01 / The decision that matters first

The Venus changes the whole package.

The stock photograph is only the beginning. Venus adds a rounded action, demi-bloc barrels, a lighter published weight, and more included wood figure. Zeus offers a lower entry price and more weight in the two directly comparable gauges. Both are customizable boxlocks. [1–2]

Lower starting price

Zeus

$3,499 base

The more economical starting point, particularly with its included full pistol grip.

  • Monobloc barrels
  • Full pistol grip included
  • Standard walnut; flat rib
  • 20 gauge: about 6 lb 4 oz

Lighter published weights

Venus

$3,999 base

A rounded action and an attractive included specification for a traditional upland gun.

  • Demi-bloc barrels
  • Straight or full pistol grip included
  • Grade 2 walnut; concave rib
  • 20 gauge: about 5 lb 8 oz

Official product photographs: Upland Gun Company. Photos may show optional details; the priced menus govern the comparison. Photos are not shown to identical physical scale.

My assessment: Start by handling a Venus if lower carry weight and a traditional straight-grip specification appeal to you. Keep the Zeus in the comparison if you prefer more mass and steadiness, or want its simplest configuration. Neither a higher price nor a fancier stock establishes better fit.

Source: current UGC order pages [1–2]; construction context [7]. No controlled head-to-head accuracy, reliability, or service-life evidence was found in the reviewed sources. Demi-bloc is a construction distinction, not proof of better results.

Compare equal visible specifications

Adding the Venus’s included features to Zeus

Zeus base$3,499
Grade 2 walnut+$400
English straight grip+$250
Concave rib+$250
Zeus subtotal$4,399
Venus with those included$3,999

A $400 advantage for Venus in this particular comparison. The action, barrels, and weight still differ. Tax, shipping, fitting costs, and other additions are excluded. Calculation from [1–2].

Carry weight versus recoil

20 gauge: 12 ounces lighter

5 lb 8 oz Venus
6 lb 4 oz Zeus

At these reference weights, Venus is 12% lighter. With identical ejecta momentum, it would have about 14% more free recoil energy.

Calculated from 6.25 ÷ 5.50 − 1 using SAAMI’s momentum relationship [12]. This is not a measured comparison or a prediction of felt recoil. Actual wood, barrels, balance, pad, fit, and load all matter.

02 / The stock difference you noticed

Grip shape and stock fit are separate decisions.

The grip sets the position of your hand and wrist. Length, drop, cast, pitch, and toe determine how the rest of the stock meets your body. A straight grip can fit poorly; a pistol grip can fit beautifully—and vice versa. [4–6,18]

English / straight

Open wrist position with room to shift the hand. Often paired with double triggers, but it is not restricted to them.

Zeus +$250 · Venus included

Round knob / half

A middle degree of wrist support. The preview calls its intermediate shape Prince of Wales; verify the exact profile.

Zeus +$250 · Venus +$250

Full pistol

A more defined hand position and support. Test the curve and trigger reach without forcing your wrist into position.

Included on both order pages

Simplified grip silhouettes, not scale drawings or RFM manufacturing profiles. Ergonomic observations are practical interpretations; individual hand and wrist comfort must be tried.

03 / Every priced choice

Explore the tradeoffs. Build a working brief.

Select a model, open a category, and choose the option you prefer. Every choice shows both models’ price differences, one benefit, and one compromise. Your selections stay in this file’s browser view; nothing is sent to UGC.

Model for your working brief

“Included” means no listed surcharge on that model; “Not listed” means absent from its priced menu. Prices are the September 27 snapshot. Tradeoffs are research-informed judgment, not measured RFM performance claims.

Two interfaces, different answers. The 3D preview is useful for appearance, but its defaults and options do not fully match the priced order pages. The renderer remained on its loading screen in this review; its public menu text was available. The extra items below are discussion points, not confirmed additions to this calculator. [16–17]

04 / Fit before final specification

Exact fit requires your measurements.

A height, sleeve length, or photograph cannot establish a complete custom stock specification. A fitter should evaluate your mount and eye alignment with a try-gun, then verify the result on a pattern plate and clay targets. The final dimensions belong on your written specification. [3–6]

Where the main stock measurements are locatedSide view: length of pull spans from the trigger to the butt center; drop at comb and heel are vertical distances below the rib reference. The butt angle is pitch. Cast and toe offset are viewed from above or behind, not in this side view.Rib reference lineLength of pullDrop at combDrop at heelPitchCast + toe offset:side-to-side geometrynot visible in this view

Conceptual side view, not to scale. Fitter must specify the exact reference points, front or single trigger, and finished pad thickness. “Drop at comb” alone can be ambiguous: record the nose and face-contact position where appropriate.

UGC’s published reference dimensions [1–3] are not a prescription for you. They are deliberately not copied into your fit fields.

Bring your real context

Take the gun you shoot best, your normal vest and cold-weather clothing, and your gloves. Describe discomfort, hand or wrist limitations, and your typical mix of walking and shooting.

Verify together

Have the fitter check shooting side, eye dominance, mount consistency, hand reach, and shoulder contact. Ask for a representative action and chosen rib/grip geometry.

Approve a written specification

Record the measured dimensions, target finished weight, pad, stock blank, and any remaining exceptions. Confirm fit verification and remedy arrangements before final approval.

05 / Your reviewable specification

Your working brief

Use this as a discussion sheet with UGC and your fitter. It includes your choices, unmade decisions, measurements, and questions to resolve. It is not an order.

Download the brief to preserve your selections outside this browser. No email or order is sent.

Confirm before you finalize

Fit: agreed dimensions, pad thickness, trigger reference, grip geometry, and a clear process if the delivered gun does not match the approved specification.

Configuration: gauge/chamber combination, exact finished weight target and tolerance, both barrels’ specifications, ammunition/proof approval, trigger mechanism, and included choke set.

Cost and timing: final itemized quote, actual stock blank, engraving proofs, case model, tax/shipping/transfer costs, current lead time, payment terms, cancellation policy, and warranty.

UGC lists custom dimensions with exceptions and possible charges, and asks customers to confirm current lead times [3].

Evidence & limitations

Sources you can inspect.

Primary maker, retailer, technical-standard, and shooting-organization sources. Product facts and price arithmetic are distinguished from practical judgments. This is an independent guide, not an Upland Gun Company quotation.

    Audit scope: both priced product menus and their visible add-ons; public text of both 3D-preview menus; general fit, construction, finish, and recoil research. No physical handling, personal fitting, or live-fire model comparison was performed. Some preview-only specifications and artistic patterns remain unresolved; those uncertainties are identified rather than filled in.
