In revolvers, in my view, you get what you pay for...especially if you want reliability and something that will maintain its value long term. Personally, I'm a big guy too ( 6'5" and around 290...)...so carrying a gun, is about the right gun that fits my hands ...vs the discussion of plus or minus a pound ( an extra pound is not what is holding me down to the ground )...let alone a few ounces.
I have a few revolvers in .357 mag under a 4", some in 4" as well, etc...the difference between carrying any of them is not a big deal...all S&W - all in .357 mag. S&W gives you a lot of gun for your money in my view ...and they fit my hands well ( K frames are a little small, but I adjust by changing the grips). I would recommend any of these as viable options ( from $ 750 - $ 1,250 if you get into N frames ).
All weights are "loaded"
Model 66 2 1/2" K Frame ( 6 shots ) 2# 3oz
Model 686 2 1/2" L Frame ( 7 shots ) 2# 9oz
Model 627 2 5/8" N frame ( 8 shots ) 2# 11.2oz
Model 66 4" ( 6 shot ) 2# 6.5oz
Model 27 4" ( N frame ) 6 shot 2# 14 oz / model 28 would be cheaper but same dimensions.
and only because I have one ...a model 627, 5", 8 shots, N frame is 3# 1.2oz
My point is ...with a good belt and good IWB holster...they are all easy to carry ( I prefer Kramer leather holsters, with FBI forward tilt, between 3 and 4 O'Clock )...
I like carrying the 627's in the 8 shot... 2 5/8" is really easy to carry .../ but so is the 5" model 627 and its longer sight plane makes it a lot easier to shoot accurately / but same on any of the 4" guns as well over the 2 1/2"models ...
and the model 627 in 2 5/8" is only 8oz heavier than the K frame model 66 in a 2 1/2".
But its your money, everyone should buy and carry whatever they want.
