Model 645

You sure that plastic main spring housing/back strap is not one of those hard to find S&W Model 59/x59 arched housings?

Nope, it's too short. Just compared it to what I have
handy, and it's an exact "length match" to a 4513TSW
backstrap.

And confirmed it's plastic...took a single edge
razor blade and shaved a smidget from it.

Weren't the factory inserts for the 4/669 pistols plastic?
 
I carried this one for a few years in the late 80s. Never could get used to the looong DA trigger pull. Still a great gun though. I have cycled a full magazine of fired casings through it just to test the rumor. It did it without any trouble.




They will cycle empty cases. I cycled a magazine full on this gun with no problem.
 
KFW,
I saw that, it was at Sportsman’s Rod and Gun?
I live in Etown btw.

Yep, you got it right. Howdy neighbor, crazy how it's a small world. I always go for the used gun cabinets first and see if there is anything interesting.
 
I bought this one brand new in the box shortly after it was shipped (December, 1986) in January, 1987. It has been unfailingly reliable and will even feed empty cases manually from the magazine. It's a solid and heavy gun; shooting it is quite comfortable and the accuracy is minute-of-bad-guy at 50 yards in rapid fire.

There is a reason that the second and third generation S&W 45ACP firearms are hard to find. They are rugged, reliable, accurate and well designed. I would have liked a few more in my collection, but in the end, I am lucky to have a 4506. I hope that you safely enjoy your 645 for many years and pass it on in good shape.
 
Took my 645 to the range yesterday after not shooting it for a few years.
Man, I forgot how much fun that pistol is to shoot! Built like a tank and even my eyes were able to produce some pretty tight groupings. Friend that was with me had a Glock and both of us were way more accurate with the 645.
Now time to load some moon clips and take the 625 out to the range.

So i have read the letter from Roy Jinks . He said the 645 started out TAK0001 and went to TAK7727. Then went to TAL? Would it be safe to think that they made 7727 units in each prefix?

I'm thinking there's a typo in there somewhere ...

My 645's prefix is 'TBR,' so obviously Smith made more units of this pistol after the 'TAL' prefix.
 
Is It Real or Memorex?

Okay, Ladies and Gents, here's the final say, okay (I hope):

From our esteemed reference, a product originating from the minds, fingers and, um, whatever else of those who find time to spend here when the lawn needs scraping:

Standard Catalog of Smith & Wesson, 4th Edition, by Jim Supica, Richard Nahas and scores of S&W owners everywhere:

"Model 645: 2nd Generation .45
"Early guns have an alloy backstrap, later guns have a plastic backstrap.
" (SIC) pg. 358

"Later" is inadequately described within the pg. 348 reference, though referenced herein this thread are "12 prefixes" for the Model 645.

My still-boxed, unfired 645 has a "TAY" prefix, later than many yet earlier than still others. It has an "alloy" backstrap, as referenced, again, on pg. 348 in SCSW4. Thus, no real clue as to when or what "later" 645s are being referenced with regard to plastic.

So, Louie, you just keep on spreading that fact but, perhaps, with an added caveat about "later" so that, well, some other folks don't go into conniptions.

Later. (Which, BTW, is my standard SO.)
 
My 645 has an aluminum backstrap. It also has a hex screw instead of a phillips screw. My understanding is that earlier production gun have the help screw.

Campbell with "Supergun II". The prototype that lead to the 645.
