The P09 mags cost about 35.00 US plus you will need this: CZC A01-LD Magazine Base Pad For use on CZ P09 Magazine when used in the CZC A01-LD. Does not add capacity for 29.50 plus shipping.
So the 1911 bushing install is worth $350.00, trigger parts $168(US) , base Shadow 2 $1,200, polished barrel,slide+/- all hand fitted for $1,999. This S2O looks like a good value to me.
The CZ Shadow 2 Orange is very similar to the Accu Shadow 2. It appears to have a few additional features such as the polished barrel and additional hand fitting. There're priced very similar as well..
