Frequently Asked Questions

Lead time information is kept up to date towards the bottom of our home page, in bold. We ask that you do not request status updates unless you are within at least a few days of the full lead time. We will always strive to meet them but lead times are given as approximations only. We are a rather small enterprise and intend to stay that way; quality over quantity. 

Cards are charged within 72 hours of an order being placed. Why? Payment information cannot be held securely for these lengthier lead times.

Should you decide you cannot wait out the lead time after ordering; email us for a cancellation/refund as soon as possible. We do not currently charge a cancellation fee. Email for changes/cancelations: [email protected] 

All orders are shipped via USPS Priority 3day Mail.  If  necessary, you can email us to request FedEx – or – place this information in the “optional note” section on the Checkout screen before completing your order.  We read every notation.

~As of September 2023, unfortunately, FedEx upped their rates and now charges about $26 for their best rate, so we will require additional payment if you prefer them over USPS. We will look up the cost and call you for payment of the difference when you order is getting ready to ship. 

~UPS and other couriers are not an option.

 

Our standard twist rate is 1:16 for ALL makes and models. It is the only twist rate we offer for Glock and M&P. 

If you are looking for a different barrel model, we have options from 1:10 – 1:34. Just tell us your preferred twist rate in the optional note section of the Checkout screen. There is no extra charge and we read every note prior to production. 

Button rifling is a far more expensive and time consuming process then broached/cut rifling, but the gains in accuracy are far greater with button rifling. Our extensive knowledge of precision long range bench rest shooting has taught us that the bore has to be dimensionally perfect from the chamber to the muzzle to shoot at distances greater than 1000 yards. In a rifle barrel the bullet has time to stabilize in the bore but in a 5inch pistol barrel there is very little time for this to happen. That’s why a pistol barrel bore must be dimensionally perfect both in size, roundness and surface finish from one end to the other. Only button rifling can achieve this level of accuracy. Our National Match barrels routinely shoot sub one-inch groups at 50 yards.

Our drop-in barrels are meant for factory slides and frames and should drop right in without any other alterations required.

We do add extra material to obtain a better lockup for increased accuracy so in some cases light fitting may be required but is extremely rare. In this situation, reach out to us by email and we will find a solution.  Email: [email protected]

The compensator is first threaded onto your barrel.   The barrel’s threads have milled flat spots on each side where the set screws engage, to keep it locked down in place. We provide two set screws and a wrench to screw into each side of the compensator, on these flat spots.  Be sure to pull your slide back and thread it on all the way prior to engaging the screws. If you do not thread the compensator on fully, you can ruin your threads, making it nearly impossible to get the comp off. THIS HAPPENS RATHER OFTEN so be careful and always contact us if you have questions or concerns. If you destroy your threads, you are potentially looking at the cost of a new barrel.

If you decide to use Loctite, go for blue and be sure to keep it off of your barrel threads.

The set screws for the compensator are 8-32 x 1/4″ cup point in grade 8 steel.

Sure. We keep an inventory of uncut barrels so we can customize the length to a customers needs. There are maximum lengths for each though and nothing is able to be longer than 7.25″.   

In the optional note section of the Checkout screen, just tell us the overall length (OAL) you are looking for. We do not charge extra for a custom length.

The majority of our customers choose aftermarket barrels largely to run hotter ammo through their guns.  

Regardless of demand, out of safety consciousness, we have decided not to add the 10mm M&P options to our production list. 

Unfortunately, no. We don’t have the correct tooling or programming to do either of these. Currently, there are no plans to make these in the future.

No:  With the exception of the recently released Gen 5 pistols. 

If you have a Gen 1-4 gun, any barrel not labeled as Gen-5 will work with your pistol. 

At this time, the G17, G19, G20, G22, G23, G26, G27, G34 are able to be produced in Gen 5 specs. 

If they are not listed on the website, we do not have them available to order yet. 

Right now, the G17, G19, G20, G21, G22, G23, G26, G27 and G34 are the models with Gen 5 options. 

Yes. Once the barrel is fit to your slide just send us the barrel and we will finish chamber it for you and send it back.  We can finish chamber all of our gunsmith-fit barrels. The cost is $15 plus shipping charges. Please allow for extended lead times on all finishing work.

We use SAAMI Spec chambers in all of our barrels. Good quality reloads will work fine in our chambers. The reloads must adhere to SAAMI Spec dimensions otherwise, we cannot guarantee fit and function. Ammo outside of these specs will void your warranty. 

If a customer has a special reload that they want the chamber cut to, we have an inventory of chambering reamers for custom jobs. Just send us a few rounds of your reloads and we will custom tailor the chamber to fit.  The cost is $15 plus shipping. Please allow for extended lead times on all custom work.

No. We do not recommend shooting 45 Super out of any Glock or M&P, regardless of the barrel. The guns themselves are not safe enough, in our opinion, to handle these hotter loads. Using 45 Super with our barrel will void any warranty with us. 

Yes, +p is absolutely safe to shoot; however, +p+ is not and will void the manufacturer warranty.
