Two magazines, a factory box and a pistol that police departments have used: that is the short list for this M&P45. It is a used Smith & Wesson in .45 ACP.

The M&P45 is a full-size polymer pistol with interchangeable grip panels, which let you fit the grip to your hand. The striker-fired trigger has a consistent pull, and the pistol is easy to maintain. Run the slide by hand when it arrives and make sure it moves cleanly from end to end.

If you like the idea of a big-bore pistol for home defense, the .45 ACP is an old standby. It is heavy and slow, and many shooters find it easy to control. Ammunition costs more than 9mm, so budget for practice.

The set includes the original box, which is a plus, though it does not add to the shooting. What you want to know is how the pistol runs. When it arrives, check the controls and fire a few magazines to see how it feeds. It is sold used and as described. It ships to your FFL dealer, and the background check is completed there.
