I had a G27 for a spell, and I have had a G26. They are wonderful guns, however they are bigger than the new sig. Oddly I can shoot this small gun better, I am no great shakes as a pistol shot but to keep all of the bullets on and 8 x 11 sheet of paper at 25 yards is pretty good for me. I bet someone who could actually shoot would do much better. So after 300 or so rounds I think I am going to keep the gun, I like the sights, the fact that it now holds 13 rounds, that is is thinner than a G19 or a G27, that I can actually shoot it better than I can my G19, perhaps its the trigger pull? I have gen2 19's that have had thousands of rounds shot through them, I hope this gun lasts as long, but for now unless it breaks tomorrow I am going to carry this weapon instead of my G43 or SW Shield. I am not a big sig fan, so I reluctantly admit that SIG has a winner in the P365.
