I am a big fan of "2 inch" Smith & Wesson revolvers in 38 Special. I still have 4. My J-frames are a 36 and my EDC is a 47 no dash. I also have a 12-2 and a 15-2 (the adjustable sights are worth the additional bulk). I bought all mine used and well over 15 years ago, so price paid are a moot point! With Speer Gold Dot short barrel 135gr +P, They have ample power for typical snub nose range!
I use an 8 round speed strip and feel that 13 rounds is ample for me to get away. If I intended to "Stay and Fight" I wouldn't be carrying a handgun!
The truth about steel verses alloy weight is there isn't a big enough difference to worry about. My steel guns disappeared after about 10 days of carrying! You just don't notice them in either a IWB or pocket carry!
What are you trying to accomplish? If reliability and simplicity is your quest, a J or K or Colt or Taurus or Kimber will work fine. If you think being "Trendy" will suffice, think again! 2" pocket 38's started becoming popular just before WWII and haven't let up! That's over 75 years of proven lifesaving capacities. It is safe to say, if they quit making 2" 38's tomorrow, it will be over 100 years from now before their popularity and usefulness wains!
My grandfather and his ilk carried top breaks 5 shot revolvers in 38 S&W/38 Colt New Police and were perfectly well protected! The good ammo just went away!
