640-3 .357 is this acceptable

[SW CQB 45]

A buddy asked me to detail clean his 640-3.

I think he bought it a few years ago off of Gunbroker (brand new)

I came across a forcing cone that looked like it was cut with a dremel coarse sanding drum. It appears the rough cutter also pushed an edge of the lands into all the grooves of the barrel. You can see it at the arrow and looking down the muzzle, you can see the areas of the pushed lands.

Is this a known issue with SW.

Will they fix it.

I also found the pushrod from the trigger to the rebound slide to have a big gouge from contact with a corner edge inside the trigger.

any info or home fixes will be appreciated.

S&W quality control, where the purchaser finds all the issues with the product. I do not think this is acceptable, perhaps S&W will fix the issues.

push rod looks bent and at least looks used. cant believe that came from a new gun...who said it was new when bought? "I think" doesn't get it

Both need to be fixed. The forcing cone recut, the trigger lever replaced. Smith may fix them or they may say in spec., don't know. I would try to find a local gunsmith if possible.

The trigger lever was most likely dinged up in production. It's not worth the trouble to send that back to be replaced.

Because of the really short barrel tube on most J frames, it's tough to get a good forcing cone. There just isn't much room for alignment bushings. I've occasionally wondered if they just have a powered reamer and the bare barrel is free hand reamed before it's installed in the frame.

A lot of machined parts production is/was based on a piece work pay system. You're expected to produce XX parts per hour. You do more, you get paid more. Once upon a time at a brand with a 4 letter name, you could leave and still get 8 hours pay once you made your 8 hour production quota. Not sure how that works in these days of CNC machining centers.

I am guessing as to if he bought it new or not. I recall gunbroker and is several years old. I will speak to him today.

when going back together with the internals, I looked at the trigger push rod bend when installed. with the bend pointing upwards looked right compared to down.

The pushrod is not pinned to the trigger. It has a flatten round portion that rides inside the trigger. When I first took it apart, I said to myself where did that part come from. After inspection, one can see the relation of the pushrod to the inside of the trigger.

I will call SW this week.

thanks for the info.

I wondered this

it's not a target piece and he has not complained of any issues. He qualifies with it and the longest distance is 25 yards.

I will still check with SW.

thanks

It's not the workers. It's the boardroom telling the managers to crack the whip to get product in a box and out the door. The workers have to do whatever they are told. Do good quality or go faster comes from the top down.

Well, I got this all wrong.

He bought the 640-3 brand new from a gun store. He has shot it a few times but has had zero issues.

The gun he qualifies with is a 642.

I will be calling SW this week for the ruff forcing cone and trigger pushrod.
