    Hey! I picked up a nice stainless steel .45! It's in great shape, and will be going to the range tomorrow. I understand that this manufacturer went out of business a while ago (Arcadia Machine Tech.), but looking ahead, where can I possibly get parts for this gun? It is one of the smallest 45 auto's made (5 round) and operates only on double action, so the trigger is by design pretty heavy! I would like to replace the hammer spring eventually.
    Thanks!

    Not a chance
    You have a back up designed to be shot little and carried. Look at gun parts corporation to find parts..

    This is more a collectible.
    Don't plan on using it as a CCW gun!

    Get, and use, stainless steel lube on the slide rails!
    Those AMT guns galled VERY badly, hopefully your new one is not.

    This one is in very good shape. Had it apart already and looks like it had very little use. Still would like to replace the strong hammer spring though.

    I had one like that years and years ago. It worked fine but that trigger pull had to bet 20 pounds. I ended up cutting some of the spring off to lighted it. Not sure about parts.

    The hammer/mainspring is a very important part of the guns operation and I wouldn't change it.

    The mainspring is actually what keeps the gun in battery while the bullet exits the barrel. The force of recoil has to overcome this spring in order to operate the action unlike most designs which use a stout recoil spring. (1911's and other hammer designs normally use a combination of both)

    Take a look at how wimpy the recoil spring is. It's only function is to return the slide to battery.

    Shoot it as is and if it's a good one like mine was you will enjoy it. Just don't trade yours off like I did.

    Mine was a great and reliable belly gun.

    There was a gunsmith by the name of John Jardine that used to slick the little buggers up and put real sights on them but I don't know if he still works on them or if he's even still alive.

    Comrade Happyguy :)

    Hey, thanks for all the great comments and suggestions! I guess I will not tamper with it after all, especially when I don't see a lot of replacement parts available. Even on Numrich, the AMT shown is not the older one that we are talking about. How about that stainless steel lube mentioned above? Not sure I ever heard of that or saw it, but would be interested in using it on the slide slots of course.

    If you use it as CCW make sure you have a Lorcin as a back up for it.

    Well, that's one thing that could make an AMT even less likely to go bang when you pull the trigger. I had an AMT .380 backup once...for 24 hours.

    Like everybody else, I assume it's an AMT Backup .45 and not an AMT 1911.

    Ok, so I went to the range today and fired off 50 rouinds of Magtech. Overall the gun fired fairly well, no failures of any kind. Actually it was quite accurate. One problem; approx. 3 times, on seperate occasions, a live round was ejected between fired rounds! I was quite surprised when I loaded up 3 rounds and fired off only 2! I was thinking where did the other round go? Found it on the floor. This happened in between rounds, and not the first or the last round. The following live round always chambered normally. What do you think?

    Not exactly sure what would cause that but the magazines are essentially shortened 1911 magazines. My guess is either the magazine springs are weak and the rounds are shifting forward under recoil, or the feed lips are spread, or both.

    You might try asking this in the 1911 forum, those guys are real trouble shooters over there.

    My "gun guy" suggested to try another .45 mag and indicated as you noted, that even a larger capacity mag may work and only stick out the bottom. I will try that too, mean while I did bend in the lips a bit. Kind of a squirly thing to do since the mouth has to remain reasonable open to feed the rounds into the mag. Thanks again!
