300's broke my 629-1.
Trigger pivot pin. Sideplate held it kinda where it should be.
Double action no go, but still worked single action.
Buddy called Roy Jinks from work (he shot the Masters with him) and Roy said "sounds like warranty work". Had the gun back in 4 weeks, like new........cost me $5 to ship it (early 90's).
There is a reason why they had the "endurance package" in the Classics. Dunno what version also got that in the "regular".
240's max'd out is as hot as I've run since, in a couple of other 629's. No probs.
I'm just wimping out in my old age, have pretty much given up .44 handguns, wouldn't mind a 6" 686 (pre lawyer lock).
