Some insight from IDPA on Facebook. ------------------------- Sig P320 X-Five in IDPA While IDPA does not normally comment on the legality of specific gun models, preferring to let the listed rule criteria do its job, there have been a few extra questions on the X-Five. First, the P320 X-Five delivers with four 21 round magazines. While nice, these magazines when inserted make the gun too large to fit the IDPA box. You will have to purchase 10 or 17 round magazines to be legal for IDPA. The X-Five is advertised as having a bull barrel. There is no rule against a bull barrel, only heavy or coned barrels. The X-Five comes from the factory with an added magazine funnel. This funnel does fit the IDPA box and would be legal in ESP. However, this funnel would have to be removed to shoot the gun in SSP. It is a single Allen screw and can easily be accomplished by the end user. The last issue revolves around the advertised “removable grip weight.” IDPA has reviewed the gun and come to the conclusion that this weight is an integral part of the grip from the factory and legal. The weight is not easily removed and reinserted by the end user without the possibility of voiding the manufactures warranty. It is not an “add on weight” as defined under rule.8.1.8. So the gun is legal as it comes with the factory weight. That being said, removing the weight and replacing it with a heavier weight would be illegal.
