Glock 22 Springs

If you make no other changes, replace the recoil spring and trigger spring

Spring Time:

The .40 S&W cartridge is tough on pistol parts, it always has been and the item that wears out the fastest in a .40 caliber pistol is the recoil spring. This is also where opinions will vary. If you ask three gun makers for the recommend round number to replace a recoil spring, you will get three different answers. I have been told 2,000, 5,000 and even 10,000 rounds is the limit for a recoil spring. The official round count from my good friend at Glock is 3000-5000 rounds.

If you purchase a Police Trade-In Glock 22 or Glock 23 pistol, you are going to have no idea how many rounds were put through that gun or if the recoil spring was ever replaced. It is true that many police guns are carried a lot and shot a little, you might have the pistol of that one cop who loved to shoot.

If you do nothing else with your newly purchased trade-in G22, replace the recoil spring. Lone Wolf Distributors has numerous styles from which to choose. Of course, you should figure out which generation you have, there are slight variances. Most likely your trade-in pistol will be a Gen 2 or 3. If you are stumped, contact Glock, Inc. directly.

The trigger spring is the next place I would focus. A Glock trigger spring is ridiculously easy to replace and costs next to nothing. My personal G23 had a broken trigger spring about ten years after I started carrying it. As I put this piece together, Brownells has Glock triggers springs listed at $1.99. Don’t be a cheap ass, replace that spring.

Additional Parts:

If the recoil spring on your trade-in G22 was swapped out regularly by the department’s armorer, then the internal components should be alright. However, as you have no way of knowing that, there may very likely be stress fractures already forming in certain parts that absorb the shock from each round fired. Yes, the parts might look fine to the naked eye. Unless you can x-ray them, I would just replace the pieces.

The locking block and the associated pins are the prime culprits for stress fractures and broken parts in a .40S&W Glock pistol. This is not a Glock issue, this a .40S&W issue. The Smith&Wesson 4006 pistols had innumerable problems during their lifetime. A replacement locking block for a G22 should be around $30 or less and is good insurance for a pistol refurb project. Naturally, the associated pins should be replaced for good measure. Again, they are less than $5. The slide lock is another part that can be replaced easily and inexpensively.

If your trade-in pistol did not come with manual, okay I know it did not come with a manual, you can find Glock manuals and schematics online. Brownells has a Glock pistol schematic on their website. If you trouble with any of the parts you purchase from Brownells, you can always contact one of their onsite gunsmiths for assistance.

Also, before I let you go, stripping down your police trade-in gun to swap/inspect parts is a great time to clean out the five to ten years of carbon, dirt, and funk that has built up inside. Bust out the Froglube solvent and “Extreme” CLP and that used gun will be running like a champ in no time.
