Sorry guys and gals, but I do have a stupid question. I have one holster coming from HighDesertLeather coming...an OWB that I ordered for my S9. Now, I will soon be the proud owner of an S40 also. Basically my question is will my new toy necessitate a new holster? I am seeing it is a 3.5mm difference in length between the two. However, I didn't know if the trigger guard, ejection port, etc., would be a factor. Is this a game changing difference? Sorry folks, I have been used to carrying OWB with a nylon Uncle Mikes so I'm basically brand new with formed holsters.
