Ported Uppers

Ramped vs. Non-Ramped
- 1911 frames either have a ramp or no ramp. Please field strip your 1911's slide off to see which one you have. -A ramped frame needs a non-ramped barrel and a non-ramped frame needs a ramped barrel.

-See image below for an example: (Left is Ramped. Right is Non-Ramped)
