Comments on: S&W 625 Update http://gunnuts.net/2009/07/09/sw-625-update/ Gun info by shooters, for shooters Sat, 11 Feb 2012 07:02:16 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: Homer http://gunnuts.net/2009/07/09/sw-625-update/#comment-11867 Homer Fri, 10 Jul 2009 11:57:56 +0000 http://gunnuts.net/2009/07/09/sw-625-update/#comment-11867 RE: removing the SA notch - other than making the gun impossible to fire SA, it does almost nothing to trigger pull or function, save slightly smoothing the last tiny bit of DA. When firing in DA the hammer doesn't come back quite far enough to engage the SA notch, but removing the notch and polishing the hammer at that point eases drag a tiny bit right at the very end of the stroke. A note on hammer spring tension: sometimes a gunsmith (or gun owner) will back out the hammer spring tension screw in the grip frame to ease spring tension and make the gun run smoother and trigger pull lighter. That's an excellent way to test it to get the right spring tension, but the correct method of achieving that is to remove metal from the end of the tension screw so it can be screwed in all the way to remain tight. Anything else - including loctite - will eventually let the tension screw start backing out. If you're going to do it yourself, buy two extra tension screws, and start filing one down .010" at a time. When you get the dreaded "click" instead of a bang measure the screw, and file the second one down to .025"-.030" longer and put it in tight. Keep the original tension screw in a safe place because you may need it if/when you change out hammer springs.

I'm curious what the purpose is behind the SA notch change. I have the same question as Weer’d. I’m curious what the purpose is behind the SA notch change.

Will it allow you to slamfire it from the hip to shoot WICKED FAST? Does taking off the SA notch effect the trigger pull or any other function of the gun?

Will it allow you to slamfire it from the hip to shoot WICKED FAST?
