Along the lines of the previous post, can you install a Model 4006 .40 S&W slide and barrel assembly on a model 5906 9mm frame and have it function properly? I would imagine you need a .40 magazine as well. I emailed S&W with this question but they did not reply. I have a Model 5906 that is not very accurate and figured I might be able to turn it into a .40 S & W. Thanks for the help.
