I have carried a full size GI Model for nearly two decades now, and I have to say I'd pick one of the many 1911's I've owned or still own over a striker fired pistol for two main reasons. 1.I just can't believe the difference in recoil a polymer 9mm or 45ACP has when compared to a heavy framed 1911 45ACP and 2.Though some 1911's can be finicky about certain ammo types, just about everybody makes a SD round that will feed well while others refuse to. (In my case with my current, I can't shoot speer gold dots or sign v-crowns) I usually handload some Hornady XTP 230 grain HP's over some CFE pistol for snappy SD loads or some Longshot if I want something not as stout. I also love accurate No.2 it's a great powder to get the cannonballs flying. To me there isn't a gun that can be more safe to carry, I carry appendix carry in a leather IWB holster most of the time, in the winter time like now I usually carry in a shoulder holster so I don't need to remove my gun to sit down comfortably, plus I like a vertical shoulder holster over a horizontal one for ease of concealment, I'm not a thick tall guy. I'm 5'9" and 135 lbs but have shot 1911's and 357's since I was 13. I never even touched a polymer pistol until I was 25 and I didn't enjoy that experience very much, it was a Ruger P85 in 45ACP and holy hell the recoil difference is night and day. Right now I carry a Taurus PT1911 in 45 ACP. I got it for 300 used and just got it for a beater pistol but it has actually been pretty rugged and reliable, it's got some rust and almost no finish left on it. Despite the weathered look it's taken some ridiculous hot hand loads and I've replaced a ton of parts like my barrel bushing, seer spring, ambi thumb safety, recoil spring, and the slide stop spring and pins. The bushing is a pistol smiths bushing by Wilson Combat I didn't even have to sand it or nothing it slid right onto my barrel and was super tight but wouldn't bind up during operation, and I switched the 18 pound spring for a 20 pound and it seems to work better with the heavier spring...I love the 1911 and I don't mind the limited capacity on mags I carry two ten rounders as backups and I'd gladly trade off the capacity of a poly pistol for the adjustable trigger on a 1911 any day of the week.
