I switched out the lower for my printed version and double checked the operation. Would it hold up? Again, one round in the magazine, cock the gun, squeeze the trigger, and… Wouldn’t you know it, I shot my eye out. Just kidding – it functioned perfectly. Testing again with 2 rounds, then 3 rounds, then a full magazine. Everything ran just as it should, magazine after magazine. To be honest, it was acting more reliably than a number of other .22 pistols I’ve shot. I ran close to 100 rounds through the gun before getting annoyed with not actually being able to aim at anything, and decided to call the experiment an overwhelming success.
