Hi Guys. Sorry to say my first post to this wonderful forum is sort of long, but having been a huge P7 fan and having just been bitten by the 1911 bug, I have put a lot of brain cycles in comparing these two wonderful guns:
I have a Tripps HC'd P7M8 with factory sights that have had tritium inserts installed and a Kimber Series 1 Custom that has gotten the full up MCSOCOM treatment (with the exception of the markings, it is pretty exact). I have about 5K rounds through the P7 and 2K through the ICQB 1911...
All things being equal, I think the P7 has slightly more inherent accuracy then the 1911 and is head and shoulders above the 1911 in 'practical' accuracy. From the bench, I get equally good groups (2" for both at 25yds, but I also don't have much bench experience, so that's a huge factor I am sure).
The P7 is simply an easier gun to shoot well; less recoil, the gas system is so very very smooth, the barrel is mounted extremely low and a 10 year old can control the recoil. I can put 9 rounds of ammo downrange and into the A Zone of an IDPA target in less then 3 seconds (from the ready @ 10 yards). I am not trying to boast about my own skill here, it really is all about the gun; I cannot reproduce those results with any other 9mm pistol, and can't come close with the 1911.
Furthermore, all of my friends (non-gun owners) find the P7 kiss simple to shoot and have a great time with it while 2-3 magazines through the 1911 usually has them saying "Ok, that was fun, got anything smaller?" I think this is an important data point because if a novice finds shooting one gun easy compared to another (accuracy being equal between the two), someone with experience can probably take advantage of that to great reward.
I think the P7 gains a huge portion of it's advantage from being a 9mm pistol. I would really like to try a 9mm 1911 and get a better idea of how each platform compares to the other. Better yet, how about someone sends me a P7M7 (the extremely rare, only 6 ever made, .45 version of the P7) and I will shoot a few thousand rounds through it and do a full review!

P.S.
All that being said, my MCSOCOM clone is a really amazing pistol to own. The thing feels like it's milled from a single block of artillery iron and detail stripping it is a journey into genius. I am still utterly amazed that this object was designed almost 100 years ago...
