I seem to get a lot of mixed information about +2 for my Glock 23. There are some certified Glock Armorers that say you just need the new plate. Another local guy says you have to get the plate and a new spring. Yet another local guy says you have to get all new mags.

Can anyone give me the scoop on +2s?

My plan was to buy them from Pearce and install them myself but with all the different informaton on them it is a little confusing.

Thanks

There have been lots of feeding problems associated with +2 base plates. They are generally caused by the spring after a +2 plate is put on. The spring has been made for a stock length mag. and by putting those on you are extending it causing less upward pressure. I would recommend using G22 springs in your G23 mag if you are using +2s.

There is NO need to buy new mags. The mag walls will last along time. The only thing that needs to be replaced on a stock mag from time to time are springs, and followers. Sometimes base plates if they hit the concrete too often. Hope this helped.

Here ya go pal, these are what I run on my G22 with 100% reliability. All you do is replace the factory base plate with these, no spring needed...One word of caution, these are the only ones that I recommend due to unsavory reports about most other extensions. Also I have yet to be able to get +2 in mine but Im sure it will happen sooner or later

Glock actually calls them "+" because they add 1 to .40 and two to 9mm. The insert and floorplate are exchanged. The spring can remain and I for one have had no problems with it. They do list a spring for the 17 and 34 when changing over to a 19 round capacity. (SP 02551) And I suppose you could dump the 10 coil into the 19 mag.

Now in the .40 that you asked about. (23 to be exact) You could change the spring from a 9 coil to a 10 coil, especially if using a light.

I have used "+" on my 27 with no spring change and no problems also ... do as you think is best.

While it don't look like you will get the same answer twice here either for the most part I will add this. This is a G23 mag with the + feature on it. I successfully fired two shots out of the pistol. The one in the barrel and the next round that was in the mag. The rest I dumped out into my hand. This was a mag I never had problems with and never had problems with again when I removed the + feature.

What I think was happening is this...Under recoil of the gun the insert got caught in the floor plate. The spring didn't have enough upward pressure to correct the problem causing this "mess". Think of it like this... People replace springs all the time because they get weak. You have already weakened that spring by lengthening the area it is supposed to operate in.

For example take a spring that is made to maintain upward pressure in a area say for example 6 inches long. Take the same spring and put it in a area 7 inches long and it will not have the tension it is supposed to have and is now weak. Here is a pic showing what happened to mine.


You are looking down inside the mag the follower is on the bottom of the mag. The spring is still in it. It didn't have the umph to correct itself. I would recommend in addition to G22 springs also look at the +10% springs made by wolf. Here is a link to them. I use them to make sure something like that pic never happens to me in a time that would be real bad.
