I’m often asked what I do to my carry pistols once I purchase them. I don’t think I have a pistol in the safe that I haven’t modified. The last pistol I picked up was a Glock 17 Gen 4. What I do to most of the Glocks I have is as follows:
1. Polish the feed ramp: Taking a Dremel Moto Tool with the correct polishing bit ground down to about 10mm works best. I polish the feed ramp and the bottom of the rear of the chamber. When the ramp looks like a mirror I call it done. Keep in mind that doing this removes the factory finish so if you’re one of the people who cleans your pistol once ever ten years there might be some rust on the feed ramp. Polishing the feed ramp allows the rounds to feed a lot smoother. You can feel the difference when feeding the round. It seems to just pop into the chamber with very little effort.
2. Change the sights out: The factory night sights are bright and I like them, but I have found that the Tru-Glo TFO sights are extremely visible both day and night. When putting in the front sight, I put a drop of Loctite on there to keep the screw from ever coming loose. When the rear sight goes on I center it on the slide. The factory set screw that comes with the sight is always too tall. I take off some material so that when the screw is tight it’s not noticeable when looking down the sights. I then Loctite the rear sight set screw AFTER I take the pistol to the range and ensure that my point of aim is the point of impact.
3. Change out some of the factory springs: I’ll change out the firing pin spring and the plunger spring with lighter Wolf springs. I don’t put in the Wolf trigger spring simply because I have had 3 of them break on me in the past 5 years. The stock Glock spring has never let me down.
4. Stipple the grip: I take a soldering iron and go to town on the grip, producing hundreds of small dimples around the circumference of the grip. Once this is done, you could cover your hands in oil and still have a solid grip on the pistol.
5. Clean the face of the trigger: If you have a Glock you know that the safety on the trigger doesn’t sit flush with the trigger itself. Not a problem for your weekend plinker but if you’re sending 600 rounds down range every day for a week that one contact point can leave your trigger finger with a blister. I take a curved file and depress the safety, then file off the high spots. I don’t file off the top portion of the protruding safety, doing so would allow the safety to travel to far forward and thus making it stick out and prone to snagging on things. Once I’m content with the feel of the trigger face I polish it smooth.
6. Polish contact surfaces: I’ll mirror polish the trigger bar where it contacts the plunger, and also where it contacts the Disconnector. Then I’ll polish the striker where it contacts the trigger bar.
7. Install a Ghost Inc. 3.5lb Disconnector: No mods here
8. The last thing I’ll do is clean out the trigger guard. I have large hands so the edges of the trigger guard tend to wear your skin down (AGAIN Not a problem for your weekend plinker but if you’re sending 600 rounds down range every day for a week, different story).
People who have shot my Glocks are amazed with the trigger. Most of the reset’s feel almost like a 1911…. almost! KEEP IN MIND THAT ANY MODIFICATIONS TO THE FACTORY PISTOL ARE DONE AT YOUR OWN RISK
