XD ALL THE WAY!! especially if your accustomed to 1911s, the trigger is an easy fix if ya don't like it, I've retuned my reset, pretravel and stop to exactly match my 1911s on all of my XDs, ya simply cannot do that with a Glock due to the Glocks partially cocked trigger, the XD is a true single action, secondly and more importantly the grip angle of the XD is exactly the same as the 1911 makes transition to polymere that much easier. The XD has a hammer forged barrel with fully supported chamber that rivals many match grade barrels right outa the box.
want custom sights? The XD uses the same sights as Sigs so there are ALOT of options. Want durability? The Glock was designed to meet POLICE issue specs and it does so nicly........ The XD was designed to meet MILITARY issue requirements from the beginning as the Croations needed a super durable ultra reliable sidearm for their military forces, in case ya've never seen any of the AK47s or other weapons that came outa Croatia following the Croation/Serbian war........ they are extremally hard on their guns, much tougher on em than we are in the USA and far much harder on em than the POLICE officers in Austria that the Glock was designed for.
I was a diehard 1911 fan untill I got the first 5" tactical .40 XD (the .45 hadn't come out at that time, I got one of the first tacs that hit Az) that gun actually gets more use than the XD .45 that later followed it home the really nice thing is I can load for minor or major in the same gun, I load 155 grn Hornandy XTPs to the exact same POI as my 180 grn XTPS and my cast bullets in each weight are also loaded to the exact same point POI, one gun just swap mags and change classes!!
I now have the entire XD lineup, sold off my Glocks except one M17 that just sits in my collection to at least represent Glock (I have quite an extensive gun collection and the glocks are the ONLY guns I've ever sold from it) Glocks just really don't do it for me the grip angle is just wrong, the lockwork... its just no comparison to the super simple single action plus the XD has the extra grip safty that ya will never even notice if ya shoot 1911s but it sure is handy when something like a holster strap or shirt etc.. gets into your trigger gaurd with the glock....... BANG the XD.... nothing the grip safty wasn't depressed as well...
