I love them both equally. How is that for no help??? No seriously both platforms do what they do exceptionally well. They are two different animals. The P227 is truly a combat handgun and feels like a Swiss watch. The down fall to all this is it’s weight. It’s heavy to carry but that goes with what it is. My P227 is a custom shop and then some type of gun so it is one of the smoothest DA/SA Sigs you will ever shoot. The PPQ45 is bone stock internally and doesn’t need anything. Honestly I believe you could (and should) own both of these guns as they compliment each other. My P227 is one of my bed side handguns because I like DA/SA guns for the bump in the night duties. It also wears a 800 lume light which it’s platform carries very well. Polymer guns are workhorses that I won’t cry if they take a hit on the side of the vehicle getting in and out. The Sig all metal frame and G10 grips might make me cringe only because I mentally baby them a bit more (not that they are not just as tough). I literally own about every hand gun that is carried or used by LE and various military. They are tools for me. My duty hand gun varies from a G32 to a USP Compact in 40 or 357Sig. They are tools and I don’t care if they get chucked across the parking lot in a struggle. I do occasionally carry the a P226/P227/P229 on duty but their extra weight over the G32 becomes apparent an the end of the day. Weight is really the biggest downside of non polymer platforms and sums up why I carry polymer guns 90% of the time. I have my duty holsters set up for mainly three platforms of guns. A G23,G32,G19,G30s. All of those can and do get carried on duty. My Sig rig holds my P229,P226,P227 size platforms. The only oddball rig I use is for my HK USP Compacts and I own them in every caliber (9,40,357Sig,45acp). These three duty rigs allow me to carry a plethora of handguns. I have a Sheriff Dept shooting the PPQ45 and I will strap it on when visiting them. I deal a lot with various levels of training within the LE departments. If they carry a G17, then I will showcase ammo or gear for the G17. The tactical guys that have a more open end line of gear is when the different calibers and more expensive platforms are appreciated. My biggest issue with the PPQ in general was proper LE duty holsters. I worked directly with Walther on this issue. Walther needed to understand was that LE Dept buy handguns based on a platform across the line. Glock being the most common and easily to accommodate and what most used. To get a LE Dept to switch to a PPQ, I had to sell the buyers for the Dept on the idea that they need to also buy all new holsters and in some case extra magazine pouches. This made the PPQ a tough sell even though it shoots so much smoother and oozed high quality. It almost always boils down to money in the end regarding platforms and calibers.
