Most Helpful Positive Review For a RIA BBR 3.10
This grip extension works if you have a little skill and are willing to do some work. Instead of going with the hole in the bottom for the spring endplate, they put a clip on the back of the magazine. This hits the back of the frame when putting in the BBR pistol and dislodges the extension, fubaring it. To remedy, I cut the clip off flush with a dremel and drilled a hole in the bottom to match the spring endplate. Works like a charm now.

RIA BBR 3.10

by Az man, from AZ, United States Written on June 14, 2024
Bought this for a Rock Island bbr 310. The extension fits the magazine. Just fine, but when you put the magazine into the gun, the back clip securing The floor plate gets disengaged by the frame of the gun. To fix this, I drilled a hole in the extension in the same place as the original design Cut off the back clip with the dremmel. Then it worked just fine. If ur Not ready to do some work. Do not buy this for the Rock Island BBR

Too thick for P12 mags.

by Trey, Verified Owner from AZ, United States Written on September 12, 2022
Baseplates are too thick to permit the magazine to seat properly and for the magazine to catch. They wouldn't work on three different Para-Ordnance P12 factory mags, either with or without the grips installed (tried this because I thought that the rubber Hogue grips might be the issue. They weren't.) It's too bad, I really wanted it to work.
Pros:
  • Look great and seem to be sturdy.
Cons:
  • None
Would recommend: No
