I have to agree with DeputyRet. I am also a retired LEO and carried a G-19 condition 3 (Chamber empty) for optimum safety, but there are times, such as a very close range armed robbery, where a condition 3 start could indeed be a problem. Because of that I switched back to a "J" frame S&W.
Recently had the occasion to dry fire a P220DAK. What an amazing DA trigger pull!! So, here I am reading a SIG thread thinking about carrying chamber loaded in a 220 or 226 DAK in lieu of the S&W 442. Just a thought - KW
