Warranty on Glocks, Kahrs, and Springfields?

[Gun1]

Bought a Kahr CW45. Unknown to me, there was a few that had a problem with the front metal slide rails being too short. When I found out about it, I found I was one of the lucky ones. Contacted Kahr, gave them the serial number.
They sent me a mailing label to return the frame. Had a new frame and a new spare magazine in a week.

Did it have a different serial number? If so, did you have to go through an FFL?

Also, they can return your old gun directly to you from a repair, can they send you a new replacement gun or does it have to go through an FFL?

My experience.

Taurus sent directly back to my home after repair.
Glock sent a new gun to my FFL.

I sent it and received the new one through an FFL. Had a new serial number.
