The 3" SP101 '.327 Magnum' at my pusher last Friday was $429.99. As much fun as I have had with my 4" .32M SP101, I'd say it's a bargain - if you can either make your own ammo - or afford the commercial rounds. My 4", LNIB bought just over a year ago, was a challenge to clean-up due to manufacturing slop (roughness, burrs, etc). After so-doing, I regripped and resprung it - wow, what a fun revolver!
I make my ammo, my favorite being a 115gr LRNFP (.32-20 slug) in .32 H&RM cases making 830 fps - and hitting close enough vertically (The cheesy 'adjustable rear sight' on the SP101 is windage-only!) from 12-25 yd to make it a fun plinker. I suppose the existing Georgia Arms 100gr JHP (XTP) in .32 H&RM makes 1,186 fps from mine - ought to be effective, too. Oh yeah, it'' top 1300 fps with a new '.327 Magnum' offering, 85gr I believe, and whose case is .125" longer than the .32 H&RM.
