He did not say it was for SD, he said he was looking for a starter firearm.
He can get another size for SD or HD later on, after he has training. And he may not want a .40. I don't like .40, does that mean you should not like it? No, it doesn't.
My mistake. I thought he used the words "self defense repertoire". I'll go back and check. Maybe you should too.
As far as me suggesting a .40, it was just a suggestion. I'm not here to force him (or you) to like it.
I started years ago with a 9mm. I didn't find it to be difficult, even as a beginner starting out with firearms.
