Hello. I was wondering if anyone has put a heavier recoil spring in the new Springfield xdm 10mm and if it helped at all with how far the brass flys? I picked up the 4.5 inch model and after a new trigger from powder river i love this gun. Only issue is i am launching brass into outer space and im losing more brass than i would like.
Does anyone know what weight springs come in the xdm 10mm. I have seen it posted somewhere that it is 18 lb. I was thinking of trying 20 or 22 lb spring and see if it makes a difference.
Howdy
I'd be interested in finding this out too. Mine chunks brass pretty high and far. It lobs them over my brass catcher and into the next county. It's more of an annoyance than anything, but I hate losing brass.

Heres a link to the same topic i started over at the xdtalk forums for anyone interested.

I note reading the other thread it says the ejection pattern tightened up, but was still 15' distance. In my experience over many years with the 10mm in lots of platforms, the only remedy to this is to alter the ejector. But that does risk reliability issues.
15 feet and tighter would be better than spread out up to 20 sometimes 25 feet. If i could get an extra factory ejector for a reasonable price it would be interesting to experiment with.
all 10 mm firearms throw the brass into orbit. my personal solution to saving brass was to get one of those cheap foldable sun shades. my shooting spot is on the property I keep my boats & traps. I built a berm with my Bob Cat and we got a dry spot in the mangroves to shoot. (40 yds max) if there is a breeze, it gets blocked by the trees. so I wanted some shade for a while anyway. on the right side and part of the right rear side, I hung some old shade cloth with a 1x2 p.t. pine board stapled on the bottom for weight & stiffness. when shooting, I stand on the left side and all the brass is caught. I can put it up & take it down by myself. today I shot around 250 full house 10mm rds through my new XDM. ;D I recovered ALL of the brass! 8) before hurricane Irma took it away, my shooting bench had a 1x2 & shade cloth roof and right side. it worked ok but still a lot of brass made it to the bushes.
Currently I have the biggest tarp I could find at harbor freight in my shooting kit. I think it is 25'X40'. I shoot 2-3 shot and have my spotter watch the brass, then lay out that tarp so the middle is about where the brass fell and the front edge is about where I am standing.
This works fine for chrono and target work, but falls short for any dynamic drills where I practice against multiple targets. I like blaster's idea of a cheap sun shade. I have been waiting for costco to have them on sale. I plan to grab one and then install mosquito net walls to stop brass.
Tried a 20lb spring in my 4.5 today, was shooting 200gr @ 1200+ fps and 155 approaching 1350fps. Brass was thrown about 12ft opposed to 20-30 before. 100% function and recoil seemed to be reduced as well. Tradeoff is the slide is harder to rack, might be close to the max pull my wife would feel comfortable with. May try the 22lb spring next time out just to see the difference but 20lb seems good to me.
anyone know what weight the factory XDM spring is?

Since the 20lb spring was about 1/5th longer than the stock spring with the same dia base material, I'd guess the stock spring is close to 16lb.

From what I'm seeing the factory spring is 18#

Could be, wonder if the Wolff 20lb is on the heavy side to account for break-in, it feels greater than a 2lb increase on initial pull.
I just used my handy dandy recoil spring gauge on my 4.5" XDM's factory recoil spring and I came up with 20lbs.
I haven't fired a ton of hand loads out of it, but here are my brass-tossing adventures thus far.
1). Privi Part. 180g JHP (kinda wimpy load @1080 fps in a 5" 1911). XDM functioned fine. Brass ended up @8 feet to the 4 O'clock position.
2). PMC 170G JHP. Haven't chronological them but they have much more flame & punch than the PPIs. Advertised MV is 1200fps. Brass ends up @ 12-15 feet to the 4 o'clock position.
3). Montana 180g LBT, 180GR, LFN-GC in front of 12.9g AA#9, CCI300 spark plugs. Brass ends up @ 12-15 feet to the 4 o'clock position.

Wonder if they made a switch. The wolf 20lb spring was the same wire diameter but almost 1.5" longer than the factory spring in my XDM. I was actually worried that the slide would not be able to go far enough back. If you have a set of calipers handy post up the wire dia, spring dia and overall length. I will measure my stock spring when i get back home, can also provide Wolff 18, 20 and 22lb data as I bought the whole tuning kit.

Hey rockcrawler,
I measured my stock XDM spring and here's what I came up with.
The spring OAL is 6.085" on my 6" caliper (measured roughly 6-1/16" on a steel tape; only @1/4" shorter than a 5" 1911 spring I had laying around).
The wire diameter is .051".
Like you, when I first pulled the gun apart, I was surprised how long the recoil spring was, especially when placed next to a full size 1911 spring.
Are your aftermarket spring ends closed, squared and ground like my factory one is?
With further inspection, I'm also kinda concerned how thin the guide rod flange is. Makes me wonder how many full house rounds it will take before it cracks or splits.
Factory spring
Coil dia .512
Wire Dia .051
OAL 5.875
Wolff 18lb spring
Coil dia .512
Wire Dia .053
OAL 5.915
Wolff 20lb spring
Coil dia .512
Wire Dia .053
OAL 6.09 (Been compressed for a few weeks)
Wolff 22lb spring
Coil dia .512
Wire Dia .055
OAL 5.827
No part numbers on the individual spring bags, they all came in Wolff Recoil Calibration Pak #13226. Spring top/bottom are not ground (flat), full dia at top and bottom.
Any chance you could add the coil counts? With those four values and a guess at the kind of wire the theoretical spring constant can be calculated.

