IDPA Classification

[Hawkmoon]

After reading through the IDPA rule book, I am just as unclear now as I was before as to what class or classes a 1911 would fall in for IDPA competition. What class does a stock, full-size, single or double stack 1911 fall into?

Does a stock Commander length 1911 (single or double stack) fall in Compact Carry Pistol?

That would be CDP, or ESP for 45ACP. A 9mm would be ESP only.

Commander length more than likely will not fit the box, and I very much doubt that the double stack would fit due to the thickness.

I have read that a stock Commander with GI sights and flush magazines will JUST fit the CCP Box. I have not tried it largely because I do not have a Commander with GI sights.

Thanks. The ammo I'm shooting doesn't make the 165 power factor, so CDP isn't going to be my division. It looks like it'll be either ESP or CCP. The P13.45, which is what I intend to shoot, has an "intermediate" length grip frame, holding one less round than the full-size P14.45, so it may fit in the CCP box. If so, I'll shoot in that division. And that will leave me the option (I hope) of also shooting a single stack Commander, in either .45 ACP or 9mm.

Hmmm ... I don't have a box, but I just drew the outline of the CCP box on paper, and it looks like the P13.45 misses by about 1/16th of an inch. The magazine base is the culprit -- if the mags had flush floorplates, it would fit.

Oh, well.

Hawk:

That likely wouldn’t stop you from shooting in local “club” matches, where it would in a “sanctioned” match for CDP.

That said, it’d most likely fit in the box for ESP, though 10+1 is the most you can load anything in IDPA.

A SS Commander in .45 acp will put you in CDP. The same gun in 9mm will be ESP.

A Commander in .45 ACP won't put me in CDP, because the ammo I load doesn't make 165 power factor. It's around 130 PF, so that means I'm CCP if it'll fit into the smaller box, and ESP if it doesn't fit the smaller box. I might as well declare for ESP, because that way if I decide to shoot a P14.45 instead of the P13.45 I won't have to change divisions.

I have a Tisas M1911 A1 http://www.trabzonsilah.com/en/firearms/zig-m1911-a1. Will I be able, without mods yet, compete in CDP? I load above 165 factor and tested on my Chrono 751 ft/s

Without modifications, it appears to me that you can shoot in CDP if your ammunition makes the 165 power factor. If the ammo you load is 230-grain bullets, the velocity you report works out to a power factor of 172, so you should be okay.

I just read your post on proposed modifications. I would have to review the rules, but with that many changes I think it might kick you out of CDP.

Thanks I reload with Frontier CMJ 230 gr.

[Hawkmoon]

So your power factor is 172 and a fraction. You are okay in CDP. I posted the rules for pistols in CDP in your other thread. I was wrong -- it appears that your intended modifications are IDPA-legal. Then the question is whether or not they will return enough "bang for the buck" (or bang for the Krugerrand, in your case) to be worthwhile.
