My forum search skills are weak! I recently bought a P220 .45ACP in the G142xxx serial range with the front sight as an integral part of the slide. When did the P220 move to a dovetail front sight? (Date code or serial number range.)

The first dovetailed P220 front sight was observed ~1992 in the G 188,xxx serial number range (KC proof code).

Thanks!

I have an eighty something P220 that had the same original sights. I had the slide cut for dovetails. Now I have sights that I can see!
