Beagle;
Your post set me to thinking. It would be very hard to intelligently disagree with your "wants". I, a few short years ago, I picked up a VERY nice Model 15 at our local gun club from the sale table. It was priced really right and was in at least "very good" to "excellent". It was an ex-LEO piece and was so marked. It showed almost no use. It is a near perfect field piece as well as VERY satisfying on the range. My son and his wife needed a "house gun" and I was happy to gift them with it. The .38 Special when properly loaded is an excellent self defense load.
I have used a variety of .38's in the field for small game use and found it NEVER lacked when loaded with a proper home cast bullet. Instant stop with no excess meat damage. I have several .38/.357's so have that area well covered. I also still have my K-38 from my PPC days. It has also been useful in the field, also.
I was always "behind the curve" looking for a K-32. Finally, I managed to get a 16-4 when they first hit the market (dern near broke my arm getting my money out). I bought the six inch and still have it. It is a DANDY! It shoots both the .32 S&W Long (when properly loaded) as well as the .32 H&R Mag (after Starline started making brass for it) at NRA Bullseye levels. I also managed to pick up a 631 (4" .32 H&R "J" frame, as you well know) when they were first offered. I, OF COURSE, still have it. The .32's have done well on small game, too!
I never felt the pull of the .22 magnum although friends have used them with excellent results. The factory ammo has always been rather expensive and I have little truck with rounds that cannot be reloaded.
I have been fortunate with the .44's and actually have successfully used them on both small game and the .44 Mag on a number of whitetail deer. They have seen a lot of range use from me, too.
I have not neglected .45's in the field, either. That has mostly been the .45 ACP/.45 Auto Rim, however. I have not used the .45 Colt in the field but do have some nice pieces in that caliber.
I fear I have gone a bit far afield, here, this really should be about Froggie's custom K-32. I am looking forward to a chance to examine and shoot it when the opportunity presents itself.
FWIW
