eric nielsen Posted October 28, 2003 Share Posted October 28, 2003 I tried a guy's Glock a week ago: he had tightened the slide-to-frame fit to almost no rattle at all. I liked it, the result was a very consistent trigger pull. You can simulate this by pushing down on your slide with your weakhand thumb as you dryfire the gun. Now the trigger parts do not have to yank down your slide in order to release the striker forward. This shooter said he had done this by gradually hitting the steel rail inserts in the frame of the gun, which is the way that makes the most sense to me. Elsewhere I've read of people marking the slide in four spots and hammering on the slide of the Glock instead. Which is the best way? I really don't want to crack any part but I fear messing up the slide a lot more. Any input is greatly appreciated. Link to comment Share on other sites More sharing options...
Flexmoney Posted October 28, 2003 Share Posted October 28, 2003 Here is an article which includes tightening the rails. http://www.sportshooter.com/gssf/dalerhea_dremeling.htm It might be a good idea to use some "slide fitting bars" so that you don't go too far.

tightloop Posted October 28, 2003 Share Posted October 28, 2003 Got to be careful not to crush the frame in the vice when you secure it... Link to comment Share on other sites More sharing options...
eric nielsen Posted October 29, 2003 Author Share Posted October 29, 2003 Yeah, the guy who tapped on the frame inserts said he didn't use a vise, just rested the magwell on his bench. I've seen the Dale Rhea article and that way scares me. I wonder how CGR and JP do theirs. Link to comment Share on other sites More sharing options...
EricW Posted October 29, 2003 Share Posted October 29, 2003 I've seen the Dale Rhea article and that way scares me. I wonder how CGR and JP do theirs. Tapping on the frame rails would scare me far more. The slide is surface hardened, but a few thou below that - it's just regular metal. The rails are probably surface hardened as well, but just by virtue of the thickness much more of it's total thickness is hardened than with the slide. i.e. Banging on the frame rails sounds like a good way to crack one (or start a crack) and end up buying a new frame. My 2 pesetas... Link to comment Share on other sites More sharing options...
Garrett Posted October 29, 2003 Share Posted October 29, 2003 With the recent problem Glock has had with some production runs cracking frame rails, I would stay away from the frame. Link to comment Share on other sites More sharing options...
eric nielsen Posted October 29, 2003 Author Share Posted October 29, 2003 Thanks for the replies. I'll probably just leave that idea in the daydream dept... Link to comment Share on other sites More sharing options...
tightloop Posted October 29, 2003 Share Posted October 29, 2003 Glocks just do not lend themselves to easy or simple frame modifications like any gun with a metal frame. Got to take the bad with the good. Link to comment Share on other sites More sharing options...
Jim Taylor Posted November 20, 2003 Share Posted November 20, 2003 Here's how I tightened one of my G17s up. Mike rear frame rails. Add a little for clearance, say 0.002". Find a hex key or some other steel part (I used a file) of appropriate thickness. Mark where slide and rear frame rails interface when in battery. Remove slide and insert hex key or other part identified above. Peen with a ball peen hammer. You'll have to hit it like you mean it. When hex key is tight, pry out and do other side. Results will be lighter trigger pull, and some increase in accuracy (although hard to quantify). It's not hard as long as you don't have a personal attachment to the slide and watch your fingers.

Custom Glock Racing Posted November 20, 2003 Share Posted November 20, 2003 . I wonder how CGR and JP do theirs. I dont do it as it is not neccesary. Link to comment Share on other sites More sharing options...
