Taurus 24/7 OSS : Is it acceptable to take off the recoil spring loop and replace the recoil spring then reassemble or must I purhase a full assembly each time the recoil spring needs to be replaced?

I typically replace my recoil springs every 3,000 rounds.

Is this necessary? If so, I'm way over due.

3,000 rounds seems way too short. 300,000 would be more like it.
Did you ever actually measure the performance of a spring with 3,000 rounds vs. a new spring? It wouldn't require much technology - a ruler and a scale.

I have broken many Berettas at 5,000 rounds cracked frame, locking block, trigger bar etc.. I have had the guide rails separte from a Glock at 6,000 rounds and a barrel lug broken on an H&K at 10,000 rounds.

With that said I believe in preventative maintenance and the minimal cost of a recoil spring is nothing. At 5,000 rounds on numerous Berettas you will see a difference in length of 1 to 2 inches consistantly. The other springs were casptured and the disatnce that the empty cases were ejected was in some instances twice as far as with a new captured spring at 5,000 rounds. No measuring devices were necessary. In one way or another it was all very visual and the felt recoil is considerably more.

I have seen 30,000 and 50,000 recorded rounds out of Berettas that had a recoil spring changed every 3,000 rounds. I have changed my H&K recoil spring every 3,000 rounds on my H&K and have 11,000 rounds through it with the only problem being a broken trigger spring at about 10,500 rounds.

well thank goodness you finally got a quality pistol that doesn't need all that maintenance!-LOL
The OSS was designed for the military test trials and so is basically a tank, but its your pistola and so you can swap parts as much as makes you comfortable.
Welcome to the forum and enjoy the OSS.

Thanks for the welcome, but I still need to know what to do with the recoil spring change. It looks as if it may not come as a captured unit and that the recoil spring can be swapped out by removing the recoil spring loop putting on a new recoil spring then securing the recoil spring loop again.

When I was looking through the expanded parts diagram the three components of the recoil spring are all numbered seperatly. When I call to order parts the people that I speak with only know the parts and cost and not much else.

I will probably order all thre parts and go from there, I think I just answered my own question. I will give an update when my parts arrive.

Caliber???

3,000 rounds seems a bit soon for any caliber. I would go at least 6,000 rounds for any caliber. I've gone 8,000 on .45's and 10,000 to 12,000 on 9mm's but the latter may have been a bit much. It also depends upon what kind of Ammo you've been feeding your Pistol a steady diet of.

It's really hard to put a number on when you should change out a recoil spring, but it should be done if you feel your slide is impacting the frame too much or before that.

I would give Wolff Gunsprings a call and see if they know how to disassemble that captive spring/guide rod assembly.

For the .45 ACP 24/7 OSS, the Factory Spring is rated at 18 lb.s For the 9mm 24/7 OSS, I would use a 15 lb. recoil spring. For the .40, you're on your own, but I would guess 16 lb.s

When I had to order a new captive spring assembly yesterday (BRAND new out of box, the button on the end was broken) they acted like it was all made together, spring held on by button.

I ordered a full set for my PT 145 at the same time that I needed to order the teeny FP return spring that magically dissappeared. I was going to wait on the install of the "not immediately needed" springs, but put them all in as I bought the pistol used with no idea of it's history. The recoil spring comes from Taurus as an assembly (not that expensive)...others here have replaced only the large and/or small springs from Wolf and you can find their threads in the forum. I just changed out my PT 1911 spring after some 7,000 rounds on that pistol.

Would seem a shame to throw away the all steel full length guide rod on a 24/7 OSS just to replace the Recoil Spring. But then again, maybe the factory does not want us messing around with different spring weights.

I've heard some of the 1911 "experts" say to replace the micro 1911 recoil springs at 1,500 rounds, so 3,000 on your 24/7 OSS doesn't sound that far out of line. As long as it helps you, it doesn't matter what others think. In any case after the first replacement you will have a definitive answer as to what needs to be replaced.

BTW, in the SOCOM RFP for a new high cap .45 Auto, the OSS was, according to insiders, leading the pack in reliability and I think they were firing something like 30,000 rounds through each pistol in the competition.

They shot 10,000 rounds through that 24/7 in Nevada to set the speed steel record and never made any mention of having to replace anything.
I wish I had the resources like some people out there to be able to shoot the kinds of rounds per year you all talk about. Fact is I have neither the money nor the place to shoot that much. I guess I'll never have to worry about having to replace a recoil spring to that end.
