Hello mate, unfortunately because you got the RAC version, you might struggle with the writing.
Its the version with the most writing i have ever seen on any gun lol.
IF you start rubbing away at it, you will most likely effect the paint, the trades and markings are lasered on so it imprints the metal slight too, and because of the colour of the paint you cant use a bluing pen on it.. So i think its either put up with the writing, or remove the letting and paint.. (either polish the pistol or get it repainted)
As for the magazine, any of the KWC 1911 variants will fit it.
Ring ronnies they should get some back instock soon.
