From Hickok45 – he points out the big difference right up front – fit and finish is the biggest driver of manufacturing costs – they both shoot well – it’s the bling thing at play more than functional differences . . .
My favorite carry piece is a RIA GI 1911 ( looking back through a bunch of posts I don’t think I ever reviewed it – I will have to remedy that ! ) – I upgraded the grips / sights / recoil spring – and the recoil spring upgrade to a Wilson Combat flat wound spring had nothing to do with ant functional aspect – it just”felt” different recoil wise than the Sig Tac Ops – so I swapped out the recoil spring . . .
Have Fun! – Run the Gun! – and remember – Fish Heads are Cheap!!
