Frequently Asked Questions

What are the key steps for reassembling a Smith & Wesson M&P pistol?

Reassembly involves placing the barrel in the slide, installing the recoil spring assembly with its small end forward and rear flange in the barrel's cutout, then attaching the slide to the frame by walking it rearward with the slide stop. The disassembly lever is rotated to the three o'clock position to lower the slide.

How do you test the slide stop functionality after reassembling an S&W M&P?

After reassembly, cycle the slide several times. Then, insert an empty magazine and cycle the slide again; the slide stop should hold the slide open. Drop the magazine to confirm.

What safety checks are recommended after reassembling a firearm?

After reassembly, it's crucial to ensure the firearm is unloaded. Then, close the slide and dry fire in a safe direction to verify the firing pin falls. Rack the slide to confirm the trigger resets properly with each cycle.

What is the purpose of the disassembly lever in S&W M&P reassembly?

The disassembly lever, when rotated counterclockwise to the three o'clock position during reassembly, allows the slide to be fully seated and locked onto the frame after the barrel and recoil spring assembly are in place.
