I thought I had my mind made up on a G26. I originally wanted something bigger than 9mm but since 9mm was so cheap I decided I'd go with that. Now that I see you can get conversion barrels for a G27 I'm not sure if I want the G26 anymore. Are there any issues that the G27s have? Reliability is my number one important thing. Another question I had is will the poi be the same with a 9mm conversion barrel and the stock 40 caliber barrel? Since they are fixed sights I don't want to have to adjust the sights when changing barrels. Due to the cost of ammo I'd probably shoot 9mm 90% of the time but I think it would be nice to be able to carry 40 s&w rounds as I'm just not sure I have complete faith in 9mm. Since you all now know what I want and my concerns which would be the better choice?
