About the Tommy Armour 845s Silver Scot
The 845s Silver Scot is one of the best-selling irons ever made: designer John Hoeflich's investment-cast "Cavity Balanced" design was introduced to the Tommy Armour sales force in August 1987 and went on to sell more than 660,000 sets over a roughly seven-year catalog run, shipping over 30,000 sets in 1988 alone against an original forecast of 7,500. Hoeflich set out to duplicate the Ping Eye2's consistent centre-of-gravity placement in a traditional Wilson Staff/MacGregor-style profile, with a straight leading edge and progressive offset, and its success pushed Ben Hogan to answer with the Edge. The full range ran 1-iron through four wedges — PW (48 degrees), W3 gap wedge (52), SW (56) and W4 lob wedge (60) — in right and left hand, with ladies' models alongside. Stock shafts were True Temper-made Tommy Armour Tour Step (X, S, R, A and L flexes) or True Temper Dynamic Gold, with swing weights from roughly C8 to D2 depending on flex, and Tommy Armour Victory grips by Golf Pride. The specs below are from Tommy Armour's own 1988 Golfer's Guide catalog (36-degree 7-iron); note that a widely copied online spec database instead lists lofts about a degree weaker (35-degree 7-iron) with quarter-inch-longer lengths, a conflict documented in the sources.
Stock shafts
- Tommy Armour Tour Step (by True Temper) — steel · flexes: X, S, R, A, L

Frequently asked questions
What is the loft of a Tommy Armour 845s Silver Scot 7-iron?
Per Tommy Armour's 1988 catalog, the 845s 7-iron has a loft of 36 degrees, with a 61.5-degree lie and a 36.5-inch length. A widely copied online spec database lists it at 35 degrees and 36.75 inches instead; the catalog figure matches designer John Hoeflich's own description.
Why are the Tommy Armour 845s irons famous?
They are one of the best-selling iron models in history, selling more than 660,000 sets over a roughly seven-year run from 1987. The design put Ping Eye2-style consistent centre-of-gravity placement into a traditional-looking investment-cast head, and its success prompted Ben Hogan to launch the Edge in response.
What wedges were available for the Tommy Armour 845s?
Four: the 48-degree pitching wedge, a 52-degree W3 gap wedge, a 56-degree sand wedge and a 60-degree W4 lob wedge, all at a 63-degree lie and 35.5-inch length.
What shafts came in the Tommy Armour 845s?
The custom-fitted Tommy Armour Tour Step shaft, made by True Temper with a high flex point and low torque, in X, S, R, A and L flexes, or True Temper Dynamic Gold in X, S and R. Stiff-flex sets ran light swing weights of about C9 to D1.
Finding a used set
The Tommy Armour 845s Silver Scot ran from 1987 to 1995 and is no longer in production, so the used market is the only source. Search eBay, 2nd Swing, Golf Avenue and the PGA Tour Superstore trade-in listings, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.
- Tommy Armour 'Golfer's Guide Silver Scot 845s' catalog (copyright 1988 Tommy Armour Golf), page scans reproduced in The Hackers Paradise's 'Throwback Thursday - Tommy Armour 845s Irons' article — the manufacturer specifications table for men's right- and left-hand irons (1-iron through PW, W3, W4 and SW: loft, standard lie and length as recorded here), the ladies' iron table, the Dynamic Fitting System length (+/-1 inch) and lie (2 degrees flat to 2 degrees upright) options, the shafts-and-swingweights table (Tour Step X D0-D2, S C9-D1, R C8-D0, L C6-C8, A C7-C9; Dynamic Gold X D0-D2, S C9-D1, R C8-D0), Tommy Armour Victory grips by Golf Pride, U-groove or PGA-Tour-approved V-groove options, and model numbers for men's RH (18450X), men's LH (18452X) and ladies' RH (18454X)
- MyGolfSpy, 'The Story of an Icon: The Tommy Armour 845s' (retrieved via Wayback Machine) — interview with designer John Hoeflich: introduction to the sales force at the American Club in Wisconsin in August 1987, the design goal of duplicating the Ping Eye2's centre-of-gravity consistency in a traditional profile using R.G. Molds investment-cast tooling, the 845 name deriving from PGA Golf's 8350 North Lehigh Avenue address, 'a 36-degree 7-iron and light swing weights ranging from C9 to D1 in stiff flex' (corroborating the catalog table), more than 660,000 sets sold over a seven-year run, and the Ben Hogan Edge being launched in response
- The Hackers Paradise Throwback Thursday article, quoting Hoeflich: 'The original forecast was 7,500 sets and I think we shipped over 30,000 in 1988' — corroborates the August 1987 introduction and first-year volume. year_introduced 1987 is the announcement year; retail volume began in 1988, which is why some references (including the GolfWorks MPF chart, which lists the '845s Silver Scot (original)' under 1988) date it a year later
- CONFLICT NOTE: GolfClubSpec.com (Equip2Golf), the spec database most often copied online, lists the 845s with lofts about one degree weaker (3-iron 21/7-iron 35/PW 47), lengths a quarter inch longer (7-iron 36.75 in) and D1-D5 swing weights. This entry follows the 1988 manufacturer catalog, which matches the designer's own '36-degree 7-iron' and C9-D1 stiff swing weight statements; the database figures may reflect a later production revision or independent measurement, and per-club offset and bounce are omitted because they appear only in that conflicting source
- GolfWorks Maltby MPF ratings chart (golfworks.com MPF_TOMMYARMOUR.pdf) — lists the 845s Silver Scot (original) with a 677 MPF rating in the Game Improvement category, basis for the category field, and the 855s Silver Scot under 1995, basis (with the roughly seven-year catalog run) for year_discontinued 1995 and the successor field
