Whew...lotta heat in this discussion...but the OP's premise, loudly voiced, is that his choice of a snub-nosed revolver with a hog wallow rear sight is the be-all & end-all doesn't hold up.
Deer at ~100 yds...probably a scoped, long bbl'd revolver of proven accuracy makes more sense.
Binking cans off the berm from 50 yds, maybe a standard duty sized revolver with adj. sights so it's pointing where you and your loads are looking.
Targets at 25 & 50 yds...a good target sighted name brand revolver of proven accuracy...
Serious social encounters at bad breath distances because you'd forgotten to pay attention to your surroundings and lost your sanity when you stopped for milk in the bad side of town...MAYBE a fixed sight gun of substantial caliber. But that feather weight cannon, so comfortable on the pants belt, will be a super-snarky-handful for any 2nd shots.
All are personal choices which can and should be made; determined by the needs of the shooter and his targets. But to pick one underweight for caliber revolver with non-adj. sights as a universal panacea is ludicrous.
Glad he likes the gun...but I predict it won't get much range time with substantial, read SD loads, because of the light weight/heavy recoil, and that it'll fade from regular use.
YMMv, Rod, PS: forced to pick one revolver for all uses, I agree with 44 AMP, it'll never have a 2.5" bbl. My choice for this ridiculous scenario is a 4" bbl'd, M66 Smith: SS construction for weather, superb accuracy WITH ADJ. SIGHTS for load adjustments, enough weight to absorb recoil but not so much to deter daily carry, and a DA trigger that's the industry standard short of a custom gun. And I'll carry it OWB and dress around the gun for CC use...flame on brothers! Rod
