Hey there guys, I'm new here. I just recently inherited a 645 from my uncle in good condition. Fits my hand really well, shot it once so far and loved it. Making some minor tweaks/personalizations (LPA adjustable sights, wood grips, thinking about getting it hard chromed).

I'm wondering if any of you guys with experience have an opinion one way or other about the 645? I can't really find anything negative in my searches and most people say it's very reliable.

Are there particular parts I should be on the lookout to buy as replacements if something breaks? By my understanding Smith no longer supports this model and new parts are no longer being made.

In my opinion, it is a fantastic weapon. I bought NIB when I read an article in Guns&Ammo when it was first introduced.

The only issue that I ever had with mine was the screw on the off-side of the safety came loose. Back then, S&W had a retrofit for me.

Other than, it is one of the slickest weapons that I own. The reset from single-action to double-action in my trigger is less than 1/16" and gives you a very controllable double tap.

They said in the article that it would actually feed an empty case out of its magazine so I had to try it....and it did. Lets see one of those "plastic" guns do that

Just curious why would you hard chrome a stainless steel pistol?
 
T-bird the 645 is at the shop right now getting sights put on and some trigger/spring work done but I'll try to get some pictures put up eventually.

625, the stainless steel is maybe 40c. Hard chrome is about 70c. Reduces wear all around, looks good and doesn't pick up handling marks like polished SS.
 
I like mine

Just the way it came except for some wood grips from Hogue, which happened to be on sale! It is also heavy enough to make a nice blunt object if you run out of ammo!

Historical note. Hunter S. Thompson used his to exit this plane of existence. Weird dude. IMNSHO, he deserves condemnation because his very young grandson was in the next room.
 
mwtdvm, tmi...

I guess when I get it back I'll have to see if I can polish out the handling marks (probably). I'm just thinking besides looking good hard chrome might increase the service life. This is Metalife SS Chromium M btw, not bumper chrome or pimp finish.

I think you'll find that most folks around here know the difference between "bumper chrome" and industrial hard chrome. Scratches on the brushed stainless steel flats can be removed by using the correct Scotchbrite abrasive pads. Scratches in the matte finish areas are dealt with by re-bead blasting-not an expensive proposition.

As far as extending the service life, I've never heard of anybody wearing out a 645 or a 4506 or any other of the large frame Smith autos-have you?

I personally like the looks of hard chrome but it's highly unusual for somebody to apply the finish to SS, hence the questions. Carbon steel is a different story but everybody likes what they like.

Hey Bruce, thanks for the info. I've seen videos with the gray scotchbrite so maybe Ill give that a go. Didnt realize the hard chrome was such a touchy issue, didn't mean to offend.
 
It's not offensive but rather a restatement of what is obvious for the most part or, as Robin Williams says: "immediately after the word "redundant" in the dictionary, it says "see redundant"".

:D:)

Incidentally, while I really like Hard Chrome on carbon steel, I've never especially cared for the appearance of either Armoloy or Metalife. I'm more of a brushed or matte kind of guy instead of that satin finish.

Best out of the box 45 ever made. You can still get parts from Smith as well as get it repaired if needed. There are also lots of places online to buy parts from. I've owned one for 26 years and have had no issues, no stove pipes, and no failures to eject. I'd leave it as is.
 
I carried mine as a duty gun. Wish I would have left the sights alone. I put Millets on mine.

I've had two and IMHO, the 645 is about as tough a pistol as ever made.
In fact, my one gripe with them is that they tended to be a bit big and heavy for my tastes. My advice, if it has sentimental value leave it alone and shoot it. If you're just looking for a custom 45, then leave it alone and invest in a 1911. While the 645 is a great gun in it's own right, it's not the 1911 preferred by those 45 enthusiasts who are willing to spend what you'll have into it. Enjoy the gun for what it is and save your for ammo or the bug for your next gun..

p.s. One of the great joys of stainless working guns is that you can polish just about anything out with some combination of flitz, grey scotchbright and mother mag polish.

I have one and other than some trigger work its bone stock. It feeds anything I give it and shoots like butter. One of my very best shooting (and best looking) guns I own.
 
Once you have one a while, you'll understand why they aren't that commonly seen for sale. Those that have them tend to keep them for a long, long time.

Z-Max, in atleast this case, your uncle had good taste.
 
Great pistol, Don Johnson carried one in Miami Vice. Leave it stock! I'd hate to carry one, but love the way they shoot. (only one season I think, he also carried a Bren Ten and a Detonics)
 
I agree with the others, they're very nice. Once I saw one I knew I wanted one. Here's mine.

Aaaaaaa the 645, nice gun. I had the privalige of working on the development of the gun while in R&D. It was very reliable and a good shooter. As far as parts you'll need? Unless you plan to shoot it 10's of thousands of rounds you won't need any. It was that reliable. As far as getting it chrome plated? Not a good idea. It will cause you more problems than its worth. Anyway, enjoy it.
