I've owned a Springfield Armory P9 in .45 ACP (same as EAA Witness) for over 10 years and my only complaint is that the barrel's chamber is a tad too tight and reloaded rounds sometimes get stuck. No problem with factory ammo, though.
Some people might object to the grip, but the gun fits my large, skinny hand better than anything else, except my SIG P220. The SIG is my house gun, while the P9 rides in the vehicle at all times.
The fact that you can purchase additional slides/barrels/magazines for it for not too much money makes this handgun one of the best buys for the money.
Regards,
JB
