So I added some Magazine Extensions on my glock 27 mags. Here is the problem I am having. With the two new magazines that came with the gun there is about a 1/8 of an in gap to where its not "flushed", but with the two used mags I bought at a gun show its fits like it should no gap or anything. Can someone help me out here and tell me why this is.
I have a 21sf & a 27. I see that space between the base plate and the grip in both guns. My wife won't shoot the 27 because she says the gap pinches her little finger. I use the Pearce +1 extension on the 27 when I shoot it as a 40s&w or 357sig. I use the Glock factory extended mags when I convert it to 9mm. I like the feel of the Glock extension better but it sticks out more when CCing. My wife says that it doesn't make any difference. They all pinch her pinky. Oh well, I guess she will stick with her Buck Mark.
Someone else might come along in a minute that can answer this question but is an insert required? I believe some floor plates and/or extensions require one. There is even a GLOCK part listed on the parts order form. I have always been fuzzy on this myself but don't use + ext on my sub-compact mags so it hasn't been an issue.
