So, you've had how many functioning issues arise during the course of firing apparently less than 250 rounds of ammunition through your 1911-style pistol?
How knowledgeable and experienced of a shooter are you ... especially with 1911-style pistols?
How well was the pistol cleaned and lubricated prior to each range session?
Were the magazines cleaned out to make sure any shipping/packing oil & general goo were gone, and then left dry before you used them?
What kind of magazines are they, anyway?
You haven't tried loading the chamber by dropping a live round directly into the chamber, instead of loading it from a magazine, have you?
Where did you buy the pistol? Did you buy it new? Do they have a gunsmith who could at least inspect it and see if anything obvious (to him) is not within proper spec on your pistol? You have a warranty available on the gun? Why not call the manufacturer and chat for a few minutes to see what they think?
I know some folks will say that new guns often require some 'break in', and I can't argue about test-firing a gun to make sure the sharp edged surfaces are mated and make sure everything is working normally before trusting it to competition or defensive application ... but I've also become accustomed to having my new guns run fine once I inspect them, clean & lubricate them and take them out to the firing line.
I don't buy 'tight' guns, though, or 'match-grade' guns.
Neither my Colt XSE or my SW1911SC exhibited any feeding, extraction & ejection issues from the very first rounds I fired through them. A good amount of the ammunition I used included Winchester 230gr FMJ (both the older American-made loads and some of the imported stuff) and Winchester 230gr JHP Personal Protection (dirty stuff, granted), as well as some aluminum-cased Blazer, Winchester T-series, Remington Golden Sabre and some other odds & ends, I believe.
I haven't kept them clean between range sessions, either, since I've just used them for training & practice, and not dedicated carry weapons (yet, since I have enough other ones which see that duty) ... although I do verify I can still see lubrication on the barrels, bushings, guide rods & rails before I shoot them. I also use good quality magazines, too.
I saw a couple of our guys fussing over a Colt Commander 'parts gun' at the bench a while back. When I politely asked what was going on, they said that it wasn't feeding and functioning right and they were going to fix a couple of things to correct it.
Now, checking the pistol I saw that it could use a little attention here & there ... but I also didn't like the feel of the magazine springs and the follower style & movement. I handed the owner a couple of good (I thought, anyway) magazines and suggested he go try the gun again, with the same ammunition. While he seemed as though he would really rather have had the gun 'fixed', he took it over to the range and fired the same Winchester Personal Protection 230gr JHP through the gun. The same stuff that had just been giving him fits. Stayed out there burning up ammunition for a bit, too.
Lo and behold, the gun ran fine. Not a bobble. Funny how some 1911's seem to prefer some magazines.
Of course, then it was time to actually invest some attention toward replacing and adjusting some odds & ends that seemed as though they actually deserved some attention. I made him a present of one of the good magazines and suggested he invest in some more. Told him to clean the gun. Order new springs (they may have been the original springs from the look of them
). Clean the gun. (Did I mention that?) Lubricate the gun.
The fellow seems to really like the gun now. It runs.
Of course, he didn't have the luxury of a new gun warranty to fall back on, having acquired a 'mongrel' parts-gun with some parts of dubious origin.
Just my thoughts. Not an expert. Not a gunsmith.
