IPSC HANDGUN RULEBOOK, JAN 2004 INTERPRETATIONS OF 6 AUG 2004 INTERPRETATIONS OF 11 APR 2005 INTERPRETATIONS OF 22 JUL 2005 11.8 Interpretation of Rules The interpretations of the Rules listed below are highlighted with additional words shown in bold text, and deleted words in strikethrough. Please note that these are interpretations only not rule amendments. All these and these interpretations are subject to ratification or modification at the next IPSC Assembly. 184.108.40.206 Static paper targets (i.e. those which are not activated) must not be presented at an angle greater than 90 degrees from the vertical. 3.1 General Regulations The competitor is always responsible to safely fulfil the requirements of a course of fire but can only reasonably be expected to do so after verbally or physically receiving the written stage briefing, which must adequately explain the requirements to the competitors. Course information can be broadly divided into the following types: 4.1.3 Penalty targets must be clearly marked or be of a single color different from scoring targets. Penalty metal targets in the general size and shape of authorized paper targets may be used. Penalty metal targets do not have a non scoring border. 220.127.116.11 Cover provided to hide all or a portion of a target will be considered hard cover. When possible hard cover should not be simulated but constructed using impenetrable materials. Whole paper targets must not be used solely as hard cover. 18.104.22.168 Cover provided merely to obscure the view of targets is considered soft cover. Shots which have passed through soft cover and which strike a scoring target will score. Shots that have passed through soft cover before hitting a penalty target will be penalized. All scoring zones on targets hidden by soft cover must be left wholly intact. Targets obscured by soft cover must either be visible through the soft cover or at least a portion of the affected target(s) must be visible from around the soft cover. 22.214.171.124 Hard cover (and overlapping penalty paper targets) must not completely obscure hide the highest scoring zone on a partially hidden paper target. 126.96.36.199 Penalty metal targets designed to remain upright when hit must, if hit, be repainted after each competitor ends their attempt at the course of fire, failing which subsequent competitors must not be penalized for hits visible on their surface. 4.6.1 Range equipment must present the challenge fairly and equitably to all competitors. Range equipment failure includes, but is not limited to, the displacement of paper targets, the premature activation of metal or moving targets, the malfunction of mechanically or electrically operated equipment, and the failure of props such as openings, ports, and barriers. The declaration and/or use of any loaded (see Rule 10.5.13) or unloaded firearm as "range equipment" is prohibited. 188.8.131.52 "Open sights" are aiming devices fitted to a firearm which do not use electronic circuitry and/or lenses. 184.108.40.206 "Optical/electronic sights" are aiming devices (including flashlights) fitted to a firearm which use electronic circuitry and/or lenses. 5.1.4 Unless required by a Division (see Appendices), there is no restriction on the trigger pull weight of a handgun, however, the trigger mechanism must, at all times, function safely and as originally designed. 5.2.1 Carry and Storage Except when within the boundaries of a safety area, or when under the supervision and direct command of a Range Officer, competitors must carry their handguns unloaded in a gun case, gun bag or in a holster securely attached to a belt on their person (see Rule 10.5.1). 220.127.116.11 The chronograph will be deemed to be within tolerance if provided the daily average is within +/- 5% of the applicable minimum power factor varies no more than 5% from any of the previous day's averages. 18.104.22.168 From the 8 sample rounds drawn by Match Officials, 1 bullet is weighed to determine the actual bullet weight, and 3 are fired over the chronograph. In the absence of a bullet puller and scales, the competitor's declared bullet weight will be used. Digits displayed on the official match bullet scales and chronograph will be used at face value, irrespective of the number of decimal places indicated on the particular model of measuring device used at the match. 22.214.171.124 Power factor is calculated using the bullet weight and the average velocity of the 3 rounds fired, according to the following formula: Power Factor = bullet weight (grains) x average velocity (ft per sec) 1000 Note: The underline beneath Power Factor removed. The final result will ignore all decimal places (e.g. for IPSC purposes, a result of 124.9999 is not 125). 5.7.1 In the event that a competitor's handgun malfunctions after the start signal, the competitor may safely attempt to correct the problem and continue the course of fire. During such corrective action, the competitor must keep the muzzle of the handgun pointing safely downrange at all times. The competitor may not use rods, or other tools to correct the malfunction. Violations will result in a zero score for the stage. A competitor who experiences a firearm malfunction while responding to the "Load And Make Ready" command, but prior to issuance of the Start Signal, is entitled to retire, under the authority and supervision of the officiating Range Officer, to repair his firearm, without penalty, subject to the provisions of Rule 5.7.4, Rule 126.96.36.199 and all other safety rules. Once the repairs have been completed (and the provisions of Rule 5.1.7 have been satisfied, if applicable), the competitor may return to attempt the course of fire, subject to scheduling as determined by the officiating Range Officer or Range Master. 5.7.2 While rectifying a malfunction that requires the competitor to lower the handgun down from "on aim" clearly move the handgun away from aiming at a target, the competitor's fingers must be clearly visible outside the trigger guard (see Rule 10.5.8).
