Glock pins are small parts that do big work, and the Cross Armory CRG4PSSV 4-Pin Set gives your Gen4 a proper upgrade over the factory hardware. Each pin is precision machined, not cast, from 4140 ordnance steel, then surface treated for a clean silver look and better corrosion resistance. It is a straightforward drop-in swap for the stock pins, so anyone comfortable working on their own frame can knock it out at the bench in a few minutes.
The pins in your frame hold together the pieces that make the gun run, including the trigger assembly, the locking block, and the ejector housing. Factory Glock pins get the job done, but going with machined 4140 steel means tighter tolerances and a part built to resist creeping out under recoil. The silver finish is also a nice touch if you are building out a two-tone pistol or just want the internals to match the rest of your setup.
This kit is designed specifically for Gen4 models and includes an extended backstrap pin to work with the Gen4 backstrap system, which is exactly where a lot of generic pin sets fall short. It covers the common 9mm, .40 S&W, and .357 SIG frame sizes like the 17, 19, 22, 23, 26, 27, 34, and 35. It is not made for the slimline guns such as the 42, 43, 43X, and 48, since those use a different pin layout, and the wider trigger pin on 10mm and .45 ACP frames means those aren't a match either. Check your model before ordering and you will be set.
If you have swapped a connector or done any trigger work, fresh pins are cheap insurance against the wandering pin headache that plagues a lot of DIY builds. This is one of those quiet little upgrades that pays off every time you break the gun down and put it back together.
It is built for Gen4 frames in the standard calibers, covering popular models like the Glock 17, 19, 22, 23, 26, 27, 34, and 35. It does not fit the slimline guns such as the 42, 43, 43X, and 48, and it is not intended for 10mm or .45 ACP frames since those use a wider trigger pin. Always confirm your exact model before ordering.
A standard Gen4 frame runs three pins for the locking block, trigger, and trigger housing. Cross Armory includes an extra extended backstrap pin so the kit works cleanly with the Gen4 backstrap system, which is why it comes as a four-pin set. You use the pins that match your frame configuration.
It is a direct replacement for your factory pins, so most owners can install it at home with a proper punch. A good habit is to remove the upper locking block pin first, then the trigger pin, then the rear housing pin, and reinstall in the same order and direction. If you are not comfortable working inside the frame, any gunsmith can handle it quickly.
These pins are precision machined rather than cast from 4140 ordnance steel, which means tighter tolerances and solid strength for a part that takes constant stress. The surface treatment adds corrosion resistance and gives the silver finish, so they hold up well and look good doing it. It is a durable, good-looking alternative to stock hardware.
