So , I'm thinking of getting 357 , and after looking at all the options , I've decided on the Colt 686 . I've googled the Pre/Post lock issue and am still not clear on the issues. I think the post lock model can some how lock on you ,so you can't fire the gun ? Can you just unlock it? I've seen a used pre lock for $800 and a new , I'm assuming post lock for $1000. So , does pre or post really matter much?.. Thanks
