Brownells
GunTech Tip
In
1971 Browning introduced a “sport” version of the
Hi-Power which
featured a windage and elevation adjustable rear sight. Since
it’s
inception the “sport” model has used three
different styles of
adjustable rear sights. Browning, in later parts lists, refers to
these sights
as: Type A, PO57341, Brownells #149-001-062; Type B,
PO55536, Brownells
#149-001-002; “Millet Type”, PO55547, Brownells
#149-001-011.
The Type A is what is commonly
referred to as the
“BLR” style rear sight. This sight was the first of
the adjustable
rear sights used on the “sport”. This sight used
many of the sight
parts from the Browning BLR lever action rifle. The identifying
feature of this
sight is the that the sight blade is made from a round steel
tube, windage
adjustments are made by loosening and tightening opposing
screws on each end of
the blade tube, the sight body has a triangular shape. The
width of the
dovetail cut in the slide for this sight is a nominal .368 inch.
The
Type B is the least common of the adjustable rear sights on the
Hi-Power. This
was second patten of sight used, for a short period of time
between
approximately 1982 - 83. The sight is distinguished by
it’s compact boxy
shape, similar to the rear sight on early Buckmark 22 pistols.
This sight was
made by an outside vendor, A.T.I. located in Utah, for Browning.
Front to rear
the sight has a overall length of .920 inch and a nominal
dovetail width of
.368 inch.
The “Millett” type, as the
name implies, is the
typical rear sight unit as manufactured by Millett. This sight
replaced the
Type B rear sight and is still standard equipment at the time this
is written.
The dovetail cut in the slide for the sight is nominal .375
inch.
