S&W steel frame revolvers are the best there is, in my opinion. However, those alloy frame revolvers, that weigh nothing, are very uncomfortable to shoot.
I had a Bodyguard in .44 Special with an alloy frame and it was extremely uncomfortable to shoot. .44 Special, in a steel frame gun, is an accurate and wonderful cartridge.
With the proper grip, (one of the six fundamentals of shooting), there should be no problem with "regripping" the R9.
