I have a couple of the pearce grip +2/+3 round magazine extensions, and they say it is +2 rounds for .40cal, but there is absolutely no way I'm getting an extra 2 rounds in there. It seems to only extend capacity by one round. Not that its a big deal, but its something i have wondered about. I have tried this on 15 round g22 mags and on 9 round g27 mags with the same results. Any thoughts?

Pearce are +2 on 9mm .... +1 on 40

The PG39 says +3 for 9mm and +2 for .40 cal, I just looked it up on pearce grips' website.

"These units replace the magazine base plate and internal floor plate. They will add three rounds to the Glock M26, two rounds to the Glock M27 and M33 and one round to the Glock M39. These units will add 1" additional length for better control and comfort."

Is it just marketed wrong, because like I said, there is NO WAY?

My mistake, I was thinking of the PG2733. These have always been +1 on 40 and +2 on 9mm. You are correct, the PG39 holds 3/2/1
I should look this stuff up on my own web site, it says it there too.

Ok, why can't I so much as imagine putting 17 rounds in my G22 mag with this extension on it, or 11 rounds in my G27 mags??

Your G17 already holds 17 rds and the G26 holds 10 rds. If you installed the PG39 and cannot get another single round into the mag... remove it and reinstall. There is a problem for sure.

No, what I am saying is I have one on a 15 round factory glock 22 magazine, and can only fit 16 rounds into it, and I have one on a 9 round factory glock 27 magazine and can only fit 10 into that. According to how its advertised, I should be able to get 17 rounds of .40 into a glock 22 magazine and 11 rounds into a glock 27 magazine.

So, for my .40 caliber magazines, the pg39 has only proven to be a +1 extension
