640 Pro Series

I am also considering to purchase this gun - I need a small J frame for pocket carry. After I could not order one locally, I contacted S&W. They told me that there will be another 640 Pro production run in June and the gun will be available for order again.

I still cannot make up my mind between the M&P 340 and the 640 Pro.

I am currently stuck in the dilemma of choosing the 640 Pro Series or the M&P 340. Which did you choose?

Any help from anybody on here as to which one to choose?

Weight is the question. My 640 Pro is as light as I want to go for shooting purposes. I have shot a friend's lightweight S&W J-frame and it stings.

If you expect to carry and not shoot it often, then M&P 340 may be for you. If you want to shoot it more and the extra weight isn't an issue for carrying, I'd go with the 640 Pro. I love mine.
 
I have both a 640 Pro, and a 340PD.

For belt or ankle holster carry the 640 is much preferred. It is easier to shoot, and the weight does not bother me at all on the belt or the ankle.

For pocket carry the 340 is preferred. The stainless steel 640 is just too heavy for comfortable carry in the pocket.

On the range I practice with 38s on the 640, and then fire 5 rounds in .357 to finish off.

I fire just 5 or 10 rounds of .38 out of the 340PD on the range. larger quantities leave nerve bruises that take time to recover.

I carry 4 rounds of .38 in the 340 with the last round in .357.

I rarely carry the 340 as I wear a jacket or untucked shirt to cover my S & W 686 on the belt, and my 640 on the ankle.
 
Me Too

This old thread hooked me too. I ordered one from Bud's. Mine, a 640-1, came with a very heavy trigger pull. I changed out the hammer and trigger return springs with a lighter set from Wolff's, and the pull is much better. I told myself I was ordering this one for my wife, but after taking it to the range, I don't know. She still thinks it's hers.

I've heard that several times reading the reviews but it was with the Pro Series model. I was seriously looking at them a few months back and went on site to a favorite gun dealer and every single review was bad. People where very upset having spent close to $700.00 dollars. I had the same problem with one of my 642's, no lock version, the other one I had with the lock had a reasonable pull. I was thinking maybe if you don't get the lock version they purposely make the trigger heavier. Either that or they are very inconsistent with thier manufacturing.

I like a pull no lower than 8 lbs. and preferably no higher than 14 lbs. Makes me feel better about having it so close to the gonads.:) Although my new CCW is riding in my back pocket cause it's a BIG gun. And the trigger pull is perhaps even more important because it's a reach around affair to draw it out without blowing a hole in the gluteus maximus :o.

Strictly speculation on my part, but I wonder if S&W is currently producing "no lock" guns with a heavier trigger pull to better child proof (or law suit proof) them.
 
I just bought a 640 Pro Series yesterday. Great little revolver. Mine is marked 640-1 on the frame inside the crane, has no lock, night sights, fluted barrel. I'm wondering if S&W has a bunch of previously produced 640-1 frames, and is using them to produce this series, or if these are new production? Anyway, haven't shot the gun yet but will remedy that tomorrow. Looks like it's going to be a great little gun, and probably a constant companion.
 
I wondered about that myself. I imagine that they would only have to eliminate the machining operations for the lock to make a -1 frame, but I don't know for sure. Possibly they used up some old frames to test the market for this gun, but I'd be surprised if they were still using old frames.
 
Look at the barrel on the Pro it is a custom proposition to the 640 Pro only!

I've had mine since first announced at SHOT show several years ago. Shoot Speer SB 357s in it and the Tritium sights are still bright.

Did add a Hogue Tamer grip to help with recoil but the only add on to the weapon!
 
I bought a 640-1 Pro Series in early June 2016. I've shot it a good bit and am quite pleased with it. I own quite a few J-frames and pocket carry a M&P 340 with CTC grips all the time. I may add a Shield 9 or .45 or a M&P 9 Compact at times, but I never leave the 340 at home. Never. To me the 640 PS is a bit heavy for pocket carry. I have yet to be able to find a suitable OWB holster for the 640 PS. What are you guys using for yours? Thank you in advance for your recommendations.
 
Thanks Packard, that is a nice looking holster. Wish I could wear one, but I'm over 60 with sciatica. I am no longer able to wear an ankle holster. IWBs are a no go, except for very short periods of time, for the same reason. I'm limited to OWB holsters.
 
What is the barrel length of the 640 pro? I have a no dash 649 and wondering if the pro will ride in the same simply rugged owb belt holster. Thanks for any info provided.

I'm 68 and I only reach for the ankle holster when I'm seated; for all other situations I have a medium frame .357 in a pancake which is convenient when standing but nearly useless when seated , especially when belted in the car.

So the answer is two guns.

I'm 63 and know exactly what you mean. I agree with you, two guns is the solution. I have Rusty Sherrick making me a crossdraw holster for my 340 to use when belted into the SUV. It should be delivered within the next week or two. If I like it I may have him make me one for my 640 PS. But I'd still like to have a strong side OWB holster for the 640 PS. I've been looking at the Milt Sparks PMK. I may call them tomorrow to ask if they can make one for the 640 PS.
 
I have a Simply Rugged holster for my 686 Pro and one for my snubbies. It is open at the bottom but my 640 Pro does not protrude. They are my favorite belt holsters. They hug the body, they're comfortable, hold the gun secure and they are fast to access. I've probably spent a small fortune on holsters over the years but these are my absolute favorite.
