New Business Hours — By Customer Request
GS Custom has served the Tampa Bay firearms community for over 40 years, with an average workweek of 60 hours. Looking forward to our eventual retirement in the next year or so, we have decided to slow down the pace a bit. We will continue to offer a range of firearms services, including gunsmith services, gun repair, installation of gun accessories, such as scopes, sights, trigger kits, as well as gun cleaning and inspection, and firearms training.
As we transition to a fully service-based business, we will not be keeping standard business hours. We will be open to the public on Thursday and Friday and on an appointment basis Monday through Wednesday. You may make an appointment either by email at gscustom@netzero.net or by phone at 727-541-2200.
New Weekly Schedule
| Monday — Wednesday | Appointments Can Be Arranged | |
| Thursday and Friday | 6:00 a.m.— 6:00 p.m. | Call to Confirm Availability |
| Saturday and Sunday | Closed |
Please call Gary at 727-541-2200 before coming to the shop. This ensures that we will be there and able to give your issue our full attention.
Custom Ammo Loading Available
We have closed out our ammunition inventory and have discontinued this part of our business. However, we will custom load ammo for you on demand.
If you want to supply the brass, projectiles, primers, and powder, we will load the ammunition for you. Call Gary at 727-541-2200 for a quote.
Rescue Your Flood-Damaged Firearms
We Still Receive Flood-Damaged Guns In 2026

The hurricanes of September and October 2024 caused devastating damage throughout the Tampa Bay area. The storms resulted in thousands of damaged firearms. We continue to receive these firearms in batches from a few to as many as 150 at a time. If you have damaged firearms, contact us immediately to help you preserve them.
Gary is on a mission to save as many of the handguns and long guns our customers continue to bring us. Fortunately, we have been successful in getting them back to their owners on a rapid basis. We have had several individuals who have brought us firearms left at other shops that were not able to complete the restoration on a timely basis. The critical restoration process requires fast action to restore them to their original condition and return them to their owners. Time is the enemy of a completely successful restoration, so don’t delay.
The rehabilitation process for each firearm involves removing all the rust possible, ultrasonic cleaning and lubrication, and performing a detailed inspection to ensure proper operating functionality. Do not ever attempt to use damaged firearms, as your life can depend on it. Protect your investment in quality firearms. Call Gary at (727) 541-2200. The fee for performing the rehabilitation process is $40.
Individual Firearms Training
You’ve Got A Gun Now What?

Florida HB543, Constitutional Carry, permits responsible Florida residents over 21 to carry firearms. However, firearm owners, and I can’t stress this enough, are legally responsible for every shot that comes out of that barrel. Knowing when and how to legally fire that weapon can determine whether you might go to prison. Owning a firearm is a great responsibility, and knowing how to safely and properly use, maintain, and store it can help you avoid many costly mistakes.
It seems like the harder the left tries to limit and deny the Second Amendment, firearm ownership increases. For months, the news has been reporting high gun sales, implying that there is a record number of new gun owners. As a gun owner, you are responsible for learning how to use your firearm properly and securely. Furthermore, everyone in the family should be educated in firearm safety. Gary, the owner of GS Custom, has been teaching gun owners of all skill levels for decades. Feeling at ease and secure when using your firearm, or any firearm, is critical. The classes are tailored to your specific requirements and schedule. If you want, you can include family and friends. Contact Gary at 727-541-2200 to schedule your instruction.

Please contact us now as gunsmith requests increase as we go into the fall and winter seasons.
