Look at a base SP01 Shadow for $880 and shipping.
Better sights, controls, has three mags add a couple of Springs.
better value for initial outlay of cash.
91254 is nitrite slide with polycoat over nitrite lower.
91255 is urban gray polycoat over nitrite
91256 is nktrite over nitrite
91257 (2018) is the 91254 with blue grips.
balance of weight and springs. need lighter comp, light springs to get the gun to cycle correctly and effectively.
mine I use a little hotter factory ammo to get the slide speed up and the comp to work a little bit.
