isn't the mag release ambi on the XD as well?
I had a jam in my USP last weekend, first one in 8000rds!
I saw a person using an XD the same weekend on my squad, I lost count of his jams, he was hitting it off the ground to unjam it! In the guns defence, the shooter was using reloaded ammo, but then so was I.
A few months ago another shooter was using and XD and had a handfull of Jams. That being said I think they are decent guns for the price, and I would think of getting one because they appear to have decent ergonomics and are easy to use. BUT, I would only use ammo I was sure would work in it.
They are not in the same league as a USP. You pay more for a USP, but you are getting a more reliable pistol. If you are looking for a Pistol with an easy first shot (which is a good feature to the XD), than a USP with a 6 lb DAO LEM trigger would be the ticket.
You could also try the USP custom sport. After some dryfiring and use the trigger gets smoother in DA, and the SA is good from the start.
