RobMoore Posted August 30, 2007 Share Posted August 30, 2007 I'm in need of some detailed directions on how to fit a new recoil spring to my Glock. I looked at the spring FAQ, and found plenty of advice given on 1911 based systems, but nothing that applied to a glock with a non-captured steel rod and ISMI spring.

vrmn1 Posted August 30, 2007 Share Posted August 30, 2007 There is no fitting, you take the old one out and put the new one in. Link to comment Share on other sites More sharing options...
Aircooled6racer Posted August 30, 2007 Share Posted August 30, 2007 Hello: You may have to cut some coils off of the ISMI spring. Make sure the new spring does not go into coil bind. I had to cut off 2 coils on my 13 pound ISMI spring. Thanks, Eric Link to comment Share on other sites More sharing options...

You just need to make sure that the steel guide rod is made for your ISMI spring. I bought a Lighting Strike rod & my ISMI Spring would not fit!

Coolduckboy Posted August 30, 2007 Share Posted August 30, 2007 i am wondering too. I bought a 15lbs recoil spring and felt heavier than my stock spring. I just got a 13lbs recoild spring in and going to play around with the coils but don't want to cut too may off. Link to comment Share on other sites More sharing options...
Scout454 Posted August 30, 2007 Share Posted August 30, 2007 Take the guide rod out. (You can leave a stock guide rod/spring installed it's just easier to do without it in place). Pull the slide all the way to the rear and mark the frame and slide at some point as a reference. Put the new guide rod/spring in and see if the slide retracts fully. Essentially the same thing you do with a 1911. Link to comment Share on other sites More sharing options...
ParaJoe Posted August 31, 2007 Share Posted August 31, 2007 Which model is it going into? I have used the ISMI springs with a SS guide rod in my G22 for a while now and don't chop off any coils. The one time that I didn't like the way it felt. 13,15, or 17. I don't chop them and they last about five to seven thousand rounds. They aren't bad when I change them, but I makes me feel good.

RobMoore Posted August 31, 2007 Author Share Posted August 31, 2007 Using the above mentioned technique, mine fit fine without the need to remove coils. Thanks for the info, though, in case it needs fitting next time. Link to comment Share on other sites More sharing options...
