A4s - IPSC's in the US is USPSA - and the community is really starting ton head back to it's roots. I think you would be pleasantly surprised at where the Open Division (aka "Race Guns") are getting more specialized - but with less participation. The Limited and Production divisions are heavily weighted towards more "iron sights" and wea[pons you would actually use in a gunfight. EVEN BETTER.. USPSA adopted a "provisional" "Single Stack" division for pruduction 1911's to further level the playing field and take things back to their roots - basically the only modification you see in this division is mag wells... The emphasis is on your skill as a shooter, speed on reloads, and thinking while acting safely on the course of fire.
The "Race Gun" thing has little appeal for me as well - for the uninitiated the term "race gun " generally means all out modifications - generrally starting out wioth a 1911 that has a lightweight frame, high capacity magazine (15+ rounds), compensators, ammo that is loaded very very lightly (and lower powered recoil springs that go with it), and optical red dot sights. It becomes more of a device than a weapon at this point because they are so easy to shoot accurately.
Shooting production weapons with production powered loads with "real" calibers (something that has a "4" in front of it!) has really made this an enjoyable event.
The nice thing is you can get a young lady or youngman into this activity, typically with a long barreled Glock 34 in 9mm - it's a minor caliber and they compete with other minor calibers untiul they can handle a .40 or .45. We have a niber of 14, 15, qnd 16 year old young men and women that compete quite well at this level and they clearly have a good time.
People will mention IDPA vs USPSA/IPSC. You see a lot more Walter Mitty types in IDPA and more friendly technical competition in USPSA.
