I have been following 10mm Glocks for a long time, and people seem to be happy with them, whether I have spoken to them in person or seen posts on the internet. I got away from the G22 .40 as a duty pistol for a variety of reasons we won't get into here, but the bottom line is that I wanted a smaller pistol I could shoot better with one hand, and the SIG P229 DAK does that better for me. My only personal history with 10mm Glocks is a G29 I briefly owned, and I sold it off with my .40 Glocks a while back, but kept the holster, spare mags, mag pouches, and a cache of 10mm ammo, because I think the 10mm Glock is a great concept, and I want to go back to it in the future, when I can afford not only the weapon but a grip reduction, as my hands are much more suited to narrower 1911-sized pistols.
