We purchased a Glock 43x to replace my wife's 43. I installed a Warren Tactical 43 fiber optic set on it and rubber talon grips. I took it to the range last weekend to see what's up with it, and I was on the struggle bus with it quite a bit. I shot some at 25, 15, and 7 yards and marked holes accordingly. I felt like the gun was shooting both high and left for me with the rear sight centered. I couldn't get a good group to save my life in the few rounds I fired. It was a bag of random ammo, so this was not a good first test. I plan on getting some quality 147 grain ammo and trying it from a rest. If it really is shooting that high, a taller front site is needed for sure. i really wish Warren Tactical had the selection that Dawson has, I like their design.

For comparison, I decided to shoot my beloved Glock 45 at 7 yards with some holster drills and head shots before cutting it short to perform my RSO duties for the day. This gun has Taran Tactical sights and a stipple job, everything else is factory.

I don't get along with the small guns at all, and I don't think I want to since the Glock 45 carries well for my large frame. Fun fact, for as much fuss that was made about the 19x/45 not being good for concealed carry, when you compare the measurements it's actually a slightly smaller dimensional package than a commander sized 1911 save for it being a little wider. I compared it to the Colt commander, the Springfield Armory Range Officer Champion, and the Ruger SR1911 Commander. A lot of people CCW those guns and no one raised an eyebrow.
