I agree it's more a matter of if you like the gun and can get a good site picture with it using natural positioning!

I have many sizes and shapes of pistols of which none were bought because of some bore height.
Bore axis height is just some piece of data which by itself is meaningless. Actual muzzle flip will depend on slide mass, spring force, chamber pressure vs powder burn rate, flex in frame, etc. But for marketing people who cannot understand cause and effect (slight dig at business majors

), it something to pin their hopes on. If it was all that, there would not be so many choices on the market.

Haven't read the whole thread, so maybe this has already been said, but "high bore axis" always seems like kind of a meaningless, theoretical construct to me. Yes there is such a measurement, but the actual user experience of muzzle flip depends on a number of variables including your grip, the weight and length of the pistol, the ammunition you use, etc., and not only the bore axis, so it's highly subjective. Personally, I think looking at bore axis in isolation on a pistol is a useless measurement. One of the highest bore axis pistols out there--the Sig 226--is also among the most accurate and reliable off-the-shelf pistols money can buy. And people absolutely love this gun.

Just reading on paper that some pistol has this measurement that puts it in the category of "high bore axis" is, to me, rather meaningless. All that matters is, how can well can you shoot with this gun, and how does it feel to YOU? Apparently the "high bore axis" on the Sig hasn't bothered the millions of shooters who own it and love it!

The whole bore axis thing, when aimed at XD's, seems like a futile attempt to find something wrong with the gun.

I dispelled this myth to some extent on TFL:
http://www.thefiringline.com/forums/...d.php?t=281060

In fact, as shown in the pics and my measurements and some others, XDs do not have a 'high bore axis' relative to most pistols. It may be a little higher than the Glock and MP, but this may of may NOT mena anything to a particular individual, and might only be meaningful to a small fraction of 'elite' competition shooters.

But, from now on, when you are on some forum, or talking to your 'experts' at the local shop, you can throw the BUNK flag, when they start harping their 'high bore axis' myth about the XD!
