Also, petty I know but the chassis pin has been pushed through the wrong side and is halfway out, it's making my eye twitch. Your professional tech should have known better.

Realistically, you *might* be able to sell the G18C with one mag for £150-£200

the drum mags sell second hand for £100. You could sell that separately. 
 
the extended mags sell for £25-30 second hand. Again, sell separately.
 
Theres not the market for “nearly new” TM G18Cs to command nearly new price. Typically £200 is about the ceiling for gen3 TM glocks. You’ll be waiting a while for a buyer at any price higher unless your glock is super rare or Gucci.

bbgun4less have mags in stock, bit pricey tho

just bb guns have we svd for sale for a reasonable price
