Ar-24
I am very interested in this gun, feed my pistol about 1,000 rounds a month for USPSA matches and practice, and am NOT happy at all with the quality of my CZ 75B. I am looking for a higher quality implementation of the CZ75, and think the AR-24 might be the solution as I am not going to pay $2k for a Phoenix.
I have only three concerns with the AR-24 for practical competition. First, slide stop breakage, which I assume soft loads will make unlikely, 10-round mags for California, and the rounded trigger guard. My PX4's trigger guard has the same shape as the AR-24 and it almost sucks my finger into the guard. This might be needed for a carry pistol, but I don't want to get DQ-ed from a match because the guard doesn't properly support the finger during gun "management" tasks. (I also wonder how safe this makes a carry pistol as this is a real-world safety concern)
Actually, for competition I would like a super-heavy duty trigger guard to add weight right at the CG so I get weight without producing a pendulum effect as with weight out on the chin, or at the end of the mag, as with the CZ-SP01. If a competition AR-24 weighed in at 1185 grams, like the SP01, and put the weight in the hand, instead of on the chin, it would have a substantial advantage for producing accurate double-taps.
The only feature I would not tolerate in this gun is going away from the CZ grips. The palm-swell is such a critical feature for acquiring and holding a correct grip that lacking that I would NOT have any interest in the AR-24. The palm-swell is so critical to holding a proper grip I have come to the conclusion that people who buy guns that don't have them have never learned how to hold a pistol properly. For those of us who actually shoot guns, and do so proficiently, "cool looking" is not a feature.
I know that very minute features make or break pistols, so it doesn't surprise me that a lot of posters here don't "get" the AR-24. Greyrider, or anyone, as soon as you can find a way to get one into California please let me know. TVMIA.
PS: The K100 Grand Power is an interesting gun, but I think the Beretta PX4 and Cougar are better implementations of the rotating barrel lock.
