As you probably know, I recently picked up a Gen4 Glock 19 as a new concealed carry pistol. I wanted to go back to a doublestack gun, and I also wanted something that was very similar to my Glock 34 that I shoot in competition. I don’t tend to make a lot of modifications to my carry pistols, but I’ve done a couple things to the Glock 19:
Custom Grip Plug Funnel
Glock pistols have a giant gaping hole at the back of the grip. This isn’t a big deal until you start dry firing the pistol regularly, and then quickly find out that the case rim of the top round on a magazine can get caught on the piece of plastic that divides the magazine well and the hollow area at the back of the grip. A lot of folks will run a standard grip plug from any number of manufacturers to fill the gap and resolve the reload problem. I couldn’t leave well enough alone, and after looking at the grip plug, I decided that I could make it better.
I took the standard Pearce grip plug that my local gunshop has for just a couple bucks, filled it with fiberglass resin to give it some extra strength, and then carefully sanded it into a funnel shape with the sanding drum on my Dremel. What I ended up with was a grip plug that not only keeps the magazine from hanging up while reloading, but it also makes a (marginally) bigger target for the incoming magazine to hit when reloading the pistol. I’ve since done this same modification to my Glock 34 competition pistol as well.
I’m a real cheap SOB these days. After buying this Glock 19 I tried modifying the awful plastic factory sights by taking a set of jewelers files and very carefully filing the notch in the plastic rear sight deeper, and a little wider for a better sight picture. I then took a black paint pen to the rear sight and blacked out the big, distracting, white U shape that Glock puts on their sights. This improved the sights a bit, but they were still pretty awful.
I’d been considering adding a set of Sevigny sights to this pistol for continuity with my competition gun, but I’d forgotten that while they are great sights, they come at a premium price (currently with shipping, about $85 for a steel rear sight, and F/O front). After looking around at similar options, I found some acceptable sights from Ameriglo that give me a very similar sight picture for $50 shipped (GFB-103).
These sights are pretty simple, black rear with a square notch, and a red fiber optic front sight.
The Ameriglo rear sight moves the face of the rear sight all the way to the back of the slide which maximizes the sight radius, and it has a nice ledge on the opposite end that can be used to one handed slide manipulation, if you care about that.
Those are the only two modifications I’ve made to this pistol, and they’re probably the only mods I’ll be making to it. The trigger is good enough, the sights are pretty good, and the ridge inside the magwell can’t catch my magazines anymore when reloading the pistol. Good enough.
