Depends on the 'convenience factor' and the condition of the pistola!!
CDNN is selling them NIB for $699 (Commemorative w/ Black grips and TWO 13-rnd mags)... but then factor in FFL fees, any taxes, shipping, etc...
If the gun is in LNIB condition, you're doing OK!... 13-rnd MecGars are about $23 ea...
As DasGuy inferred, NEGOTIATE!!... offer him $650 and have him throw in another mag!... All he can say is 'NO'
