    Works just fine in my Sig P229, no reason to believe it would be any different in an XDM. Ammo is pricey though...

    Just a description that made me laugh. Anyone who has shot both calibers knows exactly what I'm talking about. I'm not aware of anyone who trains with a 357 for their defensive 40...plenty go the other way around, however.

    Back to the OP-- 357sig is a fun round, and the conversion should be a piece of cake. But only invest in that barrel if you'd prefer the 357sig to the 40sw. I could understand wanting the 357 for defense, but practice/plinking with a 40 is just a whole lot less expensive.

    I understand where your coming from. 357 sig is to expensive to plink around with. I decided to go with a 9mm conversion kit. I'm getting the barrel from pistol gear and the guide rod and #16 spring from Springer Precision. I'm thinking I won't even notice my gun wasn't built to be a 9mm after these mods. Now 9mm on the other hand will be great for plinking. This mod will cost just under $200 shipped.

    By the way, is .357 sig better for personal protection over a .40?

    357sig and 40sw are pretty well in the same class as defensive rounds. A lot of people (and LE agencies) prefer the faster 135gr variety 40sw defense load, which is ballistically similar to the 357.

    I haven't been able to find any .40 135gr at any of my local stores. Is that a hard round to find?
