I purchased one, shot about 1000 rounds through it, and then sold it. I thought it was a neat little curiosity.
The pistol I had was very accurate and permitted very fast follow-up shots, and had no failures of any kind that I can recall.
If ammunition for the pistol was cheaper, I might have kept it for fun. I never carried it and never saw it as a particularly appealing carry gun given the low powered civilian ammunition that was available at the time.
Apart from being really cool to have one, is there any other particular use you had in mind for the pistol?
