fergusonTO35.... the S&W Centennial series represent the very best pocket revolvers ever made. The Ruger plastic & steel 5-shots seem to have proven extremely hardy. My problem with the little Ruger is that these are an aesthetic abomination and, worse, don't shoot to point of aim (PoA).
I don't remember a J-frame Smith that didn't shoot to PoA, or damn close. The .38 Special in a J-frame with a descent bullet is a hell of a lot better than bare hands, or a dinky .380 or smaller. My preference over the years has been avoidance of exotic materials, sleeved barrels, etc. The S&W aluminum frame is the best for carry, especially with Uncle Mike's Boot Grip. The Uncle Mike's Bird Head grip works better on a .357 variant J-frame, such as the super sweet M-640.
Issuing from a two inch barrel, the .357 mag rather fills your ears inside a car or hallway.
Note: S&W describes its aluminum frame pistols as "scandium." Scandium is an alloy used in very low percentage in firearms grade aluminum by better makers. It is not the parent material; aluminum is.
Reckon I'm an instigator in a fair number of women and men carrying a J-frame Smith, most of 'em lightweight Centennials.
