Most Helpful Positive Review Better grip to control a 10mm
The OEM base plate on my Glock 29 mag was a little tough to slide off at first. You have to coordinate squeezing the sides of the mag nearest the base plate while sliding it off which can be difficult. The only problem I found with the Pearce mag extension is the plastic piece that catches the magaz...

Most Helpful Negative Review Pearce grip for 10mm
It did have a good fit and it seems to work so far I haven’t shot with it yet. Although The base plate with comes with was hard to get on and the little bump in bottom of the plate was hard to get to match up with the hole on the extension. Also I Just don’t get how it’s brand new but came with wear...

Great Purchase

by ParatrooperVeteran, from MI, United States Written on February 6, 2026
My hands are big my G29 SF was uncomfortable to grip with my pinky finger hanging off but this made my gun way better, didn’t really care about the extra 2 rounds but I can verify it does hold 2 extra rounds. It took a few minutes to figure out how to take off baseplate, I took a small Phillips head and pushed spring down through hole on bottom about 2” and baseplate slid off easily. Putting extension on was a little tricky putting aluminum bracket over spring and pushing it flush with mag then sliding extension over it but everything lined up button slid into hole without any problem. I ordered 2 of these my G20-5 mags wobble and don’t seat good enough to comfortably use so I recommend this product just be patient and do it correctly btw it was my first time doing a mag extension or changing baseplates.
Pros:
  • Great for big hands
Cons:
  • None
Best Used for:
  • Big hands
Would recommend: Yes

Solid product. They are +2 extensions

by Big Herm, Verified Owner from NH, United States Written on November 14, 2025
The item description doesn't tell you, but they are +2 extensions. Pearce says that you'll need to run around 250 rounds to 'break them in' if you are having feed issues right away. Absolutely make handling the Glock 29 recoil with full loads easier!!
Pros:
  • Comfortable
  • Good fit
Cons:
  • None
Would recommend: Yes

Feel firm but do do not function as described

by Aj, from WV, United States Written on February 17, 2024
After installing these on my oem Glock mags for my Glock 21 they do not add +2 I was barely able to force an extra round in my magazines I don’t see how 2 would be possible, I’d check other options

Fitting the Grip

by GryMn, from ID, United States Written on October 8, 2023
I have these on a few of my Mags. They help with gun control by providing a place for your little finger. I do file the front of the extension a bit, because they can be uncomfortable while shooting. A compact 10mm has a bit of recoil.
Pros:
  • Great fo control
Cons:
  • Challenging to remove
Best Used for:
  • Large hands, short frames
Would recommend: Yes

SOLID 9.5/10

by Phill N. Coffins, Verified Owner from NV, United States Written on July 21, 2023
Perfect to fit my pinky on there when shooting. Definitely difficult to remove the original base plate but I made it happen. Only reason I give it a 9.5 is because the mag is a little rattley. Shoots perfect grips perfect.
