Can we call the new line the SD gen 2? Which means they are no longer producing gen 1. Would that characterization satisfy everyone?
If someone asked me if the "new" SD's were the same as the "old" SD's, I'd say yes except for the finish and sights. And they make small changes on all the time on different models. Take a look at all of the dashes on the different revolvers. Did they discontinue one model and introduce another model just because the new ones aren't pinned and recessed?
I do agree with MLK18 that really it's all semantics. In the end, does it matter?
