I've wondered what the 32 capacity would be on the standard guns. I know Ruger makes (or made) a GP-100 (so L frame-ish) with a 7 round capacity. I wonder if chambering them in 32 H&R instead of 327 would allow an additional round in some of the guns that were right on the edge where going that thin between the edge of the cylinder or between them would be too much for a high pressure round like 327 fed mag.
The most interesting 32 caliber revolver I've ever seen was a custom Smith N frame that was re-barreled and had a custom cylinder installed for ICORE open class. It could fit 10 rounds of 32 and was cut for moonclips. If I had the equipment and know-how to do a project like that, I'd be tempted.
