Quoted:
A couple of months ago I was ordering some small parts from Dillon and notice the Korean G22 mags for $15.95 each so I added two to my order.
The mags (of course) were BO'd and finally showed up yesterday.

My G22 is a older pre finger groove model and all the other mags I have (Glock factory 10 & 14 rd, & 2 Scherer's) fit and function fine.
The 2 korean mags are very snug going in and a hard pull to remove.
By the marks on the back of the mag sides it looks like this is the area that is binding.
got out my calipers and measured a sampling of my mags and these are the results:

Glock 10 rd:
front to back width: 1.306"
side to side thickness:.915"

Glock 14 rd:
front to back width: 1.312"
side to side thickness:.910"

Glock 14 rd LEO:
front to back width: 1.308"
side to side thickness:.910"

Scherer 29 rd:
front to back width: 1.308"
side to side thickness:.895"

Korean 14 rd:
front to back width: 1.315"
side to side thickness:.924"

The Korean mags are marginally larger in both dimensions.

So now I'm wondering, do older G22's(or at least mine) have a slightly narrower mag well or are these Korean mags actually out of spec 2nd's.

Thoughts???
