Just picked up a Glock Model 40 MOS (10mm). For training purposes I would also like to be able to shoot .40 S&W with it. While this arguable can be done with no changes whatsoever, I would prefer a dedicated .40 S&W barrel for it. Does anybody know if the Glock Model 24 (.40 S&W) barrel will drop right into a G40? While they are the same length, I cannot find any info on dimensions of the hood (like width) or whether there are other differences (lug or ramp) between the two. I realized there are aftermarket conversion available to do this from KKM and LW. Any others to consider (that don't require a file/gunsmith)?
