Wannabe Glock....yeah...right....only a die hard Glock fanboy would use that analogy....as usual we all have our own opinions...i on the other hand sold my Glock...very much prefer the ergos and feel of the p320...and I'm looking forward to trying the X5....just sayin.
How is it not a wannabe? It's a double action striker fired design, first popularized and made decent by Glock. The 320 has the same goofy toe on the front of the trigger guard just like a Glock. The slide stop is very small and unobtrusive just like a Glock. The only thing SIG did differently is offering a modular chassis which does nothing for performance or reliability. So SIG like Springfield, S&W, Walther, HK, CANIK, Beretta, FN, Ruger, Remington, Strike industries, CZ and others have done nothing to improve either performance or reliability with striker fired pistols, they've simply copied the base format and act like it's something new.
Glocks have been around for over 30 years and SIG, HK, Ruger, and others are just NOW figuring out that striker fired guns are an improvement? If these companies were so cutting edge they would have copied the recipe decades ago(like S&W who got sued for patent infringement). Instead they are simply hopping on the bandwagon in an attempt to capitalize on Glock's long standing reputation with striker fired guns. Even the abortion that is the Hudson H9 is trying to ride the wagon. Striker fired 1911 in 9mm, an attempt to make sales to the ignorant blind patriots that still think the 1911 is the greatest design out there but with the modern flair of striker fired.
The most ironic part about all of these wannabe offerings are the near identical similarities many share with a Glock. Back in the day people poo poo'd Glocks and talked sh*t about their control layout/design/size and said that polymer is cheap junk. Now every poly striker pistol out there shares at least a couple of those "bad" features and everyone is singing praises for their brand. The reality is that none of the wannabe offerings does anything better than a Glock and most don't come close to meeting the performance and reliability of a Glock.
As for "ergos" that is just window dressing. If you can shoot you can shoot anything, the interchangeable backstraps and minutely different grip angles etc etc are just marketing gimmicks. Either you can apply the fundamentals or you can't.
