Fitment questions
How do I know a part will fit my gun?
Every part lists the guns and magazines it is made for, plus any conditions, such as grips that need a magwell cut or a mount that suits only one slide type. If your gun is a variant that is not named, ask us before you order. Unused, uninstalled parts can be returned within 30 days.
Where do the fit details come from?
From each product's own description, which lists the guns and magazines the part is made for and any conditions. Parts marked Fitment checked have also been checked by our team against those guns. Factories change parts between production runs, so if your gun has been modified or is an unusual variant, send us a photo first.
Do 1911 parts fit a 2011?
Some do and some do not. Controls such as thumb rests and safeties are often shared; magwells and base pads are not, because the frames and magazines differ. Each part lists exactly which it fits.
My gun is not listed. Can you help?
