Now I'm no expert but I do believe it's the same size as the 26/27.nice, how does the 33 compare in size to the 26/27
Two other mags, that came with the gun, have Pearce extensions on them. Definitely feels alot better with the extensions.Congratulations on the new Glock. I love my G33. I added the Pearce grip extensions for all my G33 mags.
