One of the few complaints I have about my 'baby' Glock, is the short hand grip. If you have medium to large hands, it feels somewhat uncomfortable to hold because your pinky is off the grip. Even adding a plus 1 or plus 2 with a pinky extender never felt fully comfortable to me. I found this A&G grip extender at a gun show today,and it seems to be just the ticket for getting a good grip on the pistol. The key here is to use a mag from a larger model pistol. In my case, I used a G-23 mag which, being the same caliber, fits my G-27. This should work on any of the sub compact Glocks, as long as you use a mag from a larger model of the same caliber. The extender is made by A&G, and costs about $13. It attaches by sliding it down over the mag, inserting the mag, then tightening a set screw on the back of the extender. It adds almost an inch to the hand grip. I have medium size hands, and for the first time, the grip is truly comfortable. Even large handed people should notice a great improvement. One thing I noticed, is that I really had to pop the mag into place to get it to seat properly. I solved this by sanding a little off the areas where it butts up against the mag well. I imagine many of you already knew about this item, but I just discovered it today, and I am VERY pleased now that I am able to have a firm grip on my pistol.
