Customizing my Gov. Colt 1911?

Question

I need to know which adapter rail to buy for this gun http://www.surefire.com/maxexp/main/co_disp/displ/carfnbr/292/prrfnbr/23518/Mounting-Rail. but its too expensive..any suggestions on these products or how else to customize this gun

Answer 1

First of all, that's not a Gov. Colt 1911 [sic].  It is a CO2-powered air pistol which resembles a 1911A1.  You have no guarantee that any accessory made for a real 1911A1 will fit the Umarex air pistol, because Umarex does not have to adhere to any standards for its products.

My advice would be to contact Umarex and ask them what they recommend.  They may even manufacture the rail to fit your air pistol perfectly.  Their contact information is in the link you posted.
