CraigH, welcome to the campfire. You can order scopes from Leupold's custom shop is the scope is not a standard over the counter scope. You can order a 3x9x40 with the #4 or any other Leupold scope with the #4. You save some on shipping since you don't pay for the shipping to the custom shop and the scope is built for you. I have done this several times for non-standard reticles. .
Yes Sir,good info. I would only add that not all #4's are equal. That even holds true sometimes in different models from the same manufacturer. My favorite of all time is the Mepro #4 that was in their discontinued 3-9X42. That particular #4 had very heavy bars that came very close to a fine center. It was such that IMHO it gave the best of both worlds, a fine center for precision but heavy posts close enough to bracket a deer's vitals easily in low light, even if you couldn't see the fine center.
