Getting the right fit
Fit is everything with gun parts. Match the exact make, model and generation of your firearm, since a Glock 19 Gen 3 and Gen 5 do not share every part, and AR-15 parts can differ between mil-spec and commercial dimensions.
Barrels and muzzle devices also need the right thread pitch. For triggers and internal parts, a qualified gunsmith install is the safest route if you are not comfortable doing it yourself.
Gun Parts FAQ
How do I know a part fits my gun?
Check the product title and specifications for your exact model and generation. If a listing covers a range of models, confirm yours is on the list before ordering.
What thread pitch do I need for a muzzle device?
Check your barrel. Most 5.56 and 9mm barrels use 1/2x28 and most .30 caliber barrels use 5/8x24, but confirm the thread on your barrel or in your owner's manual before you order.
