Why do my Buckmark parts look or fit different than yours?
First, although all Buckmarks share many parts, and function in a mechanically very similar way,
there have been changes, both large and small, over the years.
There have been 30+ models/variants of Buckmarks made since 1985.
Major differences between Buckmark models include:
- front sights (post, black ramp, fiber optic)
- rear sights (old style stamped metal, pro-target)
- sight rails (full length or half length, weaver or picatinny slots)
- barrels (4", 5.5", 7.25", 10", 14", bull, tapered/pencil, stepped, contoured, slabside)
- grip frames (standard/UFX, URX, and UDX are grip frames)
- grips (walnut, cocobolo, laminate, plastic, plastic with rubber inserts, 1-piece wrap-around rubber)
Second, guns are mechanical things assembled from manufactured parts.
Every part is made to certain tolerances, but when the parts are assembled,
the variability of these tolerances can accumulate, leading to what people call "tolerance stacking".
That can lead to "if your pistol has a slightly shorter part A, and also a slightly short part B,
then even though aftermarket part C fits perfectly in my Buckmark, it might not fit perfectly in your Buckmark".
Third, Browning has parts (or groups of parts) made for them in batches,
and then has them assembled in model/variant-based "runs" from available parts.
This leads to many minor parts changes/evolutions that can overlap in time or by variant.
That is why, for many changes, it's impossible to say "after this date or serial number,
all Buckmarks definitely have this new version of this part".
Fourth, certain parts are hand-fit during assembly.
Most notably, some surfaces of the hammer and sear (and possibly hammer links,
and pre-2001 firing pins) are essentially "custom fit" for your Buckmark.
This is both good (most Buckmarks work perfectly from the factory, and require no tinkering to be functioning,
reliable, accurate pistols), and bad (replacement of some parts requires knowledge, tools, and care, to get them right).
The combination of model variance, manufacturing parts tolerances, batched parts variance, and custom fitting
usually explains why your parts do not look or fit exactly like my parts.
