Here is something not really vintage but could be fun or maybe you have a newer 1911 clone you want to accessorize.
Laser grips with a tiny little allen wrench to make minor adjustments with to the aiming mechanism.
These are not Crimson Laser quality at all they are fun little grips that may help you acquire your target faster, it is not meant to replace your iron sights.
Sometimes just the little red dot is all you need to defuse a situation.
I will include new lithium batteries with the sale and test it before I mail it. For an electronic device at this price my warranty will be limited.
