Not sure where you think you are posting,
No offense, but if you want to go somewhere where people will give you attaboys and make you feel better about your purchase you may be more well served on XDtalk or thehighroad.
Of course there are "no guarantees" but there are tons of accomplished shooters, trainers and industry professionals on this forum with a wealth of information to give on what "works" and what doesn't, and most people here will give it to you straight whether you like it or not.
This is not about "what I have seen" it is about, what is the standard and expectations from each manufacturer. Nobody is talking about $2500 race guns and special custom editions, we are talking about mass-produced polymer striker fired pistols; in that regard, the manufacturers I listed previously are proven performers.
