Hiya, I was given a MGC SAA on the weekend, its in pretty good nick, need a reblue but nothing major. One thing I noticed was the hammer sits flush with the frame so I cant see how it would have ever struck the cart. Looking at another MGC I have, I can see its had a 'pin' added to the hammer so it strikes the cartridge. Ive got some 5mm bar and have no issue drilling the hammer on the new one and adding a piece of bar so the gun fires but am I missing something? How did they ever work without modification? The hammer doesn't look modified or worn at all.
