The Imperial Defence Services (IDS) Ranger series of pistols are of a conventional design based on the Colt 1911A1 self-loading pistol. The pistols have been manufactured using the latest CNC equipment, giving tighter tolerances on mated components. Additional sight options have been provided, as well as increased magazine capacity to meet today's perceived need for additional capacity.
The Ranger series are of conventional locked-breech, recoil-operated design based on the venerable Colt 1911A1 series. Of all-steel construction with forged steel slide and manganese chrome steel barrel, finishes include blue, parkerised or hard chrome. Model types include standard full-size, compact and 'Hi Cap' standard and compact. Early models had barrels with conventional cut rifling and chrome-plated chamber and bore. Later models (2006) have cold hammer-forged barrels, again with chrome-plated chamber and bore. Two calibres are offered: 9 × 19 mm and .45 ACP. The full-size models have the standard single-column magazine and the 'Hi-Cap Compact' models have a wider frame width for a double-column magazine. Optional extras include an extended slide-release, extended safety lever, ambidextrous safety and adjustable sights.
