I’ve been shooting my XDm in USPSA Limited category and have been wanting to add these updates for a while now. You know that the .40 S&W is snappy and very stout and one of the ways to help is to increase the weight up front. I did that by getting a Tungsten Guide Rod from Canyon Creek. I also got the Tungsten Magazine release to help with the weight & reaching the mag release button without changing the grip.
The guide rod protrudes a little but doesn’t change the overall length of the gun.
