When I first went out back with the 43, set up a target at 25yds, and put 5 of 7 dead center inside 2" with one out 3" at 10, and the other same distance at 8 o'clock, standing/unsupported, was too impressed with the gun to pay attention to magazines.

Continued burning ammo through both magazines, went back inside, and only then, remembered one had an extension, and never noticed the difference when shooting.

Since this is a hideout for belly or pocket, was mighty pleased no extra bulk required, and the flush mags are the carry mags, extras were ordered, 6+1 gives same as a 1911 carried milspec, so sacrifice of easy hiding is just not worth it to me, and may as well carry a larger gun, such as the 17, which works better for concealed than even a 1911 as for belly, M65 or N3B pockets, etc. Again, much depends on build, hand size, clothing worn, job description, etc on what works, and many folk require a longer handle on a 43 simply to get a locked in hold, but I am not of that number.
