Sig is my fav mfg. and I love mine, will take any Sig over any Glock. All mine are both incredibly reliable and incredibly accurate.
That being said, Glock is a good weapon or so many would not be using them.....
Wilson Combat is the only 1911 I’d swap for my Sig......
Taking one gun over another is no different that if you like blondes or brunetts. Its what suits YOU. I had both glocks and Sigs and both were good weapons. The one tht fit and suited me the best was the one I carried. Simple as that. Never had a problem with any of them.
Note too that the PD went to 45’s versus 40’s. They must not be in the loop with the DHS which is buying all that .40 ammunition for a “just in case we need them” senerio.
Like others, I think there is more to the story.
If SIG made a 10mm with 15 round magazines, I’d own one of those, too. That said, my near 20 year old Glock mod 20 runs flawlessly, so I have no objections there. Could use more 10mm brass, though.
