I'm looking to buy a high capacity sidearm. I don't necessarily want a typical semi-auto like a Beretta or Glock, but something that is a submachine gun style pistol like a Mac-10. Criteria for what I'm looking for would be: 1. Accurate to 75 yds, give or take. 2. At least 15-round capacity magazine. 3. No more than $400-450. 4. Chambered for 9mm (preferably). 5. Fairly reliable and durable. Thanks.
