Mike over at Mike’s Custom Weaponry has sent in photos of his latest project in the final stages of completion which happens to be a semi-auto version of the Machine Pistol from P.A Luty’s book Expedient Homemade Firearms Vol 2. The original design is of course fully automatic but with a few changes, namely an AR trigger group and a floating firing pin, a legal semi-automatic version can be made.

He writes:

“I started the project as something to do on nights I had trouble sleeping. I wanted to see if I could build this gun using only materials I had on hand. I chose to make it in .380 because I had a little over 300 rounds, but no gun chambered for .380.”

“Here’s the homemade magazine. I haven’t built a sheet metal brake yet, so it’s a little rough, but should function just fine.”

“Removing these two screws will separate the upper and lower receiver. ”

“Here you can see the modified AR trigger group. The hammer is the only part that needed to be changed. The trigger and disconnector are unchanged. I did need to make the pins longer though.”

“The feed ramp is integral to the magwell as in the original plans. I sized the magwell to fit the magazine. The plans actually called to use 20x40mm rectangular tubing and use a spring to take up the extra space. “

“The plans called for the recoil spring to be in the center of the bolt. In order to make room for the firing pin and hammer I moved it to the upper corner of the bolt.”

Removing the barrel:

“Here you can see the chamber. In the spirit of this build I chambered it using only drill bits. I haven’t tested it for accuracy yet, but it functions perfectly.”

“And finally here’s everything laid out. The grip is just a simple chunk of aluminum, nothing special there.”
