ParaJoe Posted June 13, 2006 Share Posted June 13, 2006 I wasn't sure if this was the place being as I am talking about springs or if it should have gone in the Glock forum, but if I'm wrong someone will move it. Anywho, I busted my factory guiderod in my G22 and bought a stainless steel one to replace it. Along with it I bought a 13lb and 15lb ISMI spring. I put the 13lb in it and ran about 50 rounds through it no problem. Same with the 15 pounder. I liked the feel of the 13lb better. Which one should I use? The 13 or 15. Sorry, I'm new to playing with springs. JOe Link to comment Share on other sites More sharing options...
Sean Gaines Posted June 14, 2006 Share Posted June 14, 2006 i guess you were pretty lucky to be able to get a 13lb to work in a 22, most of the time it takes a 15lb, on my guns its the 13lb for the 9mm and 15lb for the .40 cal. Link to comment Share on other sites More sharing options...
Chris Keen Posted June 14, 2006 Share Posted June 14, 2006 If your 13 lbs spring works for you , then by all means use it. It WILL feel better. Use it for as long as it works for you. I cant get anything less than 15 lbs to work in mine. Link to comment Share on other sites More sharing options...
ParaJoe Posted June 14, 2006 Author Share Posted June 14, 2006 (edited) Well when I put the 15lb spring in it was REALLY long. Right around an inch and a quarter longer than the 13lb'er. It also smashed when the slide went all the way back. From what I interpreted through the vast amount of info on this site, smashing the spring is bad. So I ended up hacking off four coils, one at a time, until it fit in there without binding (I think that's the term.) It then felt the same as the 13lb spring when racking the slide. But not when shooting it. Please correct me if I am wrong, have ruined my 15lb spring, or am being a moron. Edit.. I didn't chop the 13lb. It worked like a champ.

JFD Posted June 14, 2006 Share Posted June 14, 2006 I'm running a 13 lb spring in my G35 for both major and minor loads. Link to comment Share on other sites More sharing options...
cmzneb Posted June 16, 2006 Share Posted June 16, 2006 I tried both 13# and 15# ISMI springs in my Glock 34 and Glock 35. They shoot softer, but the trade off in reliability was not worth it for me. After a couple malfunctions in matches I finally realized that the stock guide rod is the best. Gun works every time! Link to comment Share on other sites More sharing options...
jessej Posted June 17, 2006 Share Posted June 17, 2006 Use whatever feels best for you and runs 100%. I run a 13 pound ISMI no problemo. Link to comment Share on other sites More sharing options...
Harmon Posted June 17, 2006 Share Posted June 17, 2006 its MHO that anything under 15 pounds is too light for a major load in a glock. at 15 pounds, the spring doesnt last as long and the brass gets ejected "muy alto!" Link to comment Share on other sites More sharing options...
norbs007 Posted June 18, 2006 Share Posted June 18, 2006 I use a 15 lb. spring with 3 coils cut on my G22. Shoots good with factory 180gr and my 4.7 gr. Titegroup 180gr bullet load. Link to comment Share on other sites More sharing options...
ParaJoe Posted June 19, 2006 Author Share Posted June 19, 2006 Well I shot a match today with the 13lb spring and it worked like a champ. I like it a lot. JOe Link to comment Share on other sites More sharing options...
Joe D Posted June 19, 2006 Share Posted June 19, 2006 I run a 13# ISMI with a couple of coils cut for major and a 10# spring for minor in my G35. Never had a problem with either. Link to comment Share on other sites More sharing options...
pbosik Posted July 8, 2006 Share Posted July 8, 2006 i have a ismi guide rod and 13 and 15lb spring, the 13 seems to not fully go into battery, the 15 with minor loads seems to barely eject the cases and i have had jams with both. it is a glock 35..now i am unsure myself. should i go back to the factory setup?

DaG Posted July 9, 2006 Share Posted July 9, 2006 I run a 13# ISMI with a couple of coils cut for major and a 10# spring for minor in my G35. Never had a problem with either. How light is your striker spring? DaG Link to comment Share on other sites More sharing options...
pbosik Posted July 9, 2006 Share Posted July 9, 2006 hi big D.. the striker and spring are stock..will the lighter recoil spring eject farther or is it the heavier? i cant remember... Link to comment Share on other sites More sharing options...
smokshwn Posted July 9, 2006 Share Posted July 9, 2006 I ran a 13lb spring in my g35 with no problem for both major and minor loads. I liked the feel very much. Good luck, Craig Link to comment Share on other sites More sharing options...

If I let the slide go lightly on mine in won't go into battery with the 13lb spring. It needs force or the speed of it slamming shut when firing to work. I'm shooting a G22 so I cannot directly to your problems. Did you cut any coils yet? Joe Link to comment Share on other sites More sharing options...
Stuck in C Posted July 22, 2006 Share Posted July 22, 2006 I used a 13 lb spring and reduced power striker spring in my G34 for 3 years, but it only ran about 98%-one or two light firing pin strikes in every 100-120 round match. I liked the way it felt but it just was not reliable enough. The 13 lb spring with the stock striker spring failed to go into battery at about the same rate (once or twice in 120 rounds). Iv'e now gone back to both springs stock-100% now. But, I shoot limited major with a G35 with 15 lb recoil spring and reduced power striker and it runs perfectly. So whatever works for you.

dskinsler83 Posted June 5, 2011 Share Posted June 5, 2011 Moderator note: merged threads What is better for major power factor .40 in a glock 35? Heavy spring like 20# or lghter like 15#??? I feel like the 20# spring is really beating my hands up Link to comment Share on other sites More sharing options...
McGlock Posted June 8, 2011 Share Posted June 8, 2011 Correct me if I am wrong.. But the 17 pound springs(stock) were used for high power ammo like law enforcement jhp ammo that has a power factor of 180 plus.. So I see most guys going less.. I've seen 15# and as low as 13# in limited glocks.. Link to comment Share on other sites More sharing options...

C.W. Posted August 31, 2011 Share Posted August 31, 2011 I currently use an ismi 13 pound spring on a stock glock guide rod with a lightened trigger spring (vanek)in my glock 35 - shooting minor pf loads (IDPA is the only game available to me). It works 100% - with federal primers - light strikes 1-2 out of 100 with winchester primers. I just spent a session with my bone - stock out of the box g27 with the same load (180g berry's 2.9g clays) and it was 100% for 400 rounds. When I first started using this load with the g35 and a standard trigger, it was 100% with 17,15, and 13 pound springs. The 13 just "felt" best. Anyway, I wonder if the fast powder/heavy bullet combo might be a factor in making the gun more reliable through the range of different spring weights. (maybe a sharp jolt at the beginning of ignition makes the slide more repeatable than a steady push?) Link to comment Share on other sites More sharing options...
