10mm is 10x25mmDoubleJ wrote:so, an XD40 can shoot a 357Sig round, but with a different barrel.
can you then get a 10mm Barrel & Mag and shoot 10mm with it?
would this be the equivelent of shooting +P rounds of 40SW?
oy....
.40S&W is 10x22mm
I don't think 10mm would fit in the XD40 magazine but I guess you could try.
