A few days ago, I ordered some Lone Wolf plugs for the gaps behind the magazines in my Glock 17 and my Glock 26. They arrived today, so I put them in and I think they look really good. Hopefully, these will keep some of the dust and lint out when I'm carrying. Here is the one for the Glock 17. And here is the one for the Glock 26. The one for the Glock 26 actually got some bad reviews because it does not lock in place. (Because there is no hole in the backstrap to lock into.) Has anyone here had experience with this plug. If so, have you had any problems with it coming out? Either way, for $6.95, I decided it was worth a try.
