Never owned one myself, but I have shot a couple - the S&W M52 is a very nice target gun - accurate with a good trigger. A lot of the "old time" Bullseye shooters loved them. Steel frame, if I recall.
When they were more common, there was a little interest in making them more "practical" . . . loading HBWCs backwards with a heavier than normal powder charge, or even using other types of bullets with shortened (and possibly reamed?) .38 Special brass, so the cartridge OAL was the same as a flush seated wadcutter. This was supposedly for shooters who only owned one gun and were trying to press it into service elsewhere besides bullseye matches.
Most serious target shooters decried these efforts as abuse of a finely tuned match pistol, and in fact this sort of thing never caught on.