I was just going to add that coil count is critical not length.
Crap.
I forgot spring diam. tooo...
>:(
I'll get that and coil count on my stock spring later when I get home..
Recap: The spring OAL is 6.085" on my 6" caliper (measured roughly 6-1/16" on a steel tape; only @1/4" shorter than a 5" 1911 spring I had laying around).
The wire diameter is .051" (could it be .0515" or .052"; some coils seem to measure a little fatter than others).
.507" OD
.402" ID
26 COILS
Both ends are closed, squared and ground flat.
Ordered a 22 lb spring on monday. With any luck i will have it by this weekend and be able to try it out.

That should be about an 18 lb spring.

Bought one of those and got it today. I've got some light loads and some heavy loads to try it out with. If it runs the light stuff and doesn't throw brass from the heavy stuff into the next county, I'll be happy.

I tried out the new 22 lb Wolf spring, and it works pretty well. My gun is the 4.5" version of the XDM.
175gr lead at 966 FPS - most cases landed in a pile 2-3 feet away. I only fired 15 rounds, but they all cycled. I can't guarantee that light ammo like this will be 100% reliable, but I saw no signs of the gun struggling to run it.
175gr lead at 1070 FPS - the cases landed around 9 feet away, and were scattered around.
175gr lead at 1185 FPS - the cases landed around 14 feet away.

Is anyone using the wolff firing pin spring that comes with the recoil spring or just sticking with the factory fps?

I used the Wolff spring. I don't know if there's a difference though. It seems to work just fine.

I modified my 1911 spring gauge for the wider diameter XD spring, and you are right, it's 18#.
It must have been binding/dragging more than I thought...
I think I'll try a 20#.
Been a while but after much snow and cold my local range is now melted off and accessible. I had a chance today to shoot the xdm10 with 22 lb spring. I was very happy with the results. First i tried a minimum load of universal under a 180 grain hornady hap bullet. I wanted to make sure rhe gun would reliably cycle the wimpiest powder puff load i could think i would ever use. It did. No issues. Next i loaded up full house loads of longshot under the same 180 grain Hornady hap bullet. The cases landed about 10-15 feet away in a relatively small area. Thats about 10 foot less than with the factory spring. Recoil was not reduced noticeably but the recoil impulse seemed less sharp if that makes sense. All in all im happy and feel it was money well spent.
Hate to stir up an old ghost here, but something is screwy with my new Wolff spring.
it's supposed to be a 22#, their spring #54222.
When I first put it in, I was surprised how short it was compared to the stock.
when I got the gun back together, the force required to start the slide moving actually seemed less that the stock, but the thicker wire seemed to make up for that the more the slide moved rearward.
I fired a few 180 & 185 grainers through the gun and something just doesn't seem right (I used a backstop to catch the brass so I can'tcompare how far the brass would have flown vs. the stock spring).
I took it apart this evening (only been in the gun for 2 days and @30 rounds fired) and the new spring already has a little bend in it.
Compressing it to the same length as the factory spring on my gauge (@1.655") shows only about 17# on the scale.
Here's the specs:
5.230" long (almost 3/4" shorter than stock)
.515" O.D.
.053" wire diameter
27 coils
Doesn't seem like this is the right spring...?
Kinda bummed, I have a few hotter loads I need to test and the extra power sure would make me and my XDMs frame feel better.
John Andrews from Wolff Gunsprings emailed me back.
He said these are the dimensions of their 22# XDM spring (I assume when brand new):
Wire - .054"
End OD - .515"
Body OD / ID - .513" / .405"
Length – 6.5 inches long with 27.5 coils
They are sending me a new one.
Hope they get the new spring to ya soon. It made a noticeable difference in mine.

Hmmmm,
Just go the new spring from Wolffe and it appears to be the same/short one that I got from Midway before...
Only about 5-3/8" long on the tape measure.... Why so short?
Do you think somebody in the factory/distribution/packaging is mixing up the springs for the 4" guns with the 4.5" guns?
What else can it be?
JTracy, you are using the #54222 spring right? Is your 6+ inches long like the guy at Wolffe told me it should be?
You'd think they'd check this after me sending them the dimensions of the one I already had.
This is getting stupid. Maybe it's me?
The 22# Wolff spring for the 4.5" XDM is their shortest one for that platform at @5-3/8" long, but because the wire gauge is the heavier .054" they say that's the correct length. (I don't know why AZrckcrawler's spring measures differently with Wire Dia .055" and OAL 5.827"?)
I cannot get within 10% of that 22# on my spring gauge, which granted is not a super "scientific" gauge, but it sure shows the correct weights for 1911 springs.
So I figure I'm not compressing the #54222 enough, so with 27 coils at .054", I figure the max one can compress the spring (no space between the coils) is @ 1.458". So this morning, I run the spring down to that length and can barely get 20# on the scale
Talked to Dave, the GM at Wolff Springs, he told me that spring should reach 22# at 1.540" of compression which it doesn't.
He said he would check a #54222 out of their stock on their spring gauge and see what it reads and to call him back later today.
Springfield says all the 4.5" XDm guns are the same dimensionally, so it can't be that the 10mm is a different gun/recoil spring length, right?
Springfield also said to me that the factory spring is about 16#-16.5# which has to be a mistake, right?
What am I missing?
I feel like I'm in the recoil spring Twilight Zone....
When I put what is supposed to be a heavier than stock spring in it, I can feel the slide smacking the frame when I fire the gun.
