I bought a Storm Lake .357 Sig conversion barrel for my XDM 40 and it is a great barrel. Just about every load I've tried has been a winner, 2 to 2-1/2 groups at 25yrd are easy, less if I can do my part. Fit was perfect,I'm a machinist so I used my mics and compared to factory and found in many areas the Storm Lake barrel was tighter fitting than the factory. I can go to the range with one gun and in 1 min I can switch between 2 calibers.With the 357 Sig nothing has to be changed to the gun,with the 9mm barrel you have to change the recoil spring,9mm mags,and sometimes the ejector.
For around $150 you can "have a different gun",great deal!!
