16 Pound Recoil Spring - XDTalk Forums - Your HS2000/SA-XD Information Source!

Is there any problem with using a 16lb recoil spring on a 45acp Tactical with standard loads ? By standard I mean 230gr bullets at about 850fps. 16 pounds is standard on a 1911, but I don't know if the slide mass or some other factor(s) are different enough on an XD that a 16lb spring would be too light.

I think the standard recoil spring on an XD45 Tac is 18#, I went with a 20# spring (along with Don's Fat Guide Rod) and that combo works very well.

I'd suspect the 16# may be too lite (i.e. throw brass a looong way), but I'm sure others will reply who've tried that.

I thought the stock weight on the XD-45Tactical was 20 or 21lbs recoil spring. I am running an 18lbs spring with my XD-45 Tactical and Don's skinny guide rod I have run both full power factory and my lighter reloads (as low as a 139PF) and it has run very well for me.

With a 1911 you can run a lighter spring than you can with a XD for two reasons. First during recoil you have both the recoil spring and the main spring (the spring that drives the hammer) in a 1911 resisting the slides rearward motion. In and XD you only have the recoil spring. Second you must have a stiff enough recoil spring in an XD to hold the slide in battery against the strikers spring, this is not an issue in a 1911 since the hammer is not mounted on the slide but the frame and thus the hammer spring does not try to push the slide out of battery the way a cocked XD striker does.

By doing a quick search on the forum, I'm 99% sure the stock recoil spring for the XD45 Tactical is 18#.

Are there different striker spring weights available too, or pretty much just the stock striker spring weight ? I would imagine a lighter striker spring would give you a little more leeway with the recoil spring weight (with respect to keeping in battery) as well as slightly lessening the weight of the trigger pull. Can't go too light though or ignition problems would crop up.

The power factor of your ammo will play a role. I use a 14# Wolff spring for shooting my IDPA loads (200 g at ~730 fps). With the full strength spring these will not extract reliably, not enough oomf to cycle the slide all the way.....

A lighter striker spring will only put you at risk of light primer strikes. It will do nothing to the weight of the trigger pull, since the trigger does not push the striker back...it only releases it. The XD is a single action.

well it does push it back a very small amount. put your finger over the cocking indicater and pull the trigger slowly and you can feel it move out wards if you look closely you can see it also.
so even though it is just a little bit a lighter spring would lower the trigger pull a small amount how ever not very much

You must be shooting ESP.

This is what I referring to. Whatever weight there is to get to this point is fine, but it would be nice if from this point to release was a little lighter...and it seems that at this point you are really pushing against the striker spring. The sear has to push the striker back just a bit as the sear rotates down to get out of the way.

So I guess from the responses that there is a reduced power striker spring available ?
