I recently sold my 4" SP101 and SSM - both in .32 H&RM - even got rid of my dies, reloading supplies, and loaded ammo. You can load .38's for the same moola - and find the reloading components more easily, not to mention the revolvers. I bought a new 627 Pro - and a LNIB 64 - I am happier. Of course, you have to 'get it out of your system'...
Re Ruger's 3" SP101 .327M production: my theory is they used up the glut of leftover 3" .32 H&RMs, which only needed a deeper chamber reaming and restamping the caliber to become a new '.327 Magnum'. It is unlikely the SA SSMs, BHG and short BH grip alike, will be restruck. That short gripframe won't fit the locking hammer spring/strut. They closed them out ~2+ yr back - for <$300 - that's how I got my BHG SSM!
I kept my .32 S&WL ammo and brass - I'll get more reloading stuff - if I ever find a decent old S&W .32 S&WL. Maybe I didn't get it all out of me yet! Seriously, it was fun - but plinkers from that 4" 64 and 627 Pro are also fun. YMMV.
