Why should I modify my handgun?

There are many technical answers to this question, but the simplest reason we can offer is this: "To be different!" Glock pistols are the most prolific handguns in the world, and they all look the same. Don't settle for being one-of-millions when you can be one-of-a-kind.

Of course, there are inevitably those among us who simply don't care about how their gun looks, as long as it performs the task required of it. We welcome you as well! Our modifications can substantially elevate your handguns performance, whether it be the utilitarian addition of an optical sight and simple forward cocking serrations, or a full blown milling package, we guarantee you'll be pleased with the result. If you aren't for any reason we'll work with you to find a solution. Oh, and your gun's going to look damn good, too!


How do I ship my items for customization?

Please see our Shipping page for complete directions if you will be shipping your slide yourself. Or consider using our Valet Slide Service!


What is the "Return Shipping Signature/Insurance" option?

Effective for all orders #9001 and over.

This option allows the customer to choose their desired level of liability protection during return shipping.

The $500, $1000, $1500, and $2000 insurance options indicate our company's maximum liability for the replacement value of your components. For example: If you select the $1000 insurance option and your slide/parts/optic/etc is deemed lost or irreparably damaged during transit after leaving our facility, Maple Leaf Firearms LLC will furnish an equivalent replacement of up to $1000 at our dealer cost as quickly as reasonably possible, subject to the availability of components.

This protection does not carry any "cash" value. In the case of loss or damage, Maple Leaf Firearms will provide compensation in the form of equivalent components only, and under no circumstances provide cash compensation for the lost parts.


How do I check the status of my order?

After you place your order you will be able to view your current order status by logging into your customer account.

Once you send your parts and they are received here, we will inventory them into our system and mark your order as "Received/In Process". Please allow a few business days from the time your parts arrive here for us to get them unboxed and inventoried. You will receive an email when your order is updated to "Received/In Process".

If we find any issues with your order once it is inventoried it into our system, we will contact you directly at that time.

The next update you will receive from us is when the work is completed and we are shipping your order back to you. You will receive a tracking number via email when your order ships.

In an effort to keep lead times as low as possible for all customers, it is our company policy to not issue more detailed status updates.


How do I make changes to my existing order?

Please ensure your order is entirely correct and contains all features you would like on your custom slide prior to finalizing and placing your online order. Due to the streamlined nature of our machining process and workflow, it is extremely time consuming and inefficient for our staff to make manual order changes to existing orders once they are in process.

If you do wish to make a change to an existing order (such as a change in optic cut configuration, or change in milling design, etc) once your online order has been placed, you will need to complete our Change Order request which can be found on the Order Changes page.

As of 12/6/2020 this is the only way to make changes to an existing order.

Please note that while we will make every reasonable effort to accommodate change order requests, we cannot guarantee the requested change will be possible to make. If we cannot accommodate your requested changes we will refund the Change Order fee and your order will be processed in the configuration as originally ordered.

Please note that some changes may incur an added fee for the additional work performed (ie change in design from a $200 package to a $300 package). In such cases the customer will be invoiced separately for the remaining balance. The fee for the change order request does not count towards any additional balance on the order.

If you wish to add products such as a set of iron sights to an existing order, please place a new order for the items and leave a note in the order comments with your current order number, requesting them to be to installed and returned with your existing order.


Can you work on other models that are not listed on your website?

No. If the make/model is not listed on our website, we do not work on it.

At this time, we ONLY work on most Glock, most S&W M&P, Sig P320, Sig P365, and HK VP9 models.


What is Valet Slide Service?

We will resume this service as soon as possible when an alternative shipping method becomes viable. Inbound Valet Packages will still maintain our Valet guarantee of safe arrival. We apologize for the inconvenience. In the mean time, we recommend shipping your parts FEDEX using the shipping instruction found here or on our SHIPPING INSTRUCTIONS PAGE.

Our Valet Slide Service is a complete shipping solution for your slide customization. After you place your Valet order we'll send you a prepaid envelope and heavy duty packaging materials to securely package and ship your slide to us for customization.

Yes! Please see our LE Sales page for details! We use VerifyPass to issue unique discount codes for use on our slide milling services.


I'm new to pistol mounted red dots, what optic do you recommend?

In our experience and opinion, we find the Trijicon RMR series of red dot sights to be the only optics that reliably hold up to the rigors of serious use. In short, the Trijicon RMR is the only optic we trust on our personal carry guns.

The Holosun 407c/507c/508t series of sights can be a great alternatives at a more affordable price, especially for competition use, but we still prefer the Trijicon RMR for carry and/or duty use. Please understand that this is not to say other available brands make a bad product. However, when asked for our honest opinion about the different choices available, our answer is clear.

Please note: The above statement is strictly our opinion and should be taken as such. Maple Leaf Firearms is in no way affiliated with Trijicon or Holosun, and does not receive incentives for recommending their products over other brands.


What does "Irons Forward Configuration" mean? What advantages does it offer?

