POTD: DIY Sheet Metal Self Loading Pistol
Published: February 25th, 2016
Last year TFB published design documentation for a DIY sheet metal semi-automatic pistol. I am very pleased someone took up the challenge to build the pistol.
The guy who is building it wrote …
I’m still experimenting with spring rates on the homemade springs and some other minor details. I hope to have some success at a multi fire attempt shortly.
He has also published videos of it being shot …

I founded TFB in 2007 and over 10 years worked tirelessly, with the help of my team, to build it up into the largest gun blog online. I retired as Editor in Chief in 2017. During my decade at TFB I was fortunate to work with the most amazing talented writers and genuinely good people!

The only question I have is what do you do to eject the spent cartridge. I believe that is why the gun was a one-peter. You need an ejector to direct the cartridge out of the way of the slide on its return. I would suggest that the magazine be modified to cause the cartridge to eject to the right side. your workmanship is outstanding and I commend you for the work you have done. My thought are to raise one side of the magazine as is done on a few early semi-automatic pistols and cut an additional groove in the slide for the ejector to ride in.
Clint Westwood, if I might suggest that you make your test jig act more like the Ransom Rest, which is made to perform more like the human hand and wrist during recoil. Your pistol will perform quite differently than when placed in a clamp (even if the clamp jaws are somewhat padded).
