Maintenance

I've been shooting my PM9 a bunch since getting it in February and have around 1200 rounds through it. All I've done is field strip, clean and relube. When should I replace the recoil spring? What do I replace it with? When do I need to detail strip it? Still new to 1911s and all their special needs.
Thanks,
Jeff

The general rule of thumb is to perform a detail strip/clean when you hit 5000 rounds. I would replace the recoil spring at 2000 rounds with a chrome silicon offering from Wilson combat, I believe DW uses a 10lb spring for full-size 9mm. You could also try a 12lb recoil spring.

We also use and sell only Chrome silicon recoil springs. On a full size gun you should be good until 2,500 rounds. Technically, you can probably go, quite a bit longer being Chrome Silicone springs but I like to error on caution and springs are relatively cheap.

Keith, what would you recommend for a Vbob in 45acp?

Can I use a full sized flat wire spring from wilson combat?

Spring weights are all listed in the above thread^

You can use a flat wire spring but you'd need a new guiderod to do so. I have one in my Wilson and if it didn't come with it when I bought it I wouldn't be using it.

Thanks for the link CT

So by that guide I would need a #20 spring for my VBob. These are rated for 10mm and 45acp +P, is this correct?

The Wife's PM-9 was easily over the 2500 round mark last fall when I changed her spring "just because". It was running fine but we had some major matches coming up so I changed it with another chrome silicone 10lb. Like Keith says, springs are cheap.

I have always changed recoil spring before they hit 3000 rounds.

I also would like to know about WC flat wire spring with the WC guide rod kit.
For 9mm DW Specialist. It is stated 40.000 rounds
Anyone may confirm that statement? Thank you.

Think I'll just get springs from Keith. I like the way it shoots now. Looks like the Wilson flat wire guide rod requires a paper clip for disassembly. I like how simple my PM9 is to field strip. I do need a bushing wrench, but that's a good thing!

I lube before each shooting session, field strip and clean every 1000 rounds, and detail strip and clean every 5000 rounds. I change the recoil and firing pin springs every 3000 rounds.

You may not need a bushing wrench if you push the slide out of battery and then turn the bushing. One of my Valors is like this while the other is snug, but can be turned by hand in battery.

Some of you folks are way nervous ... do you wrap your kids in bubble wrap so they can't hurt themselves ?? 1500 rounds on a new gun and I am reading about replacing parts cause they will be worn out ????

I bought a colt series 80 and have fired better than 85 thousand rounds thru it. The sights flew off a couple times and the extractor got replaced but generally I cleaned and oiled and kept shooting it.. these guns survived battle on Japanese islands and sand and abuse and kept working... they ain't made out of balsa wood and duct tape..

I have fired 1200 rounds in one long day at the range and I thought my hand would throb and be in pain for a week... but I never thought about time to start replaciing parts..

Wilson flat wire guide rod not required a paper clip, if you use GI system guide rod.
FLGR system requires paper clip.
WC flat wire spring will be feat on both systems GI and FLGR.

Not paranoid, just planning ahead. Guns are simple machines, but parts wear out and need replacement. I just wanted to know what to expect. Quantico, when do you replace the recoil spring in your Colt? Do you shoot it until it malfunctions? Just trying to learn.
Thanks,
Jeff

Thanks for posting. I was wondering why changing all these springs. I have 3 glocks with thousands of rounds through each and have not had to change anything on them. They still do what they're supposed to do.

I don't own a Dan Wesson (yet) but still own my Kimber that I bought back in 2000. Shot about 20,000 rounds of 230gr 45ACP FMJ so far and have yet to change the stock recoil spring. Pistol shoots fine.

To the OP:

When you field strip, do you take out the extractor and the firing pin spring to clean the channels? You don't have to do this every time you do the "normal" field strip, you should do it after a few hundred rounds. Also, after about three thousand rounds, you should replace the firing pin spring.

All flat wire recoil springs, require a .250" FLGR. We use these in our ECO. The benefit of the flat wire spring is that it will generally last 10-20 times longer than conventional, music wire, coil spring. Mainly because there are more coils and the material it is made out of.
Why don't we use them in all of our guns? Because people, generally, like to keep the 1911 as true to form as possible. We don't do that with the Officer sized slide because a conventional spring would only last 500 rounds in the officer slide.

In general, I recommend changing your commander length springs every 2,000 rounds.

KYJ,
Have not removed the extractor or firing pin yet. More stuff to learn how to do. Thanks for the tips.
Keith, thanks for your input. It's great to know that the big kahuna at DW interacts with his customers on a regular basis. Makes me feel even better about buying one.
Jeff

I changed the recoil spring at about 50 thousand rounds.. maybe 1993 or so.

I own at least ten 1911's and most of them are wearing the parts they came with. The exceptions are a colt custom for IPSC and norinco I built for my daughter myself. Ed brown still has its orig parts, les Baer still has orig parts , both colt delta elites are stock except for flat metal checkered MSH and new slide stop and thumb safety that I installed.

I don't mind changing out fire control parts and such , but not because things are worn out. And I save every piece in case I want to return to stock pistols..

By the way I learned how to fully take apart a 1911 with a colt with about 50 thousand rounds. Never had the extractor out or firing pin until then, never had removed the hammer or sear or MSH until then. Zero gunk inside and nothing that looked bad in any way. I did note some extractor wear and replaced stock colt with a Wilson bulletproof part. I learned how the gun worked by looking at all the wear marks on the pieces. Great learning experience.
