    Some people say it doesn't matter, some do. When I bought my XDm 3.8 I didn't even know the term.

    In the past year I've gone from an SR9, to a CZ75b, XDm 3.8 9mm, and now an M&P9.

    Out of the 4 the XDm is easily the hardest to shoot "fast". It's accurate sure.. Probably equal to the CZ and M&P. But once you start double-tapping the XDm starts to fall behind. I would say that's it's only downfall.. Everything else about it is amazing... Especially the trigger.

    Yes, after enough practice, you can learn to "control" the muzzle flip on the XD... But it dawned on me after shooting the M&P that I was working really hard to keep tight groups while shooting fast with the XDm.

    So yes, the XDm has a high bore-axis and yes that means it's going to be harder to shoot "fast". If you're not concerned about speed, (read competition) then it probably isn't an issue.

    Oh and for those that don't know what "bore-axis" refers to...

    It's basically the center line down the middle of your bore.... What's important is how high this line is above your hand. The higher the bore axis the more the muzzle is going to flip.

    Kind of why I'm excited for the Chiappa Rhino.

    I had the same problem with my xd40 service. I bought an fnx a few months ago and made it my carry since. The xd is the easiest to clean and the fnx is a pain.

    Either way, I always preferred a hammer system.

    I put a PRP trigger kit in my XDM 4.5 inch .40 and I have no problem double tapping tight groups. However, I have always shot XDs.... I hate any other feel except a 1911. lol

    Even without the PRP trigger the XDm probably has the best trigger of any polymer. IMO.

    Don't know that I have the same experience/observations.
    How exactly high is the bore axis?

    At 3 and 7 yards my rapid fire double taps are on point with my XD Service. Even at 10yrds I'm combat accurate. But I've not tried any other pistols. I don't think I can do any better with something else.

    I personally can shoot better double taps with my XD than with a glock, or anything else for that matter. May just be that I'm more used to it.

    Not sure how accurate you're trying to be but I can pretty consistently put a double tap in a 4" circle from 7-10 yards with my XDm 4.5. That's good enough to be combat effective.

    I can do the same with my Glock 19, which has a much lower bore axis, but I don't know that it's any easier.

    The FNX has a lower bore axis than the FNP. I was doing great with the XD but the first shot was always the errant shot that works against me. I picked up the FNX and by the second weekend my first shots are always within 1 inch from bulls eye from 10 meters and 1 1/2 inches from 15 meters. I rapid fire the mag, the range I go to doesn't give me any flack on it even though its posted no rapid fire.

    All the guns are tools, its which one mates well with your hand.

    ^^^Same here

    I mean, how accurate are you trying to be? I had good results with my service but I'm finding I can control the sub even better.

    Is there an unbiased table of bore axis of various handguns? How much of a difference is there in actual distance between them? 1/64th of an inch? 1/4"? 1"?

    I've honestly can't say that my poor shooting was caused by bore axis variation from one model to the next.

    Technically, yes. What FN did was they raised the rear part of the polymer frame (where the body curves to protect your hand from being hit by the hammer) so your hand sits a bit higher on the grip than on the FNP. The size of the slide and the way the barrel and spring are positioned are exactly the same. An interesting solution that actually works. :cool:

    I am the very same way. I feel a big difference between the M&P and the XDM 4.5 where the M&P is much easier to do follow-up shots with. The same thing happened with my FNP-9 and the Ruger P345 where I had a much easier time getting in faster follow-up shots that were also more accurate with the FNP compared to the P345. This is why I am thinking of going for the SR9, for it's low-bore axis like the M&P. The FNX as well. Even a little seems to go a long way for some people.

    If you're seriously going to complain about the accuracy of your double taps, then go right ahead. It's your right to complain.

    But how fast do you really need to be and how accurate do you really have to be? If I can shoot mine accurately enough and quickly enough at typical combat handgun range to hit a pie plate several times in a few seconds, that's good enough.

    All I want is to survive any situation where I would have to shoot to defend myself. For that, the XD will do very well.

    This is my first time ever to shoot rapid fire a few months ago. This is at 10 yards. The target is the size of an average man's torso. Not those giant CHL targets. XD9 Service not even broken in yet. Less than 500 rounds. This was as fast as I could pull the trigger, combat accurate, which was what I was shooting for. I've gotten better since then. Especially after the pistol broke in. At 3 and 7 I'm getting 3" groups. Bone stock XD.

    Only way to backup your claim about bore axis is to show us measurements and differences between teach pistol. Anything else is just one mans opinion with no data to support it.
    I've shot many different pistols and I've never noticed a difference. Never have I said "WOW this gun is recoiling much more because of the high bore axis." I feel more recoil difference when shooting a lighter gun vs a heaver gun than a 1/4" or less bore axis difference.
