The HS2000 would normally be in the Stock Service Pistol (SSP)division along with the Glocks, but could also be used in the Enhanced Service Pistol (ESP) division, as per the IDPA rule book. I don't know why this is, as it allows some people to game a major match by signing up for ESP where there are usually fewer shooters. This has the effect of moving them closer to metal/trophy if they are pretty good, but not good enough to snag at least third in SSP. I think that ESP may eventually be limted to single action pistols with mag capacities over 7 and calbers less than 45. Personally, I would like to see the divisions go away and add a few more levels to the classifications. This would cause shooters to drift towards weapons that work best and allow them to move up to new challanges (read classifications)as their skills improved. If you plan to use your HS200 in IDPA, I cannot recommend it enough. I have stopped using a Glock for IDPA and started using my HS2000 exclusively. It is more accurate than the Glock, even with an aftermarket barrel, and the trigger breaks cleaner - more like a 1911. The HS2000 seems to have a weak trigger return, but so far this has not slowed me down any. If you have trouble finding a holster, any IDPA approved leather holster for the smaller Glock frames (17,19,23,32 etc.) can be made to work. Simply wrap the HS in very thin plastic, soak the holster in alcohol enough to wet it, then insert the HS and allow the holster to dry. Afterwards, treat the holster with a good conditiioner and presto an HS2000 holster. The mag pouches seem to work fine without modification - at least mine did.
Good Luck,
