M&P 2.0 compact spring issue

While I was at it I found one on EBay that says it's for the compact 1.0, but micrometer measurements show it to be 2.5", same as in the 2.0 3.6" so I went ahead and ordered it. Be cause of my NRA defensive pistol course coming up next weekend. We will see. I also checked mine after 200 rnds today, without removing it from the slide, and it appears to still be seated fine. I guess I will carry the extra in my range bag so I'll have it if/until needed.

Not on mine.
From the wording, I'm hearing you say you twice broke a piece off the spring during cleaning, not firing.

The obvious question is: How are you cleaning your gun in such a manner that you're breaking chunks off your recoil spring?

Uh......what I'm getting is the breaks were discovered during cleaning, not caused during cleaning....:rolleyes:

If you read the other thread, you'll see I mic'd the RSA from the 1.0 Compact and the one from the 2.0 Compact. There's also a picture of the two side-by-side. The 2.0 RSA is clearly longer.


The 1.0 Compact RSA worked in my 2.0 Compact for 100+ rounds without malfunction before my 2.0 RSA came in. I'm not sure if it's a good long-term solution, but it seems to work in the short term.

I tried to,look at your photos but this forum wouldn't let me. Could you post the two rsa together pic here? I also find this forum very hard to use. No notification of new comments on threads I've participated in. I literally have to go to my profile, find my content go to that and then see if anyone posted anything under that. Not very user friendly compared to other forums I belong to. Maybe I'm doing it wrong?

If that doesn't work for you, drop me a PM and I'll email them your way.
 
Thank you. So it appears the one is for the 3.5" barrel compact 1.0. Well damn. I have an email semt to S&W so hopefully I'll get the right one I need sent to me. I told them I'd even pay them for it. Thanks again.
 
I just don't understand how that spring can come off the end of the guide rod! The end of the spring is captured by the front of the slide during use, and doesn't even contact the end of the guide rod.

It is either wound too loose, or just plain defective in heat treating, and spreading during use. I sure hope the new ones they are sending out are "fixed!"

A puzzlement, as Pooh would saY!

I've found that the easiest and most effective way to clean an All Steel RSA is to simply hit it with brake cleaner. There is enough pressure to blow everything away and it evaps instantly and leaves no residue. Done. I've been cleaning my M-60 innards that way way since I bough it new in '83.

Exactly. There is no need to wipe the guide rod, hence no need to manually compress the spring. Guide rods and recoil springs do not need to be squeaky clean because their operating clearances are huge. If you insist on cleaning the spring assembly, spray it down with brake cleaner nd let it dry. Drip a drop or two of oil onto the rod and be happy.
PS: I don't think the OP broke his spring. Chances are it was defective when assembled at the factory. Probably cracked during the forming process. Those thin section wire springs worry me. Stronger in torsion, but weaker in bending compared to round section springs.

Never got a reply to my email, but a call to S&W M&P division customer service today got me a replacement RSA coming in the mail. As posted elsewhere was told if it happens again to send in the firearm. Hopefully it won't.
 
I sent S&W an email last Thursday, about the spring, got a confirming email from them the next day, and got a new one from them yesterday, which was Wednesday! Less than a week! I call that good customer service!

Awesome. Now go shoot that puppy.

Shot my new spring yesterday and all was well. Spring was intact when I field stripped it afterwards.
 
I really, really like my 2.0 Compact. I paid $310 shipped after the rebate and I will gladly spend a bit more if there is a highly recommended aftermarket recoil spring.

For a second I thought I had missed a part of this conversation where someone was shooting puppies. [emoji23]

I always just say, "shoot it until the parts rattle."

My spring also broke. Brand new 3.6" received 8/17. been to the range twice. Maybe 200 rounds or so. I'm pretty sure the spring was fine when I first received the firearm. but when I went to clean it this morning, I noticed the end was broken off and floating around the guide rod. I'll try to attach a picture.

Called S&W and told them, and they said they would mail me a new one. They didn't say it was a known problem, but they also didn't ask a single question about it and the phone call only took about 3 mins which was mostly me giving my address.

Wo can someone tell me, other than length, is the rod end retaining the spring different between the 4” and 3.6”?

I just find it difficult to believe that there is no issue with the 4” guide rod spring but now there are several reports of problems with the 3.6” spring. Is there that much more stress on the spring for the 3.6 since it has to do the same amount of work in less distance? Maybe that is just enough to exceed the strength of the rod spring end cap???

Disappointing as I bought the 3.6 to carry a lot and home defense. Now I have to womder about the long term integrity of the guide rod spring. Makes me womder of I should ask for a replacement to have on hand. Or wait until they fix the manufacturer defect in the spring.

I understand there will always be a small manufacturer failure rate. But the 3.6” model has not been out long and we already hace several reports of fsilire. They have not made that many of the 3.6” relatively. So the failure rate seems much higher than what would be expected for “normal” statistical failure rate.

Is my spring becoming an issue?

With all the postings regarding the RSA for the 3.6, I inspected mine. The pistol was purchased 8/20, and only has about 150 rounds through it (all flawlessly) so far.

If my pictures are adequately legible (and actually loaded) ... do I have a problem?

I have not even shot my 3.6”. Hopefully this weekend. Also bought mine early august and recieved ankut mod-august

My RSA looks about identical to the pictures above.

Seems to me that the forward end cap for lack of a better word is minimal at best with very small area for end spring coil retention. Seems lome a short stub the inserts i to the slide and then a disk (similar but smaller diameter to the rear RSA slring end) to withold the spring would be a better design. Or at least I woild feel more comfortable that the spring won't “unclip” from the front end indentation.

No, you do not have a problem.

I just inspected the RSAs on all my M&P guns. A couple look like yours and I haven't had any issues with them in a few thousand rounds.

When in the gun, the spring is held in place by the slide. That nut on the front of the guide rod isn't even touching the spring when the gun is fully assembled. It will only press on that nut when removed from the gun. Even if it were to slip past the nut, that would only happen when out of the gun so, the gun will continue to work.

If it did actually slip past the nut, S&W will replace it for free.
 
Thank you Rastoff. I feel better about the situation. I have been very fortunate with all (the few) of my firearms in that I have not had any mechanical failures - so far. Thanks again.
