I just got my 640 pro and am going to the range tomorrow with it.

I have noticed on most (if not all) the newer stainless revolvers, the trigger seems to be discolored. Is it a different kind of metal, or just discolored somehow? Different heat treating process for some reason maybe?

Also I am probably going to get some speed strips , any recommendations on the best ones?

The hammer and trigger on newer revolvers are MIM or Metal Injection Molded. They are not forged from stainless steel.

If you want 5 round speedstrips, Tuff Products makes some.
If you don't mind carrying a 6 round speedstrip with your J frame, then Bianchi strips are just fine.

The only stupid questions are the ones not asked...

Re speedstrips, I've found the Tuff strips to be flimsy, even though they are produced in several caliber/number combos (5,6,8 rounds). The Bianchi .38/.357 strips are sturdier. I've carried them every day for years. Good shooting.

Get a 6-round speed strip for best grip.

So glad to have finally figured this out! I have taken heaven only knows how many chemicals to my trigger and hammer, plus a wire brush trying to get it to shine. But seems like it was all in vain anywho lol. Thanks!

Are the MIM trigger and hammer case-hardened?? That would explain them not taking a shine.

The nature of the material explains its appearance. MIM parts are of uniform hardness throughout, making them superior to casehardened parts in many applications -- the hardening will never be worn through, or removed by a ham-handed attempt at a trigger job.

If you want shiny, use a drimel tool and Mother's. I did it to my 696-2 and couldn't believe the results. The picture doesn't show the trigger but you can tell by looking at the hammer. Good way to kill a rainy day!

any reason you don't want to take advantage of the moon clip feature on your 640 pro instead of using speed strips?

I really consider the moon clips to bulky to carry in a pocket. I don't want any pouches on my belt. I bought this as strictly a deep concealed carry piece.

Welcome to the forum!

I also use and recommend the Bianchi speed strips.

I don't carry the moon clips either.

But then, what do I know?

I was about to ask this...speed strips SUCK for "speed" They are, however, the only way to carry around extra ammo at a low profile. I highly suggest getting a strip larger than your round capacity and doing 2 rounds, skipping one, 2 rounds, skipping one, etc... Otherwise it is way too hard to reload and youll have no grip on the strip. Also, despite the thousands of rounds I fire through my gun, I just didnt like how the strip clips scuffed up the outside of my cyllinder as the rounds where pulled off (from the rounds yet to be loaded in)
