On a note...
You should be somewhat careful in the handling of your mags. If you drop one on the top magazine 'lips', You can damage the mag to where it won't load into the well properly, or allow the slide to strip rounds outta the mag as it cycles.
About a year and a half ago I went shopping for a semi-auto, something in the .40 S&W- to .45 ACP category. After looking at quite a few offerings all through the different price ranges(Kimber, Glock, a Taurus, S&W, Even a Springfield XD) I decided on...A Ruger P345.
The price was more affordable, although I had to settle for a gun with a Poly Frame( Not a problem after 250 rnds., but I still kinda wish I'd went Metal-Framed)I passed up a XD for it. Partly, the Springfield they had was a .45 GAP. I knew nothing of this round, aside from the guy behind the counter saying that even though the case was shorter, propellant advances gave it almost the same ballistics as a .45 ACP.
I've been more than happy with the ruger, but only time will tell with it. It's a simple gun, very easy to fieldstrip/ Put back together and clean. It has good enough accuracy for a gun in it's class. If I wanted a super tackdriver, and had 1,200$ to spend, I'd have gotten a Springfield V-16, But it's not what I was in the market for.
Halo, I do have one question for you. Do you have kids in the house? If you do, then I would include in your loading drill, the time it takes to get the lock off. I live here in Cali. Now, the law says you have to have a lock when you buy a firearm. I keep mine locked, which is a 4" padlock that goes through the weapon with the slide locked back and no magazine in the well. I always keep the key within 2' feet of me, even when I sleep. I've drilled with it, and you can get the lock off fairly quickly...But you always wonder when that lock may choose that moment to jam, or the key to snap off.
I'm not advocating that you DON'T use a lock...But, If it's a factor where you live, It is something else you should consider.
P.S. When the gun IS locked up, or you are locking it up, careful feeding the lock through, you could potentially damage internal parts, increasing the chance of failure.
