I got mine last month and put just over 250 rounds through it during two range sessions, without even the hint of a hiccup. 175 or so crappy 9mm and the rest were HST, DoubleTap 124, and a mix of HP stuff I had lying around. The only reason I stopped was because I ran out of ammo AND my face was hurting from the permanent smile:jumprope:
The 26 is MY "Holy Grail Goldi Locks", based on what is available out there. I did not like the 43 because it was too small FOR ME, so even if they ever fix the Sig 365 problems, I wouldn't be interested - as it is similar in size. I shoot the 26 at least as well as my 19, especially with a 15 round mag and GripX.
To be honest, when I pulled the trigger at the LGS, I was amazed at how "different", as in GREAT, it felt. When I actually shot it, I didn't notice it as much, but it probably did help me shoot it well. The barrel is "better", so maybe that contributed to my improved accuracy too?
I'm picking up a 12 gauge Shockwave today and hope to get to the range this Thursday. I'll also shoot the 26 and post a follow-up "review" then. You gonna love shooting this great gun!
