There is a 3rd group. I know of at least 1 member of that group. Has identical micro9 pistols. One was bought as a home defense gun. That one is well used and very well functioning, the other which he bought as a desk drawer gun for the office based upon the performance of the first gun…straight lemon. He has one he swears by, and one that he swears at. I have asked repeatedly to take both guns and start swapping parts to see what part is the offending hunk of iron, but he doesn’t want the guns disassembled. It’s a shame and a waste.
