OK, went down to the shop today with the intent of walking out with a PT140, but made the mistake of looking at the 145. Same exact size and capacity (10+1)and 2 .oz heavier. So now I'm torn. Never shot a .40 period, haven't shot a .45 in ten years or more. I'd like some opinions on what to expect from both these rounds in a little gun like that (3.25" barrel) I'd also like to know your opinions on whether or not the .45 is a suitable replacement for a .357 as a "backcountry gun" for the chance bear encounter. I could buy the 140/145 and save the extra towards the next purchase (AR-15) rather than buy the Tracker .357. Any input is appreciated. (and pip, I read your angelfire link from the CCW thread and there was some good info there!) Thanks guys!
