What do you all think of the AMT backup DAO?  My dad just brought me his and asked me to make the slide work smoother.  About 3/4 of the way back into battery it catches a little bit.  If you let it down slow you can make the weapon stick open.  It is getting a little better though.

[b]SEE BELOW FOR FURTHER DISCUSSION[/b]

How many rounds has been fired thru this gun?  I think it has been not been thoroughly broken-in yet.  Maybe a couple of drops of Breakfree on the slide rails, could help.  I have fired a 45ACP version a few years ago, it was okay.  I had problems fully loading the magazine because of sharp edges on the feed lips.  For me personally, I liked the single-stack Glocks better though.

A friend of mine carries an AMT Backup .45. He has let me use it before and it is a very nice gun for conceled carry. I still prefer the Sig Sauer P226 for kickass performance.

Does the AMT have a disconnector like a model 1911?  Perhaps it's that that it is hanging up on.  Probably needs more rounds thru it.

BTW, if anyone has one for sale in southern kalifornia please let me know.  I can no longer get it from out of state and an FFL can't sell it to me either.  It has to be private party thru an FFL.  Another stupid ass kalifornian law...

I figured it out.  The hammer of the double action was was not worn in yet.  Every time the hammer dropped on the DA it got hung up on the still sharp edges of the slide.  I took a whetstone and put some hoppies oil on it and went over the edge a few times.  For good measure I also went over the rails themselves to smooth all the machining marks off of them.  Now it is as smooth as glass.  Thanks for the help.

I seem to remember the AMT .45 backup had like a 16 pound trigger pull,something ridiculous like that.

You can say that again![;)]
It feels damn near that!

With a 16lb tirgger you can be assured that the possibility of an unintented discharge will be rather small.  I had forgotten all about that.

Today I went out and shot my handy work.  In the five shots it had 4 failure to feed and 1 light primer strike.  I can't get the darn thing to go into battery!  Dad thought it was the flat noses of the Winclean ammo catching on the feed ramp, so we tried round nose and had the same results.  
What could be causing this?

I had one of the .380 DAO models the first year they came out. Never had a failure to feed but did have to send it back twice for light primer strikes. It never was completely cured and rather than bet my life on it, I sold it. The size to weight ratio was unacceptable as well, the slide and frame are over built. I like the idea of a good affordable .380 pocket pistol but the AMT isn't the one for me.

Agree with other posts, I'd just keep shooting it if its functioning OK. It'll break itself in.

I must be lucky. I have an AMT 380 backup and I love the thing! I have put four different types of ammo in the clip trying to make it jam and it has chewed through everything I've put in it. I guess I just got a good one! Good luck with yours.

This one is .45 ACP.  Could the mag be something to do with the FTF?  The mag is basically a short 1911 mag.

I bought my 45 DAO a few years ago. I had no problems with FMJ ammo but using Black Talons it would not feed at all. They would nose dive into a part of the frame on both sides of the feedramp. The front of the bullet would'nt even make it to the feedramp
So I trimmed back the excess material, which to me, looked like it should have been removed at the factory. After that was removed the bullet would then make it to the feedramp but, of course, the feedramp was at the wrong angle. It was a bit too steep & the round would bottleneck almost every time.
So, fortunately the Dremel tool was still out so I changed the angle & polished the hell out of it & now it runs like a champ on any ammo I feed it.  
Of course the other option I had, & so do you, is to send it back to the factory & let them fix it. That would have been easier for me but the tinkerer in me said, naaaahhhhhh!!

I don't know if this helped you or not but it might give you some ideas on what else to look for.

I agee with ECS.  Keep shooting it until it breaks in.  I put thru 3 mags on the gun tried, and worked flawless.  AMT guns had a rather variable quality control, some guns worked like a champ, some not at all.  Since Harry Sanford the original owner died, the organization that manufactured your AMT DAO has been sold.

I can't say I have ever seen anything from AMT that worked.  The Break-Up in any of its configurations is a gigantic POS.  I saw a .380 one break, and shot a .45 that was arguably the worst gun I have ever shot.  It took two fingers to pull the trigger with its Schwarzenegger-class pull, and even after that light hits were the rule of the day.  And it failed to chamber about half the time.  It handled like a brick and was about as heavy.

What was the question again?

They are just Shitty guns!

I did a little more smoothing and will test it tomorrow.  Thanks for all the suggestions, I will keep you updated.
