity round out the core specs.

Detailed Features
The barrel carries a Black Melonite finish for corrosion resistance, and the slide gets the same Armornite treatment to handle wear. Steel ramp dovetail front sights pair with low-profile carry rear sights, both featuring white dots for quick acquisition. The thumb safety can be engaged or released quickly, and the textured polymer frame provides a secure grip without aggressive serrations that can wear on skin during extended carry.
The full-size polymer frame reduces felt recoil compared to a metal-frame .45 while keeping the package lighter. This matters during longer range sessions or if the pistol is being evaluated for duty use.
Target Audience
Suited for shooters who want .45 ACP in a platform that manages recoil reasonably well and accepts a thumb safety. Works for both experienced owners looking for a reliable sidearm and newer shooters who prefer a manual safety as part of their carry setup.
Usage Scenarios
For personal defense, the .45 ACP caliber delivers recognized terminal performance. Home defense use benefits from the full-size grip, which gives more control during a stressful situation. The Melonite/Armornite finishes make it serviceable for duty or range use in varying weather.
