Bought a XDM 4.5 in 45 acp a couple of weeks ago, have put 500 rounds through it as of today.
I am an avid shooter and reloader (mostly 1911s) for the last 20yrs or so, I have stuck with a light target load that is mild and ACCURATE.
The XDM would NOT run with the stock spring, so I put a 14# spring in, now, this gun is far better a shooter than I had hoped, in every way.
Yet another plus, NO trace of leading.
I got this pistol just to have a non-1911, couldn`t be happier with the choice. :eek:

How much less is a #14 spring than the stock supplied spring?

Can you still reliably fire normal and plus ammo with that lighter spring?

Thanks

I believe the lighter spring is for lighter loads. The lighter the load the less rearward force acting on the spring. So if you run a super light load on a factory 18# spring you will get failures to eject and other cycling issues. If you run a +p ammo on a 14# spring you will cause excess wear on your pistol. Someone can correct me if I'm off

^^^ that.
If I were to shoot factory/ hardball loads, I just drop-in the 18# spring. My 4.5 XDM is a range gun and those light loads are just too much fun.
