"ATI Firepower Xtreme .45ACP caliber 1911 pistol series from Shooters Arms Manufacturing in the Philippines"

"Shooters Arms Manufacturing, Philippines" Manufacturers of the (famous?) SAM 1911...

 

I just purchased an ATI FX 45 military. It is your standard 5inch barrel 1911. So far, I have put about 200 rounds through it, with one failure to feed.
It was the last round in the mag, and I think it may have been due to me not gripping the gun firmly enough.. I could be wrong. But other than that I have had no problems whatsoever.

Excellent gun for the price (415 w/ tax) and incredibly accurate out of the box.

 

Built by Shooters Arms Manufacturing (SAM) in the Philippines, not Armscor.

Armscor is just one Filipino 1911 manufacturer, SAM and Metro are others.

Here you go.

 

I just picked up two at this weekends show.

1. Commander sized with beavertail and commander hammer
2. Government model railed with beavertail.

Overall fit and finish are excellent, I'll get back to you this weekend on how they fire.

 

Rumoured to be excellent guns

 

So were the Llama 1911's back in the early 80's lol, except then, I fell for it.
