Rimfire revolvers, in most instances, have stronger hammer springs than their center fire counterparts. As a result, the pull is stiffer. If you try to tune it up & trigger-weight down, you risk FTF from light hammer strikes. Between the two you've mentioned, I'd naturally lean toward the S&W. I sometimes carry an alloy-frame High Standard 9 shot .22 mag snubbie. Very nice & light, plenty of capacity, and handy.
