Greg Cote sells Mec-Gars, and had some in stock when I ordered them in Jan. Mec-Gar is rumored to be the manufacturer of factory mags as well, and are certainly high quality. IIRC I gave under $25 each for mine. Contact him at
[email protected] for a current price list. I believe this is the current one, posted at the Sig forum (I couldn't find the one he emailed me)

You listed pretty much every complaint I had when I first brought home my 75 compact.
...and they do suck. Compared to the other 13 full size centerfire autoloaders in my safe the trigger is VERY heavy,
This gets better with wear, some guys will tell you to put a snap cap in and dry fire it a few hundred times while watching TV, but mine wasn't too bad to begin with, and I would describe it as "decent" after only a couple hundred rounds.
the slide is VERY slim and low profile, I cannot rack it unless I grab the rear sights.
This really got on my nerves as well since I was spoiled by "old slabsides". It is much easier to do the "pinching" method on the rear serrations, although some combat handgunners would chew me out for saying so. It also got easier after a couple boxes of ammo as the spring got broken in. I also sometimes thumb the hammer back, which makes it pretty easy. It is still my biggest complaint about the platform.
The magazine release does not drop the magazine, it remains in the grip and has to be manually extracted,
Stick your finger into the magwell and straighten out the spring which retains the mag. It's on the back of the well. It's also pretty easy to get out if you can't bend it enough in place.
the decocker is stiff, and the hammer lacks a spur and is difficult to manually cock unless you pull the trigger halfway (a questionable practice at best).
Can't help you here. What do you mean by stiff? You have to push it down fairly hard, but that's better than it being too light and dropping the hammer when you don't mean to. I don't have a problem with the hammer, either.
Anyway, be sure to give the gun a chance before you get rid of it. It gets better and better the more you shoot it. I was a little disappointed with mine at first, but it's grown on me a lot.
