There is nothing to hold this product in the grip frame. I installed mine and drilled a tiny hole where the hole in the lower rear of the grip frame already exists through the frame plug. Took a short black self tapping screw and snugged it up. You could also drill the plug and tap it for a headless set screw like most of the mag wells come with but either way the plug will not fall out now and the screw looks just like any other gun with a mag well or a slug plug installed.

I purchased this slug plug for my Gen-3 Glock 21 (45ACP). When inserted into the handle, it fits flush and looks great. Unfortunately, its only held in place by friction. Thus, after the 1st shot on the range it fell out onto the floor. I re-inserted the slug plug by inserting more pressure and again it fell out. I guess I could glue it in place, but am not currently prepared to make that permanent adhesion to my Glock.. Based upon this, I would NOT recommend this product.

This one fits a little tighter than the last one I had. The one that fell out at the range somewhere when I was shooting last time. It does look better than just having the hole there. Makes it look more finished looking. Think maybe this one might stay in a little better. We'll see when I go to the range next time. I was thinking if it did fall out again, maybe a little Loctite on certain places around the plug or inside the well will help it stay in there better.

Overall the insert is good and for the price I will be using it. My only concern is that this model does not have any type of built in retention. It relies on friction only. It has worked loose from carry alone. I haven't fired the gun with it installed but I'm fairly certain it would work free under the recoil of the model 20.

Yeah, first day at the range with the Glock 20 and this special 'plug'. Yeah, huge plus one the cosmetics, but the dang thing fell out after just firing the 10mm round just once. And these are the easy going rounds, like only 1,100 feet/sec. I don't like using loctite or glue, but appears I must or keep losing these things at the firing range.
