Yes, most manufacturers only do runs of 32 caliber guns every now and then, typically making 500-1000 at a time. Last big run was when 327 was introduced and many of the guns made for it haven't been generally available since then. Hopefully S&W will make another run next year of the 632 or do a Model 16 run. Generally Ruger has done a better job of supporting the caliber, currently you should be able to get a Single7 as well as the LCR in 327, they are available from the distributors Lipsey's and Davidsons, maybe an SP101 might still be on the shelves of your local store. But the Henry lever guns, GP100, 632's and Taurus's are all out-of-stock and have been for a while.
