It appears to be a no dash. 1 (possible issue) with using certain magnum ammo binding. Hammer nose bushing I believe. That being said, Smith will fix it for free. (recall) I have a 4" blue no dash myself. I did not send it back. For what I shoot will NEVER have a problem. You can search threads on this.
If functions well, price is very GOOD! Let us know how you make out! Bob
