in 69xx or x69 series compacts, Marlin Camp 9 carbines, early KelTec Sub 2000 folding carbines set up for S&W magazines, and KelTec P-11 pistols. Also the Daewoo 51. Probably others.

I'd LOVE to hear about any others.

This is why MecGar still makes 15 and 17rd (flush fit) and 20 rd S&W mags.

For the record, there is a gun shop, in Kentucky I think, that has made special extended base plates so they have frankengrafted a KelTec P-11 12 rd mag to this special base, so it is a flush fit 69xx magazine.

Old S&W 14rd mags can take the late model 15 rd followers to make them 15 rd. I think 69xx followers will do it to.
