Hello Frog!

I can't address whether Behlert produced his converted 41 in quantity. My question is, why are you so focused on the 32 S&W Long? I do realize that it is a great target cartridge, but it's forte has been revolvers. I think that it was the Walther GSP (or OSP) that were the more common 32 S&W Long semi-auto target pistols, followed by the Hammerli.

If you are looking for a light recoiling, accurate handgun for the centerfire stage of NRA 2700 matches, the three most common solutions have been:
a) 38 Special revolver shooting wadcutters (K38, Colt OMM, or Colt Python)
b) Model 52 or 1911 National Match shooting 38 Special wadcutters, or 38 AMU
c) 1911 shooting light 45 SWC (about 700 fps, using a 12-14# recoil spring

Figure that a 38 Special semi-auto is going to be as expensive, or more so, as a K32 or a 32 semi-auto. A bullseye 1911 will run you in the neighborhood of a grand. Depending on how patient you are, a K38 could be had for between $600-800, possibly less.

I hope that this helps.
