S&W 645 trigger
« on: August 26, 2008, 04:22:46 PM »
  Can any thing be done to reduce the LOONNGG free travel of the trigger on this gun? I have about a yard of "take up" then a 4 pound sear to over come. It may not really be that heavy (no trigger pull gauge) but it's definately NOT crisp!

I am not all that familiar with the inner workings of the 645 but hope they are similar enough to the 1911 to give some advice...

How do the 645s come apart?  How different are they than the 1911 design or are they just a slight modification?  Do they have the same trigger set-up and if so do you think the pistol would benefit from a after-market trigger like the Chip McCormicks or Wilsons or someone else's??? 

If the set-up is the same, or similar to the 1911 you can also 're-tension' the center prong on the mainspring to increase the trigger tension and reduce the travel?

But, on the other hand, possibly one of our more knowledgeable members could kick in with more pertinent advice.  Mikey.

I wasn't familiar with the S&W 645 so I took a quick look at a few on Gunbroker.com    They are nothing like a 1911.  The are closer to a Model 39, or a Model 952 with a trigger that pivots on a pin rather than a sliding trigger like a 1911.   I assume that the gun is DA/SA and that the long take up is due to that feature, but I'm not familar with the gun so I'll stop now.

  RB, you are correct on assuming it is a SA/DA design. It is not really a 4 pound trigger, it just seems a lot harder than it really is. I got a video with it . It shows how to strip a s&w auto but doesn't appear to be SPECIFIC as to model ! The directions DO work though. Maybe all S&W's are the same(??).

I know how too do this quickly, safely, and appropriately.
Take the 645 and completely unload it---safely.
Then hand it over the counter too a good smith.

  William, THIS was MY first thought. Finances being what they are make this a second choice at best ! Gunsmiths are quite hard to locate since the clinton years. There USED to be a dozen shops within a 10 mile  CIRCLE of my home, now there are NONE. Even the basement dealers have been moved out.

I can remember when a good friend of mine put his 645 in a Ransom Rest and shot some of his bullseye loads in it, he quickly traded the gun!

I had one years ago, and feel your pain. If you really love the pistol, take it to a gunsmith. Most triggers can at least be smoothed out if not shortened. I didn't have that great love, and sold it to buy a Colt XSE. Never looked back.
