Its good that you have been shooting them ...and happy to hear that your guns are holding up and performing well for you.
I put a lot of rounds thru my primary guns.../...2 or 3 range trips a week to practice my tactical shooting ( in and out of holster, speed reloads, TAC reloads, etc )...and then a buddy match once a week, where we shoot 100 rds to a published course of fire, timed, that I change every week...and 90% of it I use my primary carry gun ( 5" 1911 Wilson in 9mm) ...( retired guys need hobbies, so in winter I shoot a lot more handgun )...
I'm not a plus P guy either...I don't see the point -- but everything I put thru my gun in 9mm is 115gr FMJ ...or 230gr FMJ in .45 acp ( but I also reload everything, to keep my costs down / which means I don't save any money, I just shoot twice as much with the same ammo budget).
If you like the GI spec'd guns then that is what you should stay with...while I used them for many years....I'm very happy to move on in the last 20 yrs to more custom guns, and while I have had guns from Les Baer, Ed Brown, Kimber, etc...I will stack my Wilson's up against any 1911 made ../ and since I invested with the Wilson's ...no other mfg's have enticed me to take a chance on them again - and not everything Wilson Combat does, like their new EDC line of guns...( I have fired them ), is appealing to me vs a more traditional 1911 --although upgraded with high ride beavertails, better sights, checkered front and back straps, etc....
I am fortunate that my local range rents a lot of guns...and I know a number of guys at the range with other mfg's 1911's ..including some GI spec'd guns...that I have the chance to shoot and occasionally evalute. I'll stick with my 5" all steel Wilson's ...until my skills diminish to the point where I can no longer carry ...( maybe in my 80's or 90's...if my hands and eyes continue to deteriorate ...).
