i just picked up a 23 and wouldnt mind adding 1 or 2 to the capacity. i have a 27 with one installed(dont know what brand)but it has a big +2 on the bottom of it. anyways just wondering what the consencious is on these things and if one brand may be better that another. are they just a +1 for the .40? cant remember how many my 27 will now hold.

also is there anyone HERE selling them TIA.

For the 13rd G23 mag I would get the factory +2 and not mess with the others. Or for a spare you could get a G22 15rd mag.  

not a bad idea on the G22 mag, never even crossed my mind. where can i find the factory glock extentions?

you do know it is a illegal to import or build a magazine over 10 rounds in california right?
