If I might differ, I just bought the Smith and Wesson SWVE 9mm. It’s so similar to the Glock that they got sued over it, yet it was $200 cheaper than the Glock was. 15+1 shots should be plenty.
But it seems to have a long and funky (that's a technical term) pull. Takes some getting used to. Also seems to be less accurate beyond 10 yards despite my flawless technique.
Have a Glock 23 - very nice and the bigger round is nice. But for me the ergonomics of the SWVE are better - not that the Glock is bad, but the SW fits better. Seems to be more accurate than the SW.
Recently acquired an XD45. Very nice fit shoots well. Overall, it's my favorite. Now if I could only find some ammo for it.
One person's opinion - weight loss is not typical and your results may vary.
