K-Frame Load/Sight Regulation

[Wingate's Hairbrush]

...The only fixed-sight .38/.357 S&W no-lock revolvers I’ve owned—which is a bunch—that didn’t regulate for 158 grains were the Brinks contract "NY-1 spec" model 64s. Annoyingly, they're set for much lighter loads, eg. 110 grains. Beyond that, what everyone else has said.

Were they using the old +P+ Treasury load for those? They ran 110 grain, if I recall, and were used during the NY1 time period.

That's kind of interesting. Keep in mind that I generally don't know shit from Shinola, but I always thought that the S&W Model 68 (the old CHP Revolvers) was the only factory tuned revolver for that load.

ETA: Correct Model # certainly helps with the conversation.

My 28-2 shoots nicely with a 110gr .357, but it also has adjustable sights. It is a hoot with any .38.

I bet it does. I meant the Model 68. My bad.

Yeah, I figured there was a typo in there somewhere.

No idea. My understanding is that "Brinks" is a bit generic; the contract overruns may well apply to several armored car companies.

Honestly, if I had a NY1 regulated for 110gr I'd happily use Hornady Critical Defense standard pressure or CorBon DPX and never look back.

That is a very good point. When I had the brinks gun, *every* other revolver in my safe chambered in .38/.357–and I'm talking double digits—shot POA with the thousands of rounds of Federal and Remington "FBI" cartridges that I had socked away. If it had been my only revolver, I’d have sorted it out, but it was the lone Japanese sportbike rider in a club of 1% Harley patches, if you get my drift.

Time to sauce up this thread with pics, for the high-information voters:

More. You can see the black trigger (MIM) and hammer set off from the NY-spec bead blast on this DAO "Brinks" gun. It was a serious looker. If only the damn thing wasn't off by *inches* compared to the rest of the stable.
