Heavier striker spring info?

[lowk_18]

Hi guys,

I've been thinking about picking up a heavier striker spring for my XD9. The reason for this is that I've had a few FTF's. The rounds always fired on a second strike. I'm fairly sure that this is due to hard primers as it was almost exclusively with BVAC ammo.

I know that most will reply "Use ammo that works in your gun". My reply to that is that I would like my pistol to work regardless of what I put in it.

I've been reading about it and it sounds like I need a heavier recoil spring if I put in a heavier striker spring to balance it out. It also sounds like a heavier striker spring makes for a heavier trigger pull but I don't know to what extent. A little heavier trigger pull wouldn't bother me.

Is there a rule of thumb (such as if you increase striker spring by 1lb then increase recoil spring by 2lb) or is it just trial and error?

I know that I'm chasing perfection here with a gun that's been extremely reliable but if I can eliminate the FTF's altogether without sacrificing any reliability, that would be great.

Any input is appreciated.

lowk,

I'll keep things simple and say for the XD platform, you DO NOT NEED to increase the recoil spring force. The gun doesnt work like Glocks or M&P's. On the XD series, the striker is fully loaded/sprung when you cock the gun. If you put in a heavier striker spring, it will increase the trigger pull. It may also make any rough spots in your trigger more 'pronounced'. Do NOT put in a heavier recoil spring. You may start to experience failure to feed or ejection issues. Stock is generally the most reliable version.

As for BVAC ammo, Ive never heard of them and im always a bit hesitant about the Q/A with reloading companies. I know you want your gun to run 100%, but if they're not producing reliable ammo, no amount of modification to your XD is goign to make it go "bang" every time.. It's like any equation, you remove as many variables as you can and then go from there.. IMO, your selection of ammo is most likely the culprit..

Thanks a lot, Voo!

I didn't know whether the heavier spring would be a "it couldn't hurt" thing or not. As you've indicated, it clearly CAN hurt so I'll leave the gun as it is.

The heavy striker spring will increase trigger pull, increase wear on the disconnector, and increases the risk of piercing the primer. Best bet, try different ammo, the xd spring handles NATO primers, it should handle any commercial ammo. Sounds like primers may not be fully seated or have been desensitized.
