Before inserting my thoughts on the difference of these two models I'll just ask.
What is different about the 640-1 that caused S&W to add the -1?
Thanks

I think the -1 was the version that allowed the Centennial to go to .357.
Despite the Internet experts, I find the 640 easy to pocket carry and doesn’t create such a burden.
Not sure what’s so bad about night sights
So people who've tried it and found it too heavy for them don't exist? They're just making it up?
Just because it works for you doesn't mean it works for everyone.
In total darkness, I find them terribly distracting. I didn’t notice that so much initially during lowlight training, but when I was convinced someone was breaking into our home one night, my opinion changed dramatically and I immediately moved away from them. YMMV
A couple quotes...
“I am not in the camp that recommends night sights.
Nightsights are a big marketing thing. They have their place, but that place isn't justified by the overwhelming presence in the marketplace except for the fact that they sell well. The conditions under which nightsights are actually very valuable are pretty contrived, for example:
Enough light to see/indentify the threat, but not enough light/contrast to line-up the sights and the need for precision dictates precise sight alignment. Perhaps you are in the dark and the threat is in a decently lit room, but wearing dark clothes and not within 10', for example.
I think (hope?) we are past the point where people are preaching a "need" for nightsights.“ - Rob Pincus
“Here is the thought - if it is dark, but there is enough ambient light to see my adversary, I neither need "night sights" nor a flashlight. I just shoot as I do during the day. If he is close, he is a short time frame problem. I shoot him. If I can see some sights, cool. But I am not waiting to see them. If he is far away, I probably won't be able to see where he is in dark environments so nights sights are of no benefit. The more I work with this, the more I am convinced that plain black non-illuminated sights are the best option for a CCW pistol.“ - Gabe Suarez
The 640-1 was my on duty second gun and one of my off duty sidearms. As has been mentioned earlier, with .357 rounds it is a handful, but .38 special +P loads were not an issue.
