I've got a g26, g19, g23 and am looking for a full size pistol or another compact (glock 19 size). I do not currently have a .45 pistol so I figured it might be a good idea to pick up one. I'm not interested in a 1911, just figure I'd throw it out there since it's so iconic with the .45acp. I'm looking for a pistol that would be appropriate as a duty weapon. I'm familiar with and trust Glocks but the SW M&P .45 really caught my eye. My LGS had one in flat dark earth for $550 and it's a full size. Reviews them seem very positive. They had a G21 gen 4 and it looked nice but it was $640, no night sights... It feels quite a bit chunkier in my hands than my other Glocks. Anyway thoughts on the G21, SW M&P .45, and what other make and models should I look at?
