About Custom Slide Kits
Custom Slide Kits is an online shop for pistol slides, slide kits, optics cuts, threaded barrels and the optics-ready pistols they fit. No showroom: a live catalogue, plain fitment information and a checkout that knows which items are parts and which are firearms.
We are a dealer, not a manufacturer, and brand names on the site say only what a part fits. Parts ship to your address where state law allows; complete pistols and serialized frames ship to the licensed dealer you name, who completes ATF Form 4473 and the background check before releasing them. Unfinished frames, the tooling to finish them and suppressors are not sold. We also keep city guides for 20 cities, with who issues carry licenses, the hunting zone and the nearest public ranges.
How we work
- Online only. There's no showroom to visit. Everything is ordered here and picked up at your own FFL dealer.
- Live price and stock. What you see is checked again when you order.
- Every firearm through an FFL. We ship guns only to licensed dealers, who complete the background check with you.
- Straight answers. Ask us anything before you buy — about a model, a caliber, or how a transfer works.
What we don't sell
We don't sell NFA items (suppressors, short-barreled rifles or shotguns, machine guns), and we don't ship items to places where they're prohibited.
