The G 36 recoil system...

    It sure looks like the Recoil Master system in STI pistols. For those who know, just how close are the two different systems?

    The effort needed to move the slide assembly to the rear seems to be measured in poundage. What is the poundage ratings of the dual recoil springs in the G 36 system?

    Usually, it seems that recoil springs in short/fast moving slides need replacing more often. If true, how long do the springs on YOUR 36 last before giving up the ghost?

    My G36 is my primary carry gun, not my shooter. I run a few rounds to stay sharp so no issues with the springs. Interesting query though.

    I had about 5k rds through mine, used it for my carry gun and it just started to sh%t the bed. FTE FTF, seemed like a spring issue. I had a Glock Armorer clean it and I put in a new Stainless guide rod / spring system from B-T Premium guide rods. Same issue. I put the same rods in my G 30 SF with no problems what so ever. I love this pistol, but cannot carry it again until I get a good 500 rds through it with no issues.

    Any thoughts on this?

    FWIW, I am a retired SF Officer and have been shooting for quite some time, Gunsite grad, so let' stay away from the limp wristing issues.

    Did you try new MAG springs?

    I tried new mags, springs, with and without the Pierce extensions. I think it is a recoil system issue as the factory guide rod has dual springs and well we all know how that has worked out.

    I was going to look for a solid guide rod and try that out. I have pix of the typical malfunctions if that will help.

    What ammo type? I had 5 double feeds in my 36 in its first 500 rounds.

    Changed target ammo type and zero failures of any type in 1000 rounds.

    Any issue I've EVER had was with cheap range ammo... never with a quality HP ammo.

    I am thinking it may be the recoil system as it seems to be more prevalent with remans (factory reloads) and blazer. I did however shoot over 2500 rds of wolf through it with out a hitch. I tried new guide rods mags everything. I am thinking of sending it back to glock, but it does not always do it, maybe 100 rds are fine and then 3 rds out of the next 15 FTE or FTF. The cheaper ammo may not be allowing the gun to fully cycle, causing the slide to short stroke.

    I am thinking of trying 500 rds of speer gold dot to see if that helps. The damn thing shot flawlessly for the 500 - 1000 rds the previous owner may have fired and I put at least 4k rds through it. This is very frustrating.

    Salty, sorry for the hijack

    Fast eddie,

    No hi-jack.

    Slight diversion but still tracking.

    If I read right, after more than what might usually be considered a high round count for short slide pistols, you replaced a misbehaving OEM recoil system with aftermarket parts. Yes?

    Those aftermarket parts still didn't play nice.

    Just me, but I'd have gone in with OEM stuff.

    Sometimes when we trick out our favorite blaster, the tricks on us.

    Good point. I have an OEM from a second G 36 I bought after the first started to go poopoo. I replaced them both when I replaced the one in the older (EDC) gun. I also replaced the one in my G 30, but no issues there.

    I will try going back to the OEM guide rod and shoot a few hundred rds of speer gold dot ammo. If it passes the test, I will put it back in the line up.

    Any updates on this? I may be seeing similar issues with my 36...:crying:

    Last week I shot two boxes of Blazer and Two Win White Box with out a hitch.

    Yesterday, I shout 100 rds same type of ammo and I had 10 malfunctions in 100rds.

    I think that is sage advice. My Glock Armorer told me to get OEM parts and try that. Looking now for parts. Thanks for the note.

    Thunder do you have pictures of your malfunctions?

    Here are some of mine...

    The second one is a failure to feed, its a live round the first one is a FTE, it has been fired (I think you can see the primer having been struck)
