History of Police Safety Sear Installation

[Edward Tinker]

see below
What about the remaining questions. Any insight?

3. Would the gun have the sear safety installed and then have the barrel/extension reblued at the same time? Why was the rebluing neccessary?
IT DEPENDS, IF THE GUN NEEDED A NEW BARREL, THEN A NEW BARREL WAS ADDED, IF IT RECEIVED A MAGAZINE SAFETY, IT NEEDED TO BE REBLUED. A FACTORY OR ARMORY SHOULD NOT BE CONFUSED WITH A USA GUNSMITH REBLUE (ONE WHO DOES NOT KNOW WHAT HE IS DOING, NOT SOME OF THE LUGER SMITHS HERE ON THE FORUM)
4. If these guns where recalled from police forces and already had the police markings, how did they insure they got back to the same police force after the refit?
US ARMS ROOMS SEND OFF GUNS TO THIS DAY AND GET THEM FIXED AND SENT BACK TO THE UNIT, JUST PROPER PAPERWORK...
5. What arms did the police forces use during the time when their weapons had been recalled for the refit?
THE OLDER REVOLVERS, OR SENT THEM IN BATCHES AT A TIME AND WERE USING SOMETHING ELSE, I AM NOT 100% POSITVE ABOUT THIS, COULD BE MANY FACTORS....
Plus one new question:

6. If they always made sure that the pistols had correct and matching numbers before they were dispatched, how and why did so many of these Lugers end up in America with mismatching numbers?
TO MAKE GUNS FOR SALE IN THE USA, MANY NON-WORKING GUNS WERE PUT TOGETHER TO GET THEM WORKING; THIS HAPPENED IN GERMANY, IN THE USA, OVERSEAS BEING SHIPPED HERE ETC. MANY, MANY REASONS THIS HAPPENED, IT SIMPLY DID. SOME WERE BY GI'S, BUT I BELIEVE MANY WERE BY DISTRIBUTORS TRYING TO GET WORKING GUNS.
