I'm also glad to see a Browning forum here. Like Dave I also have some older models - side by side 20 guage, Sweet Sixteen, BT-99, .22 auto, T-Bolt, Safari grade .308 with the Mauser action, 52 Sporter, 71 carbine, 92 carbine in .44 mag, and a Jonathon Browning mountain rifle in .50 caliber.
Also a GP High Power and a model 125 .380 semi auto with target sights and thumbrest grips, with a grip safety that sounds a whole lot like the gun Dave describes as a model 1071.
I hope to see a lot of Browning discussions in this new forum.
EDIT: Just did some research, Browning calls their version a model 10/71, FN calls theirs a model 125. Identical guns although the grips appear to be different. Mine is the Browning but I saw the 125 designation in 'Small Arms of the World' and there is no model number on the gun anywhere, so I've always called it a 125. Guess I need to update my records.
