The Old Arminex 1 Piece Backstrap 4 Colt Pistols
Sorry about the extremely poor picture quality. I apologize but, it lost something in the transmission. It WAS slightly better.
Certainly a quite rare item that you do not see every day.
Originally produced (in very limited numbers) by Arminex to eliminate the P.I.T.A. Grip Safety on the 1911 Colt Pattern Pistols.
It was a high quality part and was made very well.
FORGET about ever trying to get hold of one these days.
They have pretty much achieved Collectible Status since not many were ever sold.
They are so scare that most folks do not even bother searching for one of them anymore.
Even the Arminex 3 "Easy Caliber Change" Tri-Fire pistol only ever sold (I think) about 500 pistols. It just never really got off the ground.
