Exactly! The 21 is not "well-designed." It is an adaptation of the smaller 950 series, as is the .32 Tomcat. The .25 cal. 950 was extremely reliable. The .22 cal 950s were designed as tackle box guns and plinkers-although the .22 short is a much easier round to feed in a small pistol than the LR. Some of the 21s work very well. My point was that the LR presents more problems feeding in a small auto than the .25.
The Uniques were very well made guns. They made the 2nd model "Mikros" in .22 short/.25.
