I had planned on taking some measurements and reporting them, but by the time I get to that, we'll probably on on to other things.
As much as I love Ruger's version of the Charter, they're still a bit heavy for me for everyday use, so weight plays a pretty significant role in my decisions. I LIKE Rugers more, but Smiths and copies weigh less. Charters weigh even less, until we get into the weight-war which heated up with so many states finally recognizing and respecting 2A rights. This is a subjective thing, of course, and a few ounces won't mean as much to some as it does to me.
----TOO LIGHT FOR 357-----------------------------------
Ruger, 3" LCRX, 38 Special: UNDER 16 ounces
Taurus, 3" M85, 38 Special: 16.4 ounces
---JUST RIGHT FOR 357---------------------------------
Charter, 4" Target Bulldog, 44 Special: 22.2 ounces
Charter, 3" Mag Pug, 357 Mag: 22 ounces
Smith, 3" M60, 357 Mag: 23.2 ounces*
Taurus, 3" 605, 357 Mag: 23.7 ounces
Ruger, 3" SP101, 357 Mag: 27 ounces
Rossi, 3" RP63, 357 Mag (SIX-shot): 27 ounces
Colt, 3" King Cobra, 357 Mag (SIX-shot): 28 ounces*
---TOO HEAVY FOR 357 (FOR ME)----------------------
Rossi, 3" M720, 44 Special: 30.8 ounces
Ruger, 4" Service Six (SIX-shot): 33.6 ounces
Ruger, 5.5" Flat Top 44 Special: 37 ounces (for general reference)

These are the only 3" guns I ever thought to actually weigh, but I've liked them all. The Taurus 605 was a SWEET little 5-shot, 3" 357, but the trigger pulls were horrendous. The 38s, well, the Taurus I did NOT like and the Ruger is my wife's. The LCRX is every bit as BIG as many guns weighing much more. It's nice, but not for me.
Everything between the ----- lines is within the parameters I have settled in with over many decades for an all-'round, general-use carry-gun. I LOVE the 44 Special, but reserve that for the single-action and fun/hunting. Large primers are RARE these days and I conserve them by only shooting the 44 Special for fun.
The 357 Mag, as much as I've hated it for so many years, is so versatile and useful in a carbine that I've gravitated to it for my current carry-revolver as well. It finally dawned on me that I don't HAVE to load it like it was originally loaded, and with heavier bullets, I can scale back the velocity a lot and still have an effective round for most purposes.
