We are pleased to offer shipping via UPS Ground or 2-Day Air for all items.
We are committed to ensuring your satisfaction. If you find any non-firearm merchandise defective upon receipt, we will gladly accept returns and provide your choice of a replacement item (subject to availability) or a full refund. Please note that Arm Safe Supply cannot be held responsible for items damaged during shipping. In such cases, we kindly ask you to file a claim with the carrier. Should you receive a defective item, please call us immediately at +1 713 766 9931 to request a return label.
We kindly request that you thoroughly inspect all firearms before proceeding with the transfer. Once a new firearm is transferred to you, it is considered used, even if it remains unfired. As a result, we are unable to provide a full refund for new firearms after they have been transferred into your possession. Please note that we do not reimburse FFL transfer fees on returned items.
We understand that some manufacturer defects may not be identifiable during the initial inspection. If you discover a defect after the transfer, the firearm must be returned directly to the manufacturer for replacement or repair in accordance with their warranty policy. This approach allows you to avoid the additional transfer fees associated with returning the firearm to us through your local FFL dealer.
Please do not send defective firearms directly to Arm Safe Supply. Manufacturer-repaired firearms can be returned directly to you without additional FFL transfer or associated fees. However, if the manufacturer decides to replace the firearm, the replacement must be transferred through your local FFL dealer to document the new serial number.
Please note that all ammunition sales are final.
By using and ordering from our site, you agree to these terms. We appreciate your understanding and thank you for your cooperation.

SIG Sauer P320 Standard Height XRAY3 Sights, Round Notch, 8 & 8, NEW.
This is a set of new SIG P320 standard-height front and rear sights for the P320 slides, #8 Front and #8 Rear. These sights will work with most Factory SIG P320 9/40/357/45 slides and the same sights that come on most full-size and compact slides. Rear sight features round notch for quick sight alignment. Ideal for use with factory and aftermarket slides. Should fit most P320 slides or aftermarket P320 slides with factory dovetails. May fit other P-Series pistols (P220 .45, P226 .40, P938).
Includes: SIG Sauer P320 Standard Height XRAY3, round notch sight set (#8 front and #8 rear).
No Slide, chamber flag, grip, etc. included
PLEASE NOTE: The higher the front size number, the lower the height of the sight. For the rear sight, the higher the number (i.e. 8), the higher the height of the sight.
EXAMPLE: If you wanted a taller front sight post and a taller rear sight, choose a #6 front sight / #8 rear sight. #8 front / #8 rear point of aim would be higher than #6 front /#8 rear.