This refers to the placement of the rear iron sight relative to optic cut. The "standard" configuration is to place the optic cut in front of the factory rear sight dovetail. In the "Forward Set Dovetail" configuration, we will relocate the rear iron sight in front of the optic.

There are pros and cons to both configurations, however we find many experienced shooters to prefer the irons forward configuration once they get used to shooting with a slide mounted optic.

It should be noted that due to geometric constraints, some optics are not able to be placed in front of the rear iron sight in the standard configuration. For example, the Vortex Venom, Burris FF3, Leupold DPP and Aimpoint Acro P1 are too long to position in front of the Glock factory dovetail without compromising the Glock firing pin safety mechanism. If you wish to use Glock style suppressor sights with these optics, the only option is to go with a forward set dovetail.


Holosun 407k/507k - Shield RMSc - Sig Romeo Zero optic cut compatibility:

The Holosun 407k/507k optic uses a unique footprint that is slightly (about 1mm) shorter than the Shield RMSc and Sig Romeo Zero footprint.

Generally, an existing Shield RMSc or Sig Romeo Zero optic cut can be modified to accept the Holosun 407k/507k optic, however the optic will not fit snug in the optic cut pocket so it is not ideal.

The Shield RMSc and Romeo Zero will not fit into the Holosun 407k/507k optic cut as they are longer than the optic cut pocket.


Does your Trijicon RMR cut work with the Holosun 407c/507c/508t?

Yes, our Trijicon RMR Optic Cut is compatible with the Holosun optics. However, due to dimensional differences, the custom length mounting screws we supply for the Trijicon RMR cut ARE NOT compatible with the Holosuns. You will need to use shorter 5/16" length 6-32 screws. These screws are available for purchase here.


Do you make cover plates for optics other than the Trijicon RMR/Holosun "C" Series?

No, not at this time.


What is the typical turnaround time?

Please see the banner at the top of our home page for current approximate lead times. Please note that lead times are fluid and are subject to change without notice due to current workload, and do not include holidays or shipping times.

Can you work on aftermarket slides?

Yes! If you plan to order our customization services for a blank slide, simply put "Blank" in the form where it asks for your slide serial number.


Why do you require a "Serial Number" for your customization work?

We ask that you put the serial number of your factory Glock slide simply so we can keep track of your slide while it's here. If your slide does not have a serial number, as is the case with most blanks, simply put "Blank" in the serial number form.


How does modifying the slide affect the functionality of my pistol?

We extensively test our slide designs for function prior to their release to the public. We do not release products that we feel are a danger to the user, or those that have significant reliability issues. With that said, every individual handgun and shooter is different, so certain modifications may alter the reliability and/or accuracy of your handgun.

Obviously, all of our slide milling services will remove mass from the stock slide. We find that most models continue to function as intended with the factory recoil spring assembly, even with significant slide mass reduction. You may choose to change your recoil spring to a heavier or lighter weight based on personal preference.

As a general rule of thumb, we do not recommend using ammunition loaded to higher pressures than standard SAAMI specifications with a modified slide.


Will my pistol recoil more with a modified slide?

That's a tough question to answer because there are a lot of variables in play. Milled slides will have less mass that the typical factory slide. In general, because of this decrease in slide mass, most shooters will perceive a slightly sharper, snappier recoil impulse as the entire firearm has less inertia to counteract against the forces of the bullet being accelerated. (Simple physics: Every action has an equal and opposite reaction...)

HOWEVER, because the slide is now cycling faster, and there is less reciprocating mass, most experienced shooters will shoot flatter with a modified slide than with a stock slide. As with any handgun, solid grip fundamentals make all the difference with recoil management.


Will modifying my firearm void the factory warranty?

Slide milling and frame modifications will almost certainly void your factory warranty. Drop in replacement parts alone, may, but are much less likely to, void your warranty. It is your responsibility to know what is covered under your warranty.


What is the Order Cancellation Policy?

Please ensure your order is entirely correct prior to finalizing your online order.


If you wish to cancel a pending order containing any slide customization services you will be charged a 25% cancellation fee of the total value of the customization services. The remainder of your payment will be refunded to your credit card.

Cancelled or returned orders for any items other than slide customization services will be subject to a 10% restocking fee.

Due to the increased administrative processing fees associated with the Sezzle buy-now-pay-later service, orders financed using the Sezzle option are not eligible for cancellations or refunds.

What is the Return Policy?

You may return most new, unopened (unused and uninstalled) items within 30 days of delivery. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect item, etc.). Due to the nature of the products we sell and for liability reasons, used or installed items are not returnable. Ammunition is not returnable.

You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).

For obvious reasons, all of our custom work is non-returnable, however, we guarantee your 100% satisfaction. In the unlikely event you are unhappy with our custom work, we will work with you to come up with a solution.

If you need to return an item, please Contact Us with your order number and details about the product you would like to return. We will respond quickly with instructions for how to return items from your order.

Note: All returns not due to an error on our part will incur a 10% restocking fee plus original shipping costs.
