Orbit Posted September 8, 2015 Share Posted September 8, 2015 Friends, I am shooting both a factory load and reload for shooting IPSC. In your experience, what is the best recoil spring weight for the following pistols: 1. Glock 17 Gen 4 - I will shoot reload most of the time 130 pf 2. Glock 34 & 35 Gen 4 - I will shoot reload most of the time 165 pf. Right now, I am set-up in the following: 1. Glock 17 - Glock standard recoil spring (I dont know the spring weight) 2. Glock 34 - 13 lbs lone wolf recoil spring with stainless guide rod and reducer ring 3. Glock 35 - RYG Tungsten Guide rod (I dont know the spring weight) Please let me know your thought and suggestions. Link to comment Share on other sites More sharing options...
Nathanb Posted September 8, 2015 Share Posted September 8, 2015 For low power factor most will say 13. I've ran a 13 and an 11 in my 34 without issue Link to comment Share on other sites More sharing options...
bowenbuilt Posted September 8, 2015 Share Posted September 8, 2015 For anything approaching major PF I use a 15 lb. spring, any more than this and my guns will dip as the slide closes. A 13 lb. spring for Production or anything around 130 PF. Anything lighter and the gun may not go back into battery after a few thousand rounds on the spring and a dirty gun. This is what I have found, your experience may be different. Link to comment Share on other sites More sharing options...
bigtimelarry Posted September 8, 2015 Share Posted September 8, 2015 I use a 13 lb ISMI with Jager SS Guide rod in all my Glock 17 & 34 and that works the best from 128 PF - 145 PF for me. Sights settle perfect. Link to comment Share on other sites More sharing options...
Foxj66 Posted September 9, 2015 Share Posted September 9, 2015 (edited) Only thing I have to add is that my 17 did not like a 13 with the factory striker spring but it ran fine in my 34 with the factory striker spring. I am using ISMI flat 13 springs on the Jager rod for Gen4 guns. Edited September 9, 2015 by Foxj66 Link to comment Share on other sites More sharing options...
9x45 Posted September 9, 2015 Share Posted September 9, 2015 I run the OEM Glock 17lb for all my competition guns, without failure, for the last 23 years. And no issues. Link to comment Share on other sites More sharing options...
Bidah Posted September 9, 2015 Share Posted September 9, 2015 17 - OEM 17lb Gen4 dual spring setup. 34 - 13lb ISMI on a LW stainless rod. The OEM spring works fine for me as well. Both guns are used in Production and 3Gun. Link to comment Share on other sites More sharing options...
Philip Dedmon Posted September 9, 2015 Share Posted September 9, 2015 First of all I want to give my load data. 124 gr. @ 1075 = 133 pf G17 and 2 G34's I am using the ISMI 11 lb. recoil spring Link to comment Share on other sites More sharing options...
Orbit Posted September 9, 2015 Author Share Posted September 9, 2015 17 - OEM 17lb Gen4 dual spring setup. 34 - 13lb ISMI on a LW stainless rod. The OEM spring works fine for me as well. Both guns are used in Production and 3Gun. It is basically what I used this morning. Link to comment Share on other sites More sharing options...
Orbit Posted September 9, 2015 Author Share Posted September 9, 2015 This morning I went to our local range and tried my 3 glocks (17, 34 & 35) *Glock 17 - 17 lbs OEM -- zeroed in 10 yards with dawson precision fixed charger sight set *Glock 34 - 13 lbs Lone wolf stainless steel guide rod, after 15 rounds I stopped due to adjustable rear sight screw, I thought it was missing but it was actually a design if I am right (please see the pic below and give comments) *Glock 35 - RYG Recoil tungsten guide rod set - zeroed in 10 yards using the lone wolf barrel but using the OEM Glock Barrel, the shot is all over the place (max diameter is 8") Link to comment Share on other sites More sharing options...
3djedi Posted September 9, 2015 Share Posted September 9, 2015 most reliable is using stock...... but I use 13lb for .40 and 11 lb for 9mm Link to comment Share on other sites More sharing options...
ZackJones Posted September 10, 2015 Share Posted September 10, 2015 *Glock 34 - 13 lbs Lone wolf stainless steel guide rod, after 15 rounds I stopped due to adjustable rear sight screw, I thought it was missing but it was actually a design if I am right (please see the pic below and give comments) On my Glock 17 the sight adjustment is done on the right side of the sight as you hold the gun in your hand.

Orbit Posted September 11, 2015 Author Share Posted September 11, 2015 Thanks to all of you. I settled in the following: For Glock 17 - use the original recoil spring For Glock 34 - use the RYG stainless steel Tungsten guide rod For Glock 35 - use the 13 lbs spring in a stainless wolf guide rod It ran flawlessly.

Yankeejames Posted September 16, 2015 Share Posted September 16, 2015 I just setup my Glock 17 Gen 3 with a lone wolf guide rod and a non captured 15# wolf spring. Seems to work with 147 RN, 950 ft/sec, recoil is very controllable and still cycles the rounds. Link to comment Share on other sites More sharing options...
orangeman711 Posted September 16, 2015 Share Posted September 16, 2015 For the G17 at 130PF try a 13lb. spring with 2 or 3 coils removed. Good Luck. Link to comment Share on other sites More sharing options...
Jesster Posted September 24, 2015 Share Posted September 24, 2015 I am in agreement with most on here. for the minor loads a 13lb spring will work the best. I shoot a 35 with a PF of 170 and run a 15lb spring with a ss guide rod. best setup I have been able to put together. Link to comment Share on other sites More sharing options...

nwhpfan Posted October 4, 2015 Share Posted October 4, 2015 (edited) I run PF around 132ish in both a G4 17 and G4 34. I only use the OEM in the 17 because I only use it for GSSF. No problems, ever. With my 34 I shoot it in USPSA and I use a 13lb spring. Seems to help it run it a little flatter.... Edited October 4, 2015 by nwhpfan Link to comment Share on other sites More sharing options...
jlo86cj Posted October 13, 2015 Share Posted October 13, 2015 13# Wolff in my G34 gen4 with 128pf. Link to comment Share on other sites More sharing options...
Southpaw Posted October 13, 2015 Share Posted October 13, 2015 I normally use a 13lb. in my 34. I'm shooting a GSSF match in a few weeks so decided to practice with some stock Glocks. 17 Gen 4 and 17L Gen 3 with stock 17lb. recoil springs had really weak ejection with my reloads, 147gr @ 133pf. Brass was just dribbling out going maybe 1-2 feet, but no malfunctions. Link to comment Share on other sites More sharing options...
HeyChris Posted October 13, 2015 Share Posted October 13, 2015 I've switched to the new "Heavy" Jager Gen 4 steel guide rod with Wolff 12# springs and have really liked the feel on my G34 Gen4. Link to comment Share on other sites More sharing options...
spencerattix Posted October 13, 2015 Share Posted October 13, 2015 I run a Zev 14 lb with a tungsten guide rod in my G35. The 15lb ISMI was really stiff. Going to try a 13lb ISMI when this Zev is finished. The red paint on the Zev gets all over the inside..... Link to comment Share on other sites More sharing options...
