Glocks are still better.
But I have been tempted to look into a shield...
I've said it many times on this forum over the years, when discussing "best for me" polymer carry sidearms. I used to own Glocks, and never really warmed to the ergos. I moved to the M&P platform not long after they came to market, and suffered many slings and arrows from the Glock sycophants as I tried to tell the World about the awesome new line of handguns. Today I have moved almost completely away from the M&P platform to the amazing Walther PPQ line of pistols. All of this has been done to find polymer pistol nirvana, and I can only say that perfection takes many different forms to many different people. I'm just glad that so-called perfection didn't end when Gaston introduced his version in 1982.
PPQ.
It's unfortunate that the PPQ M2 isn't more popular. In an ideal world, we'd have the same holster selections as Glock and $20 15rd and 17rd magazines would be plentiful.
Aside from being the standard for reliability and durability, the ubiquitous nature of Glocks grants a much better selection of accessories.
